Description

A kind of Hydrobon catalyst compositions and preparation method thereof

Technical field

The present invention relates to a kind of Hydrobon catalyst compositions and preparation method thereof, the most highly active body phase hydrotreatment catalyst composition and preparation method thereof.

Background technology

At present the most worldwide, crude oil heaviness increasingly and in poor quality, the sustainable development of World Economics and the increasingly stringent of environmental regulation, need to produce a large amount of light clean fuel in addition.Exploitation and to use super-low sulfur be even to clean the trend that fuel develops in the range of the world today without sulfur vapour, diesel oil.Traditional Hydrobon catalyst is used such as to improve reaction temperature, hydrogen dividing potential drop by increasing reaction severity or reduce reaction velocity etc., the deep desulfuration even ultra-deep desulfurization of diesel oil can also be realized, but the rising of reaction temperature can cause the variation of product colour and catalyst life to shorten, and reduces air speed and then means the minimizing for the treatment of capacity.For existing hydrogenation plant, its design pressure is the most fixing, and the amplitude improving hydrogen dividing potential drop is limited.Therefore, current is one of the important means of deep desulfuration by using the catalyst of more high desulfurization activity.

Containing various structures and the sulfur-containing compound of different molecular weight in petroleum distillate, but at ultra-deep desulfurization stage (sulfur content is less than 50 g/g), mainly removing 4, the sulfur-containing compound of the substituted bases such as 6-dimethyl Dibenzothiophene class.Owing to the methyl of sulphur atom next-door neighbour makes to create between sulphur atom and the active center of catalyst sterically hindered, the active center of the most accessible reaction of sulphur atom, thus result in reaction rate and significantly decline.

Conventional load type hydrogenation catalyst is limited by carrier hole structure, active metal load capacity is usually no more than 30wt%, the active center quantity that loaded catalyst can be provided by is limited, although the quantity in active center and type distribution can be optimized adjustment, but owing to the limit bottleneck of active center quantity cannot be broken through, increase substantially the limited space of hydrogenation activity, be difficult to the demand meeting refinery to manufacturing country V diesel product.Hydrogenation catalyst major part prepared by body phase method is made up of active metal component, the restriction of tenor can be broken away from, can any ratio of each active component in regulating catalyst, improve the Hydrogenation of catalyst, owing to bulk phase catalyst has the hydrogenation activity of excellence, can be under conditions of not improving device reaction severity, being directly produced the product without sulfur diesel meeting state V standard, original device is without transformation, it is possible to improve the treating capacity of device, reduce the production cost of refinery, it is achieved energy efficiency.

Although active metallic content is high in body phase hydrogenation catalyst, but by mechanical strength, the restriction of the aspects such as active metal easily gathering, need to add a certain amount of adhesive component, generally meet the requirement of mechanical strength, the addition of binding agent will be at more than 30wt%, the most, the most not only reduce the consumption of active metal, in making again amount of activated metal entrance body mutually, make it can not become hydrogenation sites, there is the problem that active metal utilization rate is low, simultaneously, the distribution making different hydrogenation active metals is not easily controlled, thus affect the distribution of different hydrogenation active metals.Therefore, for body phase hydrogenation catalyst, there is the distribution of good hydrogenation active metals, there is mating reaction between suitable hydrogenation active metals component, there is high catalyst surface active bit density, there is high active metal utilization rate, the activity of catalyst can be significantly improved.

CN1951561A discloses the method using co-precipitation to prepare hydrogenation catalyst, and catalyst uses active metal Ni, W component to generate Ni with precipitant co-precipitation_xW_yO_zComposite oxides precursor, in above process, can add aluminum salt solution, it is also possible to be directly added into aluminium hydroxide after plastic, then with MoO₃Making beating mixing, filtration, molding, activation are final catalyst.Bulk phase catalyst prepared by the method reaches to meet the use of mechanical strength when requiring, its surface activity bit density is relatively low, it is impossible to give full play to the advantage of high-load active metal component, reduces the utilization rate of active metal, adds the preparation cost of catalyst.

CN101306374A discloses a kind of hydrogenating catalyst composition, this catalyst is prepared by coprecipitation method, the compound of at least one metal component of group VIII, the compound of at least two metal component of group VIB, organic additive and water are mixed with mixed liquor, the pH using acid or alkali to adjust mixed liquor is 7～11, described mixed liquor is placed in reactor, react 1～24 hour under the airtight condition of room temperature to 250 DEG C, filter afterwards and be dried.The catalyst of the method gained is without high-temperature roasting, containing organic additive in final catalyst, the mechanical strength of catalyst to be made meets use requirement, needs to add more adhesive component, so can affect the distribution of different hydrogenation active metals, make catalyst surface active reduce.

CN101255356A discloses the preparation method of a kind of unsupported catalyst, it is to use urea melting reaction technology, the VIIIth race and group VIB active metal precursor will be contained and carbamide will mix and is incorporated under urea melting state reaction, remove unnecessary carbamide, obtain catalyst particles, can be shaped by adding binding agent.In the method, carbamide adds as precipitant, need after reaction to add the carbamide that heat extraction is unnecessary, being subsequently adding binding agent to be shaped, such the method yet suffers from the addition of binding agent and makes the skewness of different hydrogenation active metals, the low density problem of catalyst surface active position simultaneously.

Hydrogenation catalyst prepared by body phase method, its hydrogenation sites be reactant molecule can be close catalyst channel surfaces on, although this type of catalyst activity tenor is higher, but not all active metal can become hydrogenation sites, therefore, how to make more active metal be distributed in channel surfaces and form hydrogenation sites, improve the active center density on bulk phase catalyst surface, the utilization rate improving hydrogenation active metals component is the most important research topic.

Body phase hydrogenation catalyst disclosed in CN102049265A, ammonium hydrogen carbonate is added during coprecipitated, body phase hydrogenation catalyst disclosed in CN102451703A, carbon dioxide is added during coprecipitated, generate carbonate or bicarbonate, said method is all to utilize it to release a certain amount of gas in roasting process, under the percussion of gas, increase the pore volume of catalyst, specific surface area, more metal active position is made to be exposed to the surface of catalyst, but this kind of method can make cell channels collapse, pore size distribution disperse, mechanical strength reduces, and cause active metal localized clusters, the metal active position come out is limited.

Under distillate ultra-deep hydrodesulfuration reaction environment, present in distillate, nitrogen-containing organic compound produces obvious inhibitory action to hydrodesulfurization reaction, hydrodesulfurization activity increases along with the nitrogen content in raw material and reduces, this is because there is competitive Adsorption on catalyst activity position in nitrogen-containing compound and sulfide in distillate, the absorbability of nitride is stronger, occupy the active sites on catalyst, sulfide is made to be difficult to close, inhibit hydrodesulfurization reaction, so when processing the high heavy diesel of nitrogen content and producing super-low sulfur product, catalyst needs the hydrodenitrogenationactivity activity with excellence, the hydrodenitrogenationactivity activity of catalyst improves, after nitrogen content reduces, reduce with the nitride of sulfide generation competitive Adsorption, sulfide is easier to, adsorb the most more on catalyst activity position, promote hydrodesulfurization reaction.Therefore the hydrodenitrogenationactivity activity improving catalyst has extremely important effect to the ultra-deep hydrodesulfuration activity improving bulk phase catalyst.

The petroleum refining industry of 21st century must comply with the strategy of sustainable development, it is necessary to pay attention to economic benefit, protection environment and the principle economized on resources simultaneously.Therefore, the preparation method using non-environmental-pollution produces bulk phase catalyst and becomes more important.Existing coprecipitation method prepares catalyst technology, is used mostly NH₃·H₂O is as precipitant, and these are a large amount of containing ammonia, the waste water of nitrogen, to environment by producing.

Coprecipitation method prepares bulk phase catalyst technology, use different coprecipitation mode, Gelation Conditions etc., all can to active metallic content on channel surfaces in catalyst and between active center density, the distribution of different hydrogenation active metals and different hydrogenation active metals interaction relationship have a great impact.The coprecipitation method of above-mentioned employing can make the distribution of different hydrogenation active metals be not easily controlled, thus affect the distribution of different hydrogenation active metals, reduce the effect of cooperating between active metal, simultaneously, in catalyst, table phase active metallic content is less and active center density is relatively low, finally affects the ultra-deep hydrodesulfuration performance of catalyst.Therefore, how to regulate and control the distribution of hydrogenation active metals, make to have between hydrogenation active metals component suitable mating reaction, how to increase table phase active metallic content and active center density in catalyst, improve the utilization rate of hydrogenation active metals component, be the key improving body phase Hydrobon catalyst Hydrogenation.
