Description
The present invention relates to a catalyst for steam reforming of hydrocarbons, and more particularly to a monolith catalyst for steam reforming of hydrocarbons in which a transition metal is dispersed in a carbon-based metal support to prepare wash coats and the honeycomb support is coated.
In the atmosphere in accordance with the use of fossil fuels, the greenhouse gas carbon dioxide (CO 2), methane (CH 4), hydrogen sulfide (H 2 S), carbonyl sulfide (COS) and so on by acid gas concentration is increasing, global warming resulting problem . To solve this problem, electricity generation using fuel cells is a representative technology for reducing greenhouse gas emissions by increasing conversion efficiency, and uses hydrogen and syngas produced by reforming hydrocarbons.
The production of hydrogen and synthesis gas through reforming of hydrocarbons, including fossil fuels, biomass tar, DME, alcohol, Volatile Organic Compounds (VOCs), etc., do. The catalyst used here is mainly prepared by dispersing metal ions on activated alumina, silica, or metal oxide support having a large surface area. However, existing catalysts have a problem that they are easily inactivated by coking of carbon during the reaction.
Of the fixed bed reactors most commonly used for gasification of solid fuels, upflow gasifiers have advantages of low initial investment, availability of fuel with high moisture content and simple process, / Nm < 3 > of hydrocarbons are generated, which may cause adverse effects on the downstream equipment. Therefore, in order to utilize the syngas, purification and removal processes are required. For this purpose, a steam reforming process using a transition metal, particularly nickel (Ni), which is a catalyst of a hydrocarbon decomposition process, is mainly used, and a catalyst metal support capable of evenly dispersing the catalyst in order to increase the efficiency of the catalyst is needed. Also, since the gaseous catalytic reaction occurs on the surface of the solid catalyst, the wider the surface area, the more the reaction by the active substance spreading on the surface increases. That is, when the surface area of the catalyst is increased to maximize the active site, the catalytic activity is increased. At this time, the catalyst support does not exhibit catalytic activity, but serves to maintain and improve the stability and durability of the prepared catalyst.
When a low-grade coal with ion-exchange ability is used as a metal carrier and the transition metal ions are dispersed in a low-grade coal through ion exchange, the catalyst can be dispersed in a very small and even distribution , The related expression is as follows.
2 (-COOH) + Ni 2+ - (COO) 2 Ni + H 2
As such, the use of low grade coal can disperse small and even metal ions more efficiently than with a conventional metal carrier. However, at high temperatures, low grade coal is involved in the steam reforming reaction and losses occur. Therefore, high-grade coal with lower reactivity than low-grade coal can be used at high temperatures.
Japanese Patent Application Laid-Open No. 2006-328268 discloses a biomass gasification method and system using a metal support carrier, and a method and system for recovering metal particles from the metal carrier. In other words, tar was dispersed in low-grade coal by using transition metal as a catalyst for steam reforming with beneficial gas (H 2 + CO) in biodegradation and gasification process. However, when low grade coal is used as a metal support, low grade coal is consumed in the steam reforming reaction at a certain temperature or higher in the steam reforming process.
Korean Patent No. 0542911 relates to a low-pressure catalyst for gasoline reforming used in a fuel cell vehicle, wherein the surface of the ceramic honeycomb carrier is wash-coated with submicron alumina or a precursor thereof to sufficiently enlarge the effective surface area and amount of the catalyst Pressure catalyst for gasoline reforming of a fuel cell vehicle produced by supporting a transition metal catalyst powder. However, this is a catalyst using alumina, which is easily inactivated by coking of carbon during the reaction.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.
In one aspect, the present invention provides a honeycomb-shaped support having a gas flow channel formed therein; And a wash coat layer formed on the honeycomb-shaped support, wherein the wash coat layer has a particle diameter of the constituent particles of 1 占 퐉 to 50 占 퐉; And a transition metal ion or a transition metal mixture ion dispersed in the metal support. The present invention also relates to a monolith catalyst for steam reforming of hydrocarbons.
Hydrocarbon steam reforming is a method of synthesizing hydrogen, carbon monoxide or synthesis gas by reacting hydrocarbons and water vapor at a high temperature in the presence of a catalyst. Generally, carbon monoxide, carbon dioxide and hydrogen are produced by the reaction represented by the following formula (1). The present invention relates to a monolith catalyst for reforming hydrocarbon steam, wherein the monolith catalyst comprises a honeycomb type support having a gas flow channel formed therein and a wash coat layer formed on the honeycomb type support.
The honeycomb-shaped substrate of the present invention has a plurality of parallel longitudinal gas flow channels having a honeycomb structure. FIG. 1 is a schematic illustration of a honeycomb-shaped support of the present invention, wherein the honeycomb-shaped support has gas flow channels of 10 to 1,000 cpsi (cells per square inch), and preferably 200 to 500 cpsi . FIG. 2 shows the inside of the monolith catalyst of the present invention schematically. The
The washcoat layer of the present invention is coated on the honeycomb-shaped support in the form of a thin film, and is composed of a catalyst composition for reforming hydrocarbon steam. The composition includes a carbon-based metal support having particle diameters of 1 to 50 占 퐉, and transition metal ions or transition metal compound ions dispersed in the metal support. Wherein the carbon-based metal support is a low grade coal comprising peat, argon or lignite; High grade coal, including bituminous coal, bituminous coal or anthracite; But are not limited to, one or more selected from the group of advanced carbon sources including graphite, active carbon, and carbon black.
The hydrocarbon steam reforming reaction of the present invention is carried out at 300 to 800 캜. In the case where a conventional low grade coal is used as a catalyst support and a catalyst is produced, the catalyst is operated at a temperature of 400 ° C. to 600 ° C. since it is consumed in the steam reforming process in many cases at a temperature of 400 ° C. or more in the steam reforming reaction (See Takayuki Takarada, Yasukastu Tamei and Akira Tomota, Reactivities of 34 coal under steam gasification, Fuel, 1985, 64, 1438, etc.). Therefore, the hydrocarbon reforming performed at 400 ° C to 600 ° C using the catalyst of the present invention can use low grade coal as the carbon-based metal support. On the other hand, a monolith catalyst using high grade coal, graphite, active carbon, carbon black or the like, which is an advanced carbon source of the present invention, as a metal support is preferable at a high temperature of 600 ° C or higher. When the above-described advanced carbon source is used as the metal support, the hydrocarbon steam reforming reaction can be carried out at a high temperature, so that the reforming reaction of methane, ethane, propane, butane and other aliphatic and aromatic hydrocarbons Lt; / RTI >
The wash coat comprising the carbon-based metal support of the present invention, particularly the wash coat using coal, is advantageous for the dispersion of the metal ion or metal mixture, which is a catalytically active substance, through micropores, and exhibits catalytic activity by itself. In addition, the spent catalyst can be energized, the recovery of the metal ion or the metal mixture after use of the catalyst is easy, and the catalyst deactivation due to carbon deposition during the hydrocarbon reforming can be prevented. In addition, by coating the honeycomb-shaped support in the form of a wash coat, the contact area with the reactant can be maximized to increase the catalytic activity efficiency of the hydrocarbon steam reforming reaction. In the monolith catalyst of the present invention, the carbon-based metal support is required to be atomized to increase the mechanical strength of the washcoat. In one embodiment of the present invention, the average particle diameter of the above-mentioned atomized and ground carbon-based metal support particles is not particularly limited, but is 1 탆 to 50 탆. When the average particle size of the atomized carbon-based metal support is 1 탆 or less or 50 탆 or more, the adhesion to the honeycomb type support or the mechanical strength of the coated wash coat is reduced. Further, the amount of the catalyst that can be coated on the honeycomb type support of the present invention is limited by the coating thickness. If the coating is thick, the channel will be constrained and the pressure loss will be higher when used. Thick coatings can also cause catalyst adhesion problems.
In the case of low-grade coal, especially in the above-mentioned atomized pulverized carbon-based metal carrier, it is possible to disperse the metal without pretreatment because of the existence of an ion exchange functional group in the coal, and other high grade coal such as high grade coal, graphite, it is effective to perform ion exchange by generating a functional group capable of ion exchange through chemical pretreatment for active carbon or carbon black. FIG. 3 is a graph showing the results of a metal-coal washcoat composition prepared by acid treatment of bituminous coal as a high grade coal at 2O < 0 > HNO3 solution for 3 hours at 60 & TEM photograph. It can be seen from the TEM photograph that the metal is evenly dispersed in the bituminous coal. In one embodiment of the present invention, the process for the chemical pretreatment is an acid treatment, wherein the acid treatment includes but is not limited to HCl, H 2 SO 4 , HNO 3 , H 3 PO 4, and H 2 CO 3 , And the amount of ion-exchangeable functional groups is changed depending on acid treatment conditions. The conditions may vary depending on the type or amount of the metal to be ion-exchanged and may be, for example, 1 to 20 hours in an aqueous HNO 3 solution of 1 M to 3 M at a temperature of 60 ° C, but are not limited thereto. A transition metal or a transition metal mixture is dispersed in the acid-treated carbon-based metal support through an ion exchange reaction to prepare a washcoat composition. In one embodiment of the present invention, the transition metal is at least one selected from the group consisting of nickel (Ni), iron (Fe), copper (Cu), chromium (Cr) and zinc (Zn) Is a mixture of at least one selected from the group consisting of potassium (K), sodium (Na), calcium (Ca) and magnesium (Mg) The transition metal or transition metal mixture is contained in an amount of 3 to 30 weight% with respect to the carbon-based metal support.
