Abstract
This invention relates to a process for the selective conversion of vacuum gas oil. The vacuum gas oil is treated in a two step process. The first is thermal conversion and the second is catalytic cracking of the products of thermal conversion. The product slate can be varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step. The combined products from thermal and catalytic cracking are separated in a divided wall fractionator.
