Effect of WC/Ni–Cr additive on changes in the composition of an atmospheric residue in the course of cracking

Abstract The paper presents the results of investigation of changes in the composition of hydrocarbons and sulfur-containing compounds of an atmospheric residue in the course of cracking in the presence of a tungsten carbide–nickel–chromium (WC/Ni–Cr) catalytic additive and without it. The cracking...
