Integrated process combining catalytic cracking with hydrotreating
Abstract
Abstract AN INTEGRATED PROCESS IS DISCLOSED, COMPRISING CATALYTICALLY CRACKING A HYDROCARBON FEEDSTOCK IN A CATALYTIC CRACKING ZONE; PASSING THE GAS OIL PORTION OF THE EFFLUENT FROM THE CATALYTIC CRACKING ZONE TO A HYDROTREATING ZONE; REGENERATING THE CATALYTIC CRACKING CATALYST USED IN THE CATALYTIC CRACKING ZONE BY BURNING CARBONACEOUS DEPOSITS THEREFROM, THEREBY PRODUCING HEAT; HEATING WATER TO PRODUCE STEAM USING THIS HEAT; PRODUCING HYDROGEN FROM THIS STEAM; PASSING AT LEAST A PORTION OF THE HYDROGEN FORMED TO THE HYDROTREATING ZONE; AND CATALYTICALLY HYDROTREATING THE GAS OIL PORTION IN THE HYDROTREATING ZONE. ALTERNATIVELY, THE HYDROGEN CAN BE PRODUCED BY REACTING THE CARBONACEOUS DEPOSITS ON THE CATALYTIC CRACKING CATALYST WITH STEAM.
