Description

2092 ^ 0 Λ 6 Π 6 The Ministry of Economic Affairs has approved it and the A Gongxiaozhong Cooperative Society printed it. V. Description of the invention (1) Field of the invention The present invention is an on-board media containing a rake and a partial fuel tank. Method, in which the fuel is partially burned by the catalyst. This rake catalyst can also contain rakes mixed with VB or IB group gold hurricanes, which can be graded so that the front of the medium is more active or placed on a carrier containing gasification knots. The above-mentioned catalyst and load-bearing choices have solved many long-term characterization problems as part of the combustion catalyst rake. The catalyst structure is stable in the bank, has a relatively low operating temperature, a low initial oxidation temperature, and is not prone to temperature &quot; runaway &quot;. The gas produced by a typical catalytic process is at a temperature lower than the spontaneous combustion viscosity, and can be used at this temperature, or sent to other combustion sections for further use in gas turbines, kiln bows, pans, etc. Background of the Invention In the United States and around the world, with the advent of modern anti-pollution laws, new and effective methods for minimizing various pollutants are being studied *. Fuel, whether it is wood, coal, oil or natural gas, its refining is the main cause of many pollution problems today. Certain pollutants (such as S02, which are pseudo-caused by pollutants present in the fuel source) can be removed either by treating the fuel or by treating the final exhaust gas. Other pollutants, such as a gasification sieve (which are all produced by incomplete combustion), can be removed by gasification after burning or by improving the combustion method. Other major pollutants, NOX (a balanced mixture. Most of them are Ν〇ι but also contain a very small amount of NO2) can be removed by controlling the combustion process or by the latter to minimize the generation of NOx. H0X is produced once, because of its relative stability and its concentration in most exhaust gases, it is not easy to remove it. A kind of solution found in the automobile.

Description of the invention (2) The method is to use one gasification sieve to reduce it to nitrogen, and one gasification sulfonate to be gasified to two gasification sieve. Nonetheless, in certain combustion processes (for example, gas turbines), the concentration of monosulfurized sulfonate is insufficient to react with and remove 1 &lt; 〇5 &lt;. It must be noted that unlike sulfur pollutants, sulfur pollutants can be removed from the fuel, and it is obviously impractical to remove nitrogen from the air input to the refining process. Unlike the case of sulphur monoxide, due to the higher temperature during the refining process, improving the combustion reaction may increase the newly produced Νγ content. Nevertheless, the challenge of reducing 1 &lt; 0 &lt; during the combustion process still exists, and several different methods have been proposed. The method used to reduce Ν0 &lt; must be substantially inconsistent with the objective of generating combustion gas, which is to use a turbine, a boiler or a kiln to recover the calorific value of the gas. Many people recognize that in the turbine feed gas, an effective method for controlling the production of Ν0 <during combustion is to limit the local and recombination temperature of the combustion zone to less than 1 800Ό, see, for example, U.S. Patent No. 4,731,989, first column, lines 52-59 and Hindin et al., US Patent No. 4,088,135, 12th column. There are many ways to control the temperature, such as dilution with excess air, one or more catalysts to control gasification, or the use of various lean or enriched fuel mixtures for staged refining. The combined use of these methods is also known. A widely tried method is to use multi-stage catalytic agents. Most of the published methods are multi-stage catalysts that use metal vapors on ceramics.

Note: The catalyst in the table is shown as “a &quot;” / b ”, where a is an active metal and "B &quot; is contained". However, in some methods, it is difficult to control the intermediate temperature or interstage temperature. Because the goal of these methods is to generate as much heat as possible in a form that can be effectively used in some post-process, the combustion stage is basically adiabatic. Therefore, any slight changes in fuel rate, air rate, or operation will cause significant changes in temperature between segments. The very high temperature causes thermal plaque changes on the catalyst elements of the subsequent mines. In this paper, there are 8 and 8 "CNS" T4 specifications (210X29 / M;!

Description of the invention (5) The table clearly shows that the platinum group including the harrow is useful in the process of valued combustion, However, the traditional catalytic combustion process is usually to mix fuel and air, and then pass the seed mixture through the catalyst on the catalytic bed to cause substantially complete combustion. This leads to high rents, generally ranging from 1100¾ to 1500¾. To this end, more catalyst development work is aimed at those catalysts and carriers that can withstand the temperature and retain activity. Some studies rely on control methods. In some methods, the intermediate air or fuel flow is introduced between the different catalytic stages, and the flow rate is controlled according to the temperature of the whole plutonium. The above-mentioned Furuya et al. Describe a method to overcome the problem of temperature separation between mediums, which is to dilute the fuel / air mixture by inputting air to the medium so that the resulting mixture has an adiabatic combustion temperature of 900C to 1000t: . The seed mixture is exposed to the catalyst, and the temperature of the catalyst is partially or completely reversed so that the maximum temperature of the catalyst does not exceed 1000t :, and the gas * rent does not exceed 1000t :. After the catalyst and the seed mixture are uniformly burned to obtain the desired temperature (1200¾ to 1 500 Ό), additional fuel is added. However, the disadvantage of the seed method is that the fuel needs to be added in the two eaves section, and the additional fuel of the seed needs to be mixed with the hot gas Nf β without obtaining the traditional temperature-diffusing diffusion flame and the corresponding NO product. The method of the present invention mixes air and fuel in a certain ratio at the beginning of the combustion chamber, so that the final combustion degree (after further combustion or several combustion steps) is for some post-mine encounters or from The device that recovers heat from the fuel gas, that is, the gas transmission, is needed. A typical mixture may be a mixture of methane and air, the mixing ratio of which is η.043 for the fuel body 稹 / air «I 稹. The seed mixture (after preheating to 350t :) can produce a combustion ancestry of about 1 300 T3. The seed mixture is divided into two on the catalyst and the catalyst is used to make it happen only in this paper.

Description of the invention (6) Partial combustion, and limit the maximum catalytic temperature to a value significantly smaller than that of the gas trap. Thermal combustion temperature. The limiting effect is believed to be due to the following reaction: 1 PdO-> Pd +-0 2 2 There is a partial pressure of gas and gas during the reaction. The limited temperature has been found to be in thermogravimetric analysis ( The conversion temperature of the rake / gasification rake obtained in TGA). Roughly speaking, the conversion temperature of the pure rake in the latB air is about 780 ¾ to 800t :, and in the 10 value atn air is about 930 to 950T: I have found that the palladium catalyst will become unstable in part of the burning lotus row. After a period of time, the reaction stops and the preheating temperature level required to stabilize the lotus row is also raised. For the Dao problem, I have found many solutions. For example, I have observed that One or more of the following measures, there will be a stable temperature self-controlling to stick. A. Use a rake (and leave any other VBI group precious gold hurricane, such as platinum, osmium, grandma, ruthenium; preferably platinum; or optional IB group Jin Yi, such as copper, gold, silver; preferably silver) as the active catalytic metal. B. Coating a diffusion barrier layer on the surface of the catalyst to limit the diffusion of fuel to the surface of the medium, thereby limiting the rate of the catalytic reaction , Which in turn allows the rake to limit the maximum temperature. C. Use a chromium oxide-containing carrier (preferably placed on a gold substrate) to carry the catalyst layer to provide a very "heat shocked" medium structure, or d. Place the catalyst metal on the carrier «so that the front part of the structure of the contact with the flowing air contains a highly active catalyst material. (Please read 1?

Description of the invention (7) In front of, for example, Furuya et al. No. 4, 731,989 has described that the gasification rake and the mutual conversion of the rake are about 800Ό, however, the Yiyan patent is used as a disadvantage to describe the seed producer, because the active gasification rake is converted into a less active rake , So as to prevent the combustion reaction on the suspected medium from going to completion. The method of the present invention utilizes the conversion process of the oxidation rake / rake to stabilize it and promote its occurrence in different ways. Thereby (very) highly active and stable media can be used. By maintaining the temperature of the catalyst significantly below this adiabatic combustion degree • it is in contrast to the thermal sintering of the catalyst, the evaporation of the rake and the thermal shock of hunger Some problems of contact can be greatly reduced or eliminated.

The method of the present invention also provides favorable conditions for the use of ceramic liners due to the limited liner temperature. Because the liner temperature is reduced, the thermal plaque force is reduced, and when the combustion chamber is started and closed, the thermal shock is reduced. failure. The fuel / air ratio of fuel protection is equivalent to adiabatic combustion temperature of 1 300¾ to 1600T, which is particularly important. In short, although the literature proposes various non-pioneering parts of the method and catalyst structure of the present invention, none of these documents propose the catalyst contained in the present invention (in addition to stably limiting the liner penetration) Of sticky.

In addition, the combustion medium can be segmented, and the front of the structure of the medium can have a portion with higher slap activity. The present invention includes a partial combustion method in which the fuel is partially burned using the catalyst. The selection of the medulla was used to solve the problem of long-term stability as a part of refining medium in this technical field. The "medium structure" is stable in the lotus row, has a relatively low operating temperature, and has a low "point" thickness, but it is not prone to temperature runaway. The gas produced by the catalytic process can be below the spontaneous combustion temperature, it can be used at this temperature, or it can be transported to other combustion stages for further use in gas conveyors, sleepers, and grade furnaces. 1 and 2 are close-up schematic diagrams of some catalysts in the fan garden of the present invention.

Description of the invention (li) The present invention is a combustion contact with rake It can also contain Group IB or Group VI precious metals and can be placed on a chromium-containing carrier. Moreover, the combustion catalyst can be segmented, that is, it can have a more active part at the front of the medium structure. The present invention includes a partial combustion method in which the fuel is partially burned using the catalyst. Yun used such "medium and carrier" to solve the long-term stability problem of Lan Yurak as a partial combustion catalyst in the technical field. This susceptible medium structure is stable during operation, the operating temperature is low, and it has a low &quot; lighting off &quot; temperature, but it is not easy for the temperature to "runaway". The combustion gas produced by the catalytic process can be below the spontaneous combustion temperature, It can be used at this temperature, or sent to other combustion stages for further use in gas turbines, kilns, boilers, etc. This catalyst contains rakes, and can also contain any one or more of the Vffl family of gold beryllium (platinum, ruthenium, grandmother) , Osmium, iridium, platinum is preferred) or Group IB metal (silver is preferred), the number of which is at most equal to the number of moles of the rake. At a temperature of 325 t: and below, the rake is used as It is quite lively, so it can be used in part of the combustion process as a "stick-extinguish" catalyst. As discussed earlier, the catalytic activity of the rake as a combustion gasification medium is according to the existence of the gasification rake. As a "medium rake", the medium is not very active except at relatively high temperatures (such as above 750 ° to 8001). In the presence of excess gas, the Jinyi rake can easily be oxidized into an oxidizing rake according to the following equilibrium at a temperature as low as 325¾: 1/20 + Pd—PdO However, when the temperature increases, the equilibrium moves to the left, That is, the gasification rake is decomposed. Such a change makes the reaction temperature self-limiting.

Description of invention (12) Burning makes the temperature easily reach 750 ° to 800¾, and there are fewer gasification rakes during manufacturing Species, thus slowing down the reaction. The temperature at which the gasification rake is converted into the rake depends in part on the partial pressure. The conversion temperature can be easily determined by thermogravimetric analysis (&quot; TGA &quot; —method of measuring the weight loss of the gasification rake sample as the temperature increases). PdO — Pd conversion paste establishes a substrate temperature that is self-limiting under this operating condition. The rake catalyst used as a combustion medium will generally limit the substrate temperature to the TGA limited conversion temperature. However, I have found that using rakes on some substrates (especially those containing vaporized aluminum) will result in a partially vaporized catalyst with an unpredictable lifetime. Although the resulting decrease in the outlet temperature can be very dangerous, the cause of the loss of activity is still unclear. The effect of the plaque can be used both on the gold-coated aluminum carrier and the pure gasified aluminum. see. Adding some suspended VI [Golden Noble King or IB Gold King (such as platinum or silver) to the rake catalyst will cause the medium composition to produce a long-term ear qualitative, and basically will not color the rake catalyst. With a desirable low &quot; adhesion-extinguishment &quot; temperature, we have also found that a catalyst carrier containing oxidized raccoon dogs (preferably in the form of knots) can also partially gasify the rake base. The state of performance is stable. The amount of added barnacles should be sufficient to provide catalytic activity. The amount of added barium depends on many conditions, such as fuel used, economy, activity, life, presence of pollutants, etc. (Rake) Jin Yang ’s theoretical maximum number is about enough to cover most of the substrate without causing inappropriate growth of the gold crystals and the accompanying reduction in activity. The following are obviously factors that are against each other : The largest "medium activity requires a more distant surface coverage thickness, and a higher surface coverage thickness will promote the cost-reduction between adjacent small crystal embellishments.

Moreover, must be considered Lu media « If the load is used in a high space velocity environment, the catalyst loading should be high, so that even in the case of short residence time, it can maintain a sufficient conversion rate, as its knot target, economic It is hoped that the minimum amount of catalyst gold can be used to complete the required tasks. Finally, the presence of pollutants in the combustion requires the use of a higher loading Dong * medium to offset the reduction in catalyst activity due to factors. The content of palladium metal in the compound should generally be from about 0.01¾ to about 2 5 χ (reset), and the amount is also affected by the feed ingredient's shadow sauce. You can pass the rake complex, compound or the dispersion of the Jin Yi, It is incorporated into the skull in various ways. This compound or complex can be dissolved in water or boron. The rake gold can precipitate from the solution. The liquid mongonium usually only needs to be evaporated or decomposed from the medium. Removed from the mule, leaving the rake in a dispersed form Examples of complexes and compounds suitable for the preparation of the catalyst rake used in the present invention are the nitrate of the rake: dichlorinated dinitrite rake, nitrate nitrate, chlorinated chlorinated rake; chlorinated nano rake , 2-ethylhexanoic acid rake and various other salts or complexes. Although the catalyst prepared by the helium compound is generally highly active, when the catalyst is used in the burner of a gas engine, Helium is not the best choice. Chloride (even in small amounts) will obviously cause corrosion of the vortex lobes and scorpionfish. Therefore, the nitrogenous rake is the most desirable. As mentioned before It can be found that the catalyst may contain an added catalyst, for example, a IB group gold knot (such as silver) or a VB group noble gold knot (such as platinum), the number of which can reach slightly more than platinum in the catalyst composition The amount of rubbing.

Description of the invention (U) Metals can be added as a complex, compound or Jinyin dispersion by incorporating it into the liquid-bearing skull containing the handle, if the Jinyong is added later In the step of adding, the stability of the obtained media is more predictable. The platinum complexes and compounds suitable for the preparation of the catalyst used in the invention according to the wishes of the present invention are the raking compounds: dinitrite dichlorinated platinum, platinum nitrate, tetrachlorinated platinum chloride, platinum chloride And various platinum salts or complexes. Other Group VI noble metals or similar salts and complexes of Group IB alkaloids are known. As also mentioned earlier, I have seen that the use of a "medium structure (the front of which has a higher activity than its rear part) will result in a structure with the following advantages: better" Impact "temperature , The latter part of the catalyst structure does not have "hot sticky", and it is always a kind of medium with stable lotus performance. The segmented structure can be made in many different ways, as shown in circle 1 The substrate metal or ceramic (102) can be coated with three different media (104, 106 and 108). Each media has different activities: 104 media has the highest activity and 106 catalyst activity is medium, The 108 catalyst has the lowest activity. 104, 106 and 108 catalysts can be obtained by changing the loading amount of the active catalyst material. For example, 104 »medium contains 20¾: rake, 106 catalyst contains 10Χ rake, and 108« The media contains a 5X harrow. Another method is to disperse the rams by raking 104 with the highest dispersion and 108 with the lowest dispersion. Another method is to use a thin coating to obtain a segmented catalyst. A thin coating contains both The material contains a medium with a constant activity, and the thickness changes along the catalyst.

Description of the invention (15) A thin film of catalyst with constant activity «Applied to the substrate (110), applied thickly at the entrance (112) (with higher activity ), Thinner in the middle (114), and thinner at the exit (116). — The third method is to use a medium with different activities to coat the thin layer (such as circle la) but make these thin coatings overlap Layer (such as 圔 1C), a low-activity catalyst with a coating (120) is applied on the slap substrate (118), then a part of the substrate (122) is coated with a thin layer of moderate activity, and finally only the entrance is coated Covered with a highly active thin coating (124). In addition, a structure is shown in Figure Id, in which a highly active thin coating (126) is first applied at the entrance, followed by a medium active U28) Low activity (130) thin coating. High, medium and low activity thin coatings can be made by many methods. Active components (such as rake) can vary from high concentration to low concentration. In addition, the dispersion of active rake can be Common use of different preparation methods or heat treatment of the medium at different temperatures to obtain changes. Another method is to change the surface on which the active component is deposited. For example, for a rake / single 10 or 2/2. Catalysts that use different surface areas of AJL ^ 0 $ or ZrO ^ loaded mules will produce catalysts with different activities, and loaded mules with higher surface areas will have higher activity. The construction of these segmented catalyst structures can be prepared by encountering several methods. For example, the structure shown by the circle Id can be prepared on a single ceramic peak-and-socket sheet H by partially immersing the sheet into the coating solution and blowing excess coating solution out of the channel. Then, after the encounter, the single piece is immersed in the coating solution more deeply. The same general method can be used to prepare the structure of the lc. The same method can be used on metal monoliths. The Jinyi single H is made by rolling metal foil or spiraling cylinder or folding gold foil into the desired shape, if it is made (please read first-back to the left) Please fill in this page again for sad matters) Binding-Order 'Line · 81. 6. 10, 〇〇〇 Zhang (H) 17 Η 6 Ministry of Economic Affairs Central Liangzhun Bureau A industrial and consumer cooperation cooperation du printed five, invention description (16 ) The ceramic monolith described impregnates it. Another method is to apply the segmented “medium layer” to the appropriately corrugated gold foil, and then fL into a spiral structure to form the final catalyst unit. The coating liquid is sprayed or brushed onto the surface of the metal foil, or applied by other commonly known methods, such as chemical vapor deposition, sputtering, and the like. In order to obtain the desired catalyst with a segmented structure, the foil can be partially covered to limit the catalyst to only the desired area. In this way, the structures seen in Figures la, lb, and Id can be prepared by spraying or brushing onto the foil. The coating liquid can be applied to only one side or both sides of the metal foil H. It should be noted that in these combination methods, the medium can be applied as a composite mixture of active catalysts (such as rakes) and ionophores (Aer y〇v Zr〇i, Si〇i, etc.). These will be prepared by impregnating the rake on the surface of high surface oxide powder, burning it, and then converting it into a glue. In the second method, the high surface area coating fluid can be applied to the single sheet or the gold foil first and positioned. Then, the suspected medium (such as the handle) can be applied through the same dipping or spraying process. The structure shown in Figure Id can be prepared by using a single coating liquid vapor solution and a single medium (barrier) solution, and then repeating this method. Circle 2 shows another list of suspected media, in which the catalyst coating is made by any of the methods discussed above. In 鼸 2a, the thicker (and therefore more active) media (202) It is placed upstream of the thinner catalyst (202). Similarly, in Figure 2b, a shorter but thicker layer (208) is applied. Different from Hui 2a, a configuration can also adopt a catalyst with higher activity or a higher level of preheating.

Description of Invention (17). _2d means constant change. For seed production, the better medium for the medium is Jin Yi. Honeycomb-shaped, corrugated helical screw coils (which can be stacked with flat partitions Η), columnar ("handful of straw"), or other longitudinal channels with high spatial velocity and minimum pressure drop The structures are all suitable for the use of the present invention. They are malleable, can be easily installed and connected to the perimeter structure, and have less resistance to airflow because its walls are easier to make than ceramic carriers The wall is thinner. Another practical advantage of Jinyu Zaoying is its ability to withstand thermal shock. Such thermal shock occurs in the combustion engine, when the turbine is started or stopped, especially when the turbine must be fast. When closed, in the latter condition, the fuel is cut off, or because the physical load of the turbocharger (such as the hair unit) is removed, the soup is "tripped" (tripped). The fuel to the turbine is cut off immediately to prevent overspeed. The S degree in the combustion chamber (where the process of the present invention occurs) quickly drops from the combustion temperature to the temperature of the compressed air. This drop may exceed 1000¾ in less than 1 second. No matter how the catalyst is deposited (or placed in other ways) on the wall inside the channel, the number is as described above. There are several types of Qiang materials that can be intentionally used for various purposes: aluminum, aluminum-containing or aluminum-treated steel, and certain stainless pins or any high-S gold alloys, including «Medium can sink An alloy of cobalt or lanium on the surface of Jinjin.

Description of the invention (18) Sold by Kawasaki Dysprosium Corporation (River Lite 20-5 SR), Vereinigte Deutehse Metal Lwerke AG (Aluchroa IRE) and Allegheny Lu-dlun Steel (A lfa-lV) contain enough dissolved aluminum so that when vaporized, these aluminum produce vaporized aluminum crystal bristles or crystals on the surface of dysprosium. This provides a rough and chemically active surface to allow the coating to better adhere to it. After the vaporized aluminum whiskers have been formed, these pins can be treated with a knot-containing compound, or better yet treated with a gasified raccoon dog or hydrated gasified suspension or sol. The rake compound and any other catalyst precursor are generally applied to the oxide junction coating, although it is also possible to incorporate europium coating formulations. The miscoating can be applied with one or more vaporized chromium solutions or mixed oxides (mixed oxides contain additions of silicon, titanium, or barium, selenium, lanthanum, chromium, and many other components). After the suspension is applied, it can be dried and burnt to produce a high surface area adhered vapor layer on the surface. The coating layer can be applied in the same way that people apply paint to a surface, such as spraying, direct application, and dipping the carrier in the coating material. Another method to add the susceptor layer to the plaque-bearing structure is to first add the catalyst Jin Yi to the inert vaporized powder. The "Mei Jin Yu" is fixed on the gasified substance by heat treatment or chemical treatment. The rake / inert gasification mixture is then milled to produce a colloidal solution. Then use the method of spraying, dipping, etc. to apply the solution to the pad. Aluminum structures are also suitable for the present invention and can be treated or coated in essentially the same way. Aluminum alloys are more ductile and may deform or even melt within the operating temperature range of this method. Therefore, they are not very ideal to contain 81. 6. 10,000 sheets (H) 20 Ministry of Economic Affairs Central # quasi-bureau employees Xiaozhong Cooperative Society Yin Yu V. Description of invention (19) But if the temperature specification can be met, also can use. The coating layer, rake, and any other added "medium metal once applied on the metal carrier and burned, you can add one or more layers of refractory oxide coating layer as a diffusion barrier layer to prevent the above Discuss the temperature &quot; Runaway &quot;. The barrier layer can be vaporized silicon, chromium oxide, titanium vapor, or other oxides with low catalytic activity for fuel vaporization, or mixed vapors or vapors with additives similar to those in the coating layer above . Vaporized aluminum does not seem to be suitable as a barrier layer, but it can also be accepted in certain environments. The thickness of the barrier layer may range from 1 «of the thickness of the coating layer to significantly greater than the thickness of the coating layer; preferably 10X to 100X of the thickness of the coating layer. The preferred thickness depends on the operating conditions of the catalyst, including the type of fuel, gas flow rate, preheating temperature, and the catalytic activity of the coating. He found that it is only necessary to apply a diffusion barrier coating on the downstream part of the catalyst (for example, 30¾ to 7050 of the total length, it can provide sufficient protection for the catalyst under certain conditions. Like the coating layer, the barrier layer can also It is applied by lacquering technology. The coating layer, catalyst and diffusion barrier layer can be applied to the entire surface of the catalyst carrier as described here, or can be applied only to the surface opposite to an uncoated surface. For example In the spiral corrugated structure mentioned above, it can be coated with only one side of the coating, catalyst and diffusion barrier layer. Then the processed corrugated structure is rolled into a complete ". On the side of the catalytic material The separator is covered with a material similar to the corrugated sheet, and rolled together with the corrugated sheet to form a single piece of media .. In any case, the single H surface with the catalyst placed on it will generate heat during the combustion process. *. The heat can be transferred to the flowing gas barrage, and transmitted to the adjacent non-catalytic surface through the mediator structure (and is relatively Λ 6 Π 6 (please read 1?

The heat will be passed from there to the unburned air vents passing along the surface. This allows the temperature of the catalyst surface in the catalyst structure to be controlled by intensive heat exchange, without the need for measures such as air dilution or external heat exchange structure. Road-like control capabilities may be highly desirable, for example When the preheating temperature of the inlet gas is high and the gas flow rate is unstable. The size and configuration of the media structure should be such that the average linear velocity of the gas passing through the axial channel of the media structure is within the entire catalyst structure. It is greater than about 0.2 m / s and less than 40 m / s. This lower limit is greater than the flame front velocity of methane, and the upper limit is a practical value for the currently commercially available carrier types. For fuels other than methane, there are two challenges. The average speed can be different from it. Method This method can use a variety of fuels, and can work in a wide range of operating conditions. Although the normal gaseous state (such as methane, ethane, and propane) is not Suitable as a fuel source for this method, most sulfonated fuels that can be vaporized at the process temperatures discussed below are also suitable. For example, the fuel can be liquid plaque or gas at room temperature and normal pressure. Examples include the low Molecular weight aliphatic hydrocarbons, as well as butane, pentane, hexane, heptane, octane; gasoline; aromatic hydrocarbons such as benzene, toluene, ethylbenzene, and xylene; naphtha; diesel and kerosene; mung engine fuel; Other intermediate preserves; heavier fuels (preferably hydrotreated to remove nitrogen and sulfur compounds); fermented oxygenated fuels, including formazan, ethylenzyme, isopropanol, butanol, etc .; and diethyl ether, Ethers such as ethylbenzene ether and MTBE. Other low-calorific gas such as city gas or synthetic gas can also be used as fuel. In typical cases, the amount of fuel mixed into the combustion air is the &lt;, ^ τ- line &lt; 81. 6. 10, 〇〇〇 Zhang (Η) 22 Ministry of Economic Affairs, the Central Bureau of Standards, Employee Xiao Zhong cooperation du printing ^ Λ β _Π6_ V. Description of the invention (21) The adiabatic combustion temperature is greater than the present invention The method is connected to the temperature mixture. The adiabatic combustion temperature is preferably higher than 800C, preferably above 1000¾. Non-gaseous fuel should at least partially vaporize before contacting the catalyst zone. Combustion air can be normal pressure or lower (0.25atiD) or compressed to a pressure of 35atB or higher. Stationary gas turbines (which can eventually use the liquefied gas produced by this method) generally work in a fan garden with a gauge pressure of 8 to 35 atB. Therefore, this method can work in the range of 0.25 to 35atB. It is best to be between 0 and 17atai. The fuel / air mixture delivered to the catalyst should be thoroughly mixed, and the gas inlet temperature can vary with the fuel used. This temperature can be achieved by preheating the gas by heat exchange or by adiabatically compressing the gas. This method uses a certain amount of catalytic material, which is placed on the catalyst carrier (preferably a metal carrier). The carrier has a junction-containing coating and has a low resistance to gas flow. The overall outlet temperature of the partially burned gas leaving the area containing the catalyst, as well as the wall temperature of the catalyst, will be significantly lower than the adiabatic or spontaneous combustion temperature of the gas. Generally speaking, the outlet temperature and the wall temperature are not higher than about 800¾, preferably not higher than 550D to 650C. In addition, the catalyst temperature should not exceed 1000Ό, preferably not more than 95010. These temperatures will depend on various factors, including the pressure of the bar, the partial pressure of the gas, and the heating value of the fuel. But the catalyst will partially vaporize the fuel, and its final temperature is limited to a certain value lower than its adiabatic combustion temperature. Examples These examples represent the preparation of catalysts within the scope of the invention and their use in the method of the invention. It also explains the comparison catalyst and comparison method.

By placing the catalyst in the combustion reactor and introducing fuel and air flow in "The tide on the media is LOT. Although these tide tests are conducted at atmospheric pressure, while others are conducted at a higher pressure. The temperature of the air gamble / air mixture increases at a constant rate. The temperature of the gas leaving the media and the catalyst are monitored. The temperature at several points in the middle. If the catalyst is active, when the temperature rises, on some stickies, the medium will begin to gasify the fuel, and the temperature of the gas at the outlet of the catalyst and the temperature in the middle can be seen to increase. .For comparison, the LOT takes the average temperature value of the preheating temperature and the self-limiting temperature value. After an appropriate (and constant) preheating temperature for the fuel and air mixture is selected, it is like the measurement of the LOT , By measuring the temperature at the same point in the catalyst and gas flow, The stability of the catalyst.

The final stone contains a thin coating of alumina of about 20% by weight. The alumina-coated stone is immersed in a Containing about 0.14 grams of platinum / gram of solution in HrPtC-Ib solution. The remaining solution is blown out with air, dried this stone and calcined at 500 · 〇. After being weighed, it is impregnated with platinum for more than two times.

Part B (Preparation of Rake Catalyst) Prepare a suspected medium and prepare Dong Qing stone with (washcoated) vaporized aluminum coating, like The above-mentioned roasting was carried out by dissolving 3 (: Sense) in two equivalents of hydrochloric acid and diluting to 0.042 g / ml to prepare a rake solution.

Description of the invention (24) The air is introduced into the air flow immediately upstream of the air mixer. The temperature of the gas before and after the medium is measured with a thermocouple with a ceramic sleeve suspended in the gas stream. The substrate temperature of the catalyst is measured by a thermocouple placed in a channel of a ceramic monolithic catalyst near the catalyst outlet. Heating the air to 550Ό increases the methane flow rate to 1.1 SLPM, and the corresponding fuel / air ratio is 0.0022. Monitor the substrate temperature. Step by step, increase the burnt-to-air ratio to 0.002, and record the substrate temperature for each fuel / air ratio. Some data are shown in Figure 3. When the fuel / air ratio is 0.010, the medium has sufficient activity to raise the substrate temperature to 740Ό. This value is close to the calculated adiabatic combustion temperature 760 of the mixture. Due to the increase in the burnt-to-air ratio, the substrate temperature is approximately equal to the adiabatic combustion temperature. This shows that all the fuel on the surface of platinum is burned. Rake catalyst Test the above-mentioned rake medium in the same way. Similarly, when the fuel / air ratio is increased, the substrate temperature increases and follows the calculated adiabatic combustion temperature. However, as shown in Fig. 3 (the burnt-to-air ratio is 0.013-0.020), the substrate temperature is kept at 800 1C. As shown in Figure 3, this embodiment illustrates a rake-containing combustion catalyst that limits the temperature of the catalyst combination to about 780X3. On the other hand, the temperature of the rake medium immediately follows the calculated adiabatic combustion temperature. Example 2 This example shows the measurement of the temperature when the gasified substance is converted into rake gold, and thus also shows the temperature limit of the catalyst substrate when methane is burned in excess air.

Description of the invention (25) 21.9 mg of the rake gasification powder test was loaded into a thermogravimetric analysis (TGA) device, and 40 ml / The most diverted dry air. The temperature of the sample was increased by 10t: / min, and the weight of the sample was continuously monitored to obtain the TGA curve as shown in the clock. At 795 &quot; C, the manganese oxide decomposes into a harrow and releases the oxygen generated when weightless. The measured weight loss of the sample is 2.74 mg, which is equivalent to 12.5¾ of the initial rake oxide sample weight. The theoretical weightlessness of the following formula is 13.1%. P d 0 ......-&gt; P d + at a heating rate of 5Ϊ: / min. After the TGA test, the conversion temperature of the rake gasification into the rake is 795 t: When a rake is used as the catalyst of Example 1 above, in air, the transition from rake oxide to rake measured by TGA at one atmosphere pressure occurs at approximately the substrate temperature as measured (approximately equal to 780 C) The same temperature is expected. The TGA test was repeated with a new sample of rake oxide, but the sample cavity was washed with pure gas. As shown in Fig. 4B, the measured transition temperature from the rake gasifier to the handle is 880C. At higher oxygen partial pressures, the transition point from rake oxide to rake will occur at a higher temperature. This example shows that the TGA made for the manganese oxide / barrel is a function of this specific oxygen partial pressure. Embodiment 3 This embodiment is divided into two parts.

A highly concentrated rake medium was prepared, and a 100cpsi, 50mm diameter and 50ma long cordierite sheet was coated with an alumina coating as described above. The thin coating was burned at 850 C for 10 hours. A PdCiU solution was prepared by dissolving PdCJli in two equivalents of hydrochloric acid. The final solution irrigation was 0.081 harrow / ¾ litre. This thin coating was immersed in this rake solution and the excess solution was blown off with air. Pass H \ S gas to this monolithic structure until all PdCJlvL is converted to PdS. Then burn the single piece in the air 508¾. Repeat the rake dipping process. Finally, burn for 10 hours at 850¾. The catalyst is placed in a test reaction device as described above. Insert thermocouples in a single hole at 10® », 25 faces, and 48am from the inlet. The hole is sealed with a ceramic binding agent, and the temperature of the substrate ceramic can be measured by the sample. The air of 1,000 SLPM and the natural gas of 40 SLPM flow through the catalyst. Heat the gas mixture of this feed to 300 °, and slowly increase the temperature. Monitor the activity of the medium as shown in circle 6. At 360t :, the medium is extinguished and its temperature rises above the gas temperature. At about 390TC, the substrate temperature from the gas outlet (10m to 48m from the outlet) is constant at about 800C. When the temperature of the gas inlet gas inlet is further increased, the substrate temperature is still limited to about 8001C. At 400 t :, based on this fuel / air ratio, the calculated adiabatic combustion temperature is about 1 240¾. This ionized catalyst did not cause the substrate temperature to increase to 1240 t: the fact is due to the strong temperature suppression performance of the rake.

The two sets of parameters for the catalyst: "Ignition and extinguishment temperature" (LOT) and the stability of the steady-state plaque were tested. It has 100 square holes per square inch and is composed of a single-H honeycomb structure composed of Dongdi stone ceramic. Coated with AJliO sol (Catabal Β), the single H was burned in air at 800 ° C. The generated single H contained 23.7 X A JL &gt; 0 ″, after which the single piece was immersed in a solution and dried , Burned in the air at 850t: 10 hours. The plum medium contains a 1.0X rake that accounts for the thin coating of the vaporized aluminum.

The dried foil H was burnt at 850t for 10 hours. The resulting roll of foil H is a single sheet having approximately 150 holes (opsi) per square inch. The coating applied on the thin layer of vaporized aluminum contains about 1.3 watts of Pd / cra2 and about 0.13 watts of Pt / cra2. Each catalyst was tested using the above-mentioned steady-state test method. The air flow rate is 1000 SLPM, but the feed / air ratio is 0.019 or 0.040. The warm-up level in each case was 500 T3. The temperature of the gas leaving the catalyst and the preheat temperature are measured separately. Comparing Figures 15A and 15B, both uses a fuel-air ratio of 0.019, and the post-catalyst temperature of the manganese catalyst is reduced to the level of 590 &quot; C, which is still decreasing at the end of the three-hour test. The rake / platinum catalyst shown in FIG. 15B of the present invention, by comparison, rose to the level described, and was substantially unchanged when the test ended after 1.7 hours. The rows of Figs. 16A and 16B show that the platinum-stabilized palladium catalyst is more stable when the fuel / air ratio is 0.040. In Figure 16B, the catalyst is still at a stable level of about 650 t :. Conversely, the stability of the unstabilized catalyst in Fig. 16A caused the temperature at the outlet to decrease to 600T3 in about 3 hours. This embodiment illustrates the difference between using a rake and using a catalyst with platinum simultaneously. The gold hurricane in this example is coated with vaporized aluminum.
