摘　　要：在中型试验装置上进行增强型催化裂解技术(DCC-PLUS)工艺试验。试验结果表明,DCC-PLUS工艺与DCC工艺相比,液化气产率、丙烯产率和丁烯产率均明显提高,干气产率和焦炭产率大幅度下降,汽油诱导期可达到529min。在加工掺混渣油原料时,DCC-PLUS工艺对改善产品分布和产品选择性的效果更加明显。A series of experiments for DCC-PLUS technology was carried out on pilot plant unit. Results showed that as compared with DCC technology, the yields of LPG, propylene and butylenes in DCC-PLUS process were enhanced significantly, at the same time, the yields of dry gas and coke were reduced; the induction period of gasoline reached 529 min. The improvement in product slates and product selectivity was even more significant when processing residue blended feedstock with DCC-PLUS technology.
