Catalytic cracking of hydrotreated vacuum gas oil over a zeolite-containing catalyst modified with nickel and cobalt nanoparticles

Abstract

The effect of the concentration of nickel and cobalt precursors on the catalytic cracking performance has been studied. A FTIR study of the catalyst surface after cracking in the presence of nickel and cobalt precursors has been conducted. It has been shown that the surface of industrial catalysts can be in situ modified with compounds of Group VIII metals in the acid-catalyzed conversion of a vacuum distillate.
