International Classification:

C10G 69/04

US Classification:

208 55, 208 50, 208 52 R, 208 52 CT, 208 54, 208 67, 208 73, 208 76, 208125, 208131, 208132, 208208 R

Abstract:

The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt %, based on the hydrocarbon feed. The hydrocarbon feed is treated in a two-step process. The first is thermal conversion and the second is catalytic cracking of the products of the thermal conversion. The present invention results in a process for increasing the distillate production from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step.

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.
