Method for producing a low-sulfur catalytic cracking gasoline desulfurization using the additional function fluid catalytic cracking catalyst method of manufacturing the same, and desulfurization function adds fluid catalytic cracking catalyst

摘要

In the process of producing the catalytic cracking gasoline by decomposition of heavy oil can be efficiently reduced the sulfur content of the catalytically cracked gasoline, and porous inorganic (b) zeolite and non-zeolite was (a) alumina-coated The content and (b) alumina 30 to 70 wt% and 5 to 40 wt% zeolite was coated with (a) alumina or is a catalyst formed by supporting a vanadium carrier comprising a clay mineral and / or oxides It will carry a vanadium carrier which is supported phosphorus and manganese and / or vanadium at least a carrier containing a porous inorganic oxide the ratio of vanadium concentration of before and after grinding, or the two or more catalysts phosphorus to form a complex ion and manganese and / or vanadium in carrying solution when it becomes Te, carrying the phosphorus and manganese and / or vanadium, transmission of the reverse osmosis membrane of the complex ion, the reverse osmosis membrane of vanadium and to provide a catalyst is 25 wt% or less of the amount of transmitted.
