ABSTRACT:
The invention combines two unit operations i.e. fluid catalytic cracking (FCC) and circulating fluid bed (CFB) boiler technologies. The circulating solid inventory of the CFB boiler is introduced to the bottom of a conventional FCC unit to supply the endothermic heat of reaction. A once-through FCC catalyst is introduced under high-temperature, short residence time conditions whereby improved yields are achieved through the reduction of coke made in the FCC unit.
