Sulfur-reduction additives based on ordered hexagonal mesoporous silica in the catalytic cracking of vacuum gas oil

Resumo

Materials of the composition of La/hexagonal mesoporous silica/γ–Al₂O₃ with different contents of components in the carrier have been synthesized and tested as sulfur-reduction additives to the commercial zeolite-containing cracking catalyst. It has been shown that the sulfur content in liquid products decreases by 5–32% when vacuum gas oil is cracked at a temperature of 500°C in the presence of additives in the amount of 10 wt % relative to the weight of the catalyst.
