FCC family technologies, such as DCC, MGG and CPP, take the advantages of boththermal and catalytic reactions. A zeolite containing material is acted as heat carrier and catalyst aswell. Versatile objectives can be achieved through regulating the catalyst formulation and optimizingthe process variables. The ethylene, propylene and isobutylene from these FCC family technologiescan be yielded 24.3wt%, 22.9wt% and 6.1wt% respectively with heavy feeds. The cracked naphtha isrich in toluene and xylenes.
