Abstract
The present invention discloses a hydrodesulfurization catalyst for fraction oil and a preparing method thereof. The catalyst comprises alumina or silicon-containing alumina as carriers and Mo-Ni as active compositions, and a phosphorus auxiliary agent is added. Alkaline Mo-Ni-P co-soaking liquid is used for the sectional co-soaking of the carriers, so that metal distribution on the catalyst becomes uniform, and the activity of the catalyst, particularly the hydrodesulfurization activity on fraction oil, is obviously enhanced.
Description
The present invention relates to a kind of catalyst for hydrodesulfurizationfraction fraction oil and preparation method thereof.
Typical Hydrobon catalyst is a carrier with aluminum oxide or siliceous aluminum oxide often, is active ingredient with VIII family and group vib metallic element.In order to improve activity of such catalysts and stability, often adopt multiple improved method, as carrier being carried out modification modulation carrier surface character, interpolation auxiliary agent and optimizing the preparation method and improve the dispersing property of active ingredient on carrier etc.Auxiliary agent commonly used has P, F, B, Ti, Zr, Fe, Mg, Cr etc., at present existing manyly prepare the patent disclosure of catalyzer about acid Mo-Ni-P co-impregnated solution (for example U.S. Pat 4,568,449), but the patent for preparing catalyzer for the Mo-Ni-P co-impregnated solution of alkalescence does not also have, and traditional acid Mo-Ni-P co-impregnated solution prepares catalyzer and has following several point defects:
1) be active ingredient with Mo, Ni, adding P is the Mo-Ni-P catalyzer of auxiliary agent, has only P
2O
5Its hydrodesulfurization activity was just high when content was relatively low, and tart Mo-Ni-P co-impregnated solution, P content then is difficult to make when low stablizes the Mo-Ni-P steeping fluid, and the increase of P content causes steeping fluid viscosity big, moist catalysis behind dipping bonding easily is agglomerating, cause metal-salt in roasting process, to decompose not exclusively, thus the infringement catalyst activity.
2) because tart Mo-Ni-P co-impregnated solution viscosity is big, influential to the dispersing property of active ingredient on carrier, can not make active ingredient high dispersing on carrier, influential to activity of such catalysts.
The object of the invention provides a kind of catalyst for hydrodesulfurizationfraction fraction oil and preparation method thereof, adopts the hydrodesulfurization activity of the catalyzer of this method preparation to be significantly improved.
The composition and the physico-chemical property of catalyzer of the present invention are as follows:
With aluminum oxide or siliceous aluminum oxide is carrier, is active ingredient with Mo, Ni, and for helping catalyst component, by catalyst weight, each component concentration is respectively MoO with P
320～30%, NiO2～7%, P

51～3.5%; Described active ingredient and to help catalyst component be that the mode of alkaline Mo-Ni-P co-impregnated solution by step impregnation loaded on the support of the catalyst, promptly the usefulness alkaline co-impregnated solution that contains Mo, Ni, P carries out at least double-steeping to support active ingredient and to help catalyst component to support of the catalyst; 0.25～0.40 milliliter/gram of catalyzer pore volume, 120～200 meters of specific surface areas
2/ gram.
Described step impregnation number of times at least 2 times generally is 2-4 time, preferably 2 times.
Preparation of catalysts method of the present invention is as follows:
Catalyzer of the present invention is a carrier with aluminum oxide or siliceous aluminum oxide, is active ingredient with Mo, Ni, adds phosphate builder, and (proportion is preferably 0.910～0.940g/cm with ammoniacal liquor
3) make stable Mo-Ni-P alkalescence co-impregnated solution, with the mode impregnated carrier (promptly step by step altogether soak) of above-mentioned co-impregnated solution to be no less than secondary, moist catalysis was through 90～150 ℃ of dryings 2～6 hours, and 450～550 ℃ of roastings made described catalyzer in 2～5 hours.
It is secondary at least that described substep soaks number of times altogether, generally is 2～4 times, preferably adopts 2 catalyst-loaded active ingredients of the saturated mode that sprays and helps catalyst component, all needs drying and roasting after spraying at every turn.
The preparation of described aluminum oxide or siliceous alumina supporter can be that aluminum oxide is added peptizing agent and extrusion aid or silicon sol, mixes to be extruded into bar shaped or to drip globulate after pinching, and through 90～150 ℃ of dryings 2～8 hours, 500～650 ℃ of roastings made in 2～5 hours.
Described aluminum oxide can be the macropore aluminium hydrate powder that adopts aluminum chloride-ammoniacal liquor method, Tai-Ace S 150-sodium metaaluminate method, carborization and alkyl aluminum hydrolysis method to make.
The compound method of Mo-Ni-P alkalescence co-impregnated solution is: molybdenum compound, nickel compound and phosphorus compound are added airtight stirring and dissolving obtains stable Mo-Ni-P alkalescence co-impregnated solution in the container (as Erlenmeyer flask) that the alkaline medium aqueous solution (as ammoniacal liquor) is housed.
Above-mentioned molybdenum compound is an ammonium molybdate, and nickel compound is a nickelous nitrate, and phosphorus compound is a phosphoric acid, and alkaline medium is that (proportion is preferably 0.910-0.940g/cm to ammoniacal liquor
3).
