Application of Suspended Catalysts to the Catalytic Cracking of Vacuum Gas Oil

摘要

The results of experimental studies on the application of finely dispersed catalytic compositions prepared based on the aqueous solutions of sodium silicate and Al_2(SO_4)3 and a suspension of zeolite NaY to the process of the catalytic cracking of the vacuum gas oil fractions of petroleum are given. It was found that the degree of conversion of a raw material into a fraction of motor fuels at a temperature of 450℃ and a feed space velocity of 4.0 h~(-1) varied from 31.8 to 53.6% depending on the catalytic composition used, or it was higher than 90% upon the complete conversion with the recycling of the residue.
