Abstract
The invention discloses a catalyst for low quality heavy oil or residue suspended bed hydrocracking and preparation method belongs to oil process technology area. The catalyst is a sulfurization form transition metal nm particle that existing in the reversed phase micelle colloidal solution, the disperse medium of reversed phase micelle colloidal solution is organic phase, the disperse phase is a water phase parceled by surface activity, sulfurization form transition metal nm particle steady consist in the water phase. The transition metal active ingredient in disperse phase elect as Cu,Mn,Fe,Co,Ni,Cr,Mo,W,Zn,Sn,Pb elementary sulfurization form particle and so on, the grain size between 1nm-1000um. This catalyst can uniformly dispersed in the low quality heavy oil,residue, and under the certain reaction temperature and hydrogen aura, the low quality heavy oil or residue containing catalyst through suspended bed hydrocracking translated into light oil. On the premise of reducing catalyst enter quantity, the invention effectively controlled the coking products in heavy oil or residue suspended bed hydrocracking process, improved the yield of light oil.
Description
Technical field:
The present invention relates to the Catalysts and its preparation method of a kind of inferior heavy oil, dreg-oil suspension bed hydrogenation cracking, belong to PETROLEUM PROCESSING and petrochemical technology field.
Background technology:
At present, it is heavy that the crude oil of domestic exploitation becomes day by day, and the heavy crude of import and residual oil amount also constantly increase, and market is increasing to the demand of light-end products, therefore people more and more pay attention to heavy oil lighting technology, and the heavy oil floating bed hydrocracking technology is exactly one of technology that receives much concern.Because the heavy oil floating bed hydrocracking technology has also generated a large amount of coke at inside reactor when guaranteeing higher light-end products yield, influenced the long-term operation of reactor.So the green coke problem in the heavy oil floating bed hydrogenation technology becomes the major issue that presses for solution, the new catalyst of researching and developing efficiently, be suitable for the heavy oil floating bed hydrogenation process characteristic more and more causes the great attention on oil refining circle.
At present, the water-soluble catalyst typical technology that is used for heavy oil floating bed hydrogenation has Exxon company to make catalyst with phosphomolybdic acid and Chevron company makes catalyst with ammonium molybdate.In the research of oil-soluble catalyst, there is United States Patent (USP) 4579838 to announce, obtains oil-soluble di-t-butyl chromate, it is mixed with part heavy oil, in the presence of hydrogen sulfide gas, add hot mixt then, obtain catalyst with chromium oxide and alcohol reaction.Heating condition is 370~427 ℃, 0.7~14MPa, and chromium content is 0.1~2.0m% in the gained slurry catalyst.This catalyst is used for the heavily floating bed hydrogenation of Arabic decompression residuum, reaction pressure 14.4MPa, 443 ℃ of reactions down when the addition of catalyst is 350 μ g/g, are 84.6m% greater than 524 ℃ of cut conversion ratios, coking yield is 1.43m%.Adopt Fe (CO) in the United States Patent (USP) 5578197
5With the 2 ethyl hexanoic acid molybdenum be catalyst, is raw material to contain 60m% greater than 504 ℃ residual oil, the catalyst addition is 5000 μ g/g, and add diluent in 2: 1 ratio, on autoclave, test 430 ℃ of reaction temperatures, reaction pressure 10.0MPa, 105 minutes reaction time was 27.0m% greater than 504 ℃ liquid yields, and coke is 3.8m%.When United States Patent (USP) 4125455 adopted molybdenum caprylates to be catalyst, as metal addition 590 μ g/g, the reaction time was when being 8 hours, was 80.0m% greater than the conversion ratio of 454 ℃ of cuts.One or more metals in the Chinese patent 00110711.9 application element periodic table in group vib, VIIB family and the group VIII with contain the formed complex compound of heteroatomic heterocycle sulfo group compound as catalyst, wherein metallic element includes iron, cobalt, nickel, chromium, molybdenum, tungsten; Chinese patent 01109276.9 is used the aqueous solution of iron, nickel, cobalt, molybdenum as catalyst.Still there are some shortcomings in above-mentioned catalyst, as catalyst cost an arm and a leg, the active component addition is big, dispersion effect in feedstock oil is poor, degree is high and press down burnt weak effect or the like fully in sulfuration.
Summary of the invention:
The objective of the invention is in order to develop a kind of reversed phase micelle nano catalyst that is used for dreg-oil suspension bed hydrogenation cracking and preparation method thereof.This catalyst is used for the heavy oil floating bed hydrocracking technical process, in raw material, highly evenly disperse under the situation that can make catalytic active component guarantee that higher sulfuration spends fully, can suppress the coking of reactor and boiler tube in the heavy oil floating bed hydrogenation process effectively, solve the long-term operation problem of heavy oil floating bed hydrocracking technology.
The object of the present invention is achieved like this, the catalyst that is provided is a kind of reversed phase micelle solution, its composition comprises: as the organic facies of decentralized medium, decentralized photo is the water by the surfactant parcel, active component is a kind of sulphided state transition metal sodium rice particle, and stable existence is in the aqueous phase of reversed phase micelle colloidal solution.Specifically consisting of of this reversed phase micelle nano catalyst system: the content of organic facies is 50~90m%, and water content is 0.1~30m%, and the content of transition metal active component is 8~45% in the aqueous solution, and the content of surfactant is 0.01~10.0m%.
Transition metal active component in the decentralized photo is the sulfide of one or more transition metals among group VIII, VIB and the VIIB in the periodic table of elements, the sulphided state particle of elements such as Cu, Mn, Fe, Co, Ni, Cr, Mo, W, Zn, Sn or Pb preferably, particle diameter is between 1nm~1000 μ m.It is in the reversed phase micelle colloidal dispersion of decentralized medium that active metal component is evenly distributed on the organic facies.The organic facies decentralized photo of this reversed phase micelle colloidal dispersion is for comprising C
