CATALYTIC CRACKING GASOLINE REFINING PROCESS Russian patent published in 2005 - IPC

Abstract RU 2258732 C1

FIELD: petroleum processing.

SUBSTANCE: catalytic cracking gasoline is first subjected to hydrofining and then separated into light [boiling start -110(150)°C] and heavy [110(150)°C-dry point] fractions. The latter is divided into two streams, one being returned into hydrofining stage to be combined with raw gasoline and the other being compounded with light hydrofined fraction and withdrawn from system as motor gasoline component (sulfur level 0.04-0.1%). Process allows preferably of catalytic cracking gasoline with sulfur level below 0.1% (lack of mercaptan sulfur) with minimum loss in octane number in refined gasoline.

EFFECT: enhanced process efficiency.
