Direct processing of Bach Ho crude oil by high temperature catalytic cracking at laboratory scale
Abstract
The direct crackings of Bach Ho crude oil and atmosphere residue over equilibrium FCC catalyst (Ecat) and Ecat combined with ZSM-5 were carried out at 520 - 650oC to increase light olefin yield (C2 - C4 olefins). When increasing the temperature from 520 - 620oC, the yield of light olefin increased by 8 - 9%wt for both Bach Ho crude oil and atmosphere residue. At 650oC, up to 24 - 26% light olefins can be obtained. The addition of ZSM-5 enhances the conversion of gasoline to light olefins, increasing the total yields of C2 - C4 olefins to 30% with 16% propylene. However, raising the temperature too high or adding ZSM-5 too much will produce a large amount of undesirable product, dry gas.
