CATALYTIC CRACKING OF VACUUM GASOIL IN THE PRESENCE OF ACTIVATING ADDITIVES.

In order to determine the influence of the aggregation resistance of the feedstock in catalytic cracking on the material balance of this process and on the quality of the products, a series of studies was conducted on the cracking of vacuum gasoil from West Siberian crude. As additives an extract from selective treatment of the lube cut, and also tars obtained in thermal cracking of residual and distillate stocks from the same crude were used. The catalytic cracking was performed in a single-pass laboratory flow unit with mechanical mixing of a bed of a microbead zeolitic catalyst.
