Reversed phase micelle nano catalyst for dreg-oil suspension bed hydrogenation cracking and preparing method

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: [0001] The invention relates to a catalyst for hydrocracking of low-quality heavy oil and residual oil suspended bed and a preparation method thereof, belonging to the technical fields of petroleum processing and petrochemical industry. Background technique: [0002] At present, the crude oil mined domestically is becoming heavier and the amount of imported heavy crude oil and residual oil is also increasing, while the market demand for light oil products is increasing. Therefore, people pay more and more attention to the technology of lightening heavy oil. Suspension bed hydrocracking technology for heavy oil is one of the technologies that has attracted much attention. Because the heavy oil suspended bed hydrocracking technology ensures a high yield of light oil, a large amount of coke is also generated inside the reactor, which affects the long-term operation of the reactor. Therefore, the problem of coke formation in the heavy oil suspension bed hydroge...
