Abstract

The invention discloses a catalyst of hydrogenated and cracked inferior heavy oil and residual oil suspending bed, which is characterized by the following: adopting 75-98m% water as dispersing dielectric; selecting 2-25m% transition sulfate metal (Fe, Co, Ni, Cr, Cu, Mn, Mo, W) as dispersing phase; controlling grain size between 0.1-100um; hydrogenating and cracking heavy oil into light oil.

Description

Technical field: [0001] The invention relates to a catalyst for hydrocracking of 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] With the increasingly heavy crude oil extracted and the increasing demand for light oil products in the market, people pay more and more attention to the technology of lightening heavy oil. Suspension bed hydrogenation technology of 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 hydrogenation process has become an important problem that needs to be solved urgently. It is urgent to research and develop a...
