Bimetallic Sulfur-Reducing Additives Based on Al–MCM-41 Structured Aluminosilicate for Cracking Catalysts

Аннотация

An ordered mesoporous aluminosilicate of the Al–MCM-41 type has been studied as a component of additives for of petroleum feedstock cracking catalysts. The influence of the nature of the modifying material and its concentration on the activity of the additive has been investigated. It has been shown that the use of bimetallic additives on the basis of ordered mesoporous aluminosilicate makes it possible to reduce the sulfur content in liquid cracking products of vacuum gas oil by 37% more effectively in comparison with that for an additive-free industrial catalyst.
