摘　　要：为拓宽石油化工行业生产烯烃的原料来源,高值化利用劣质重油原料,在中型试验装置上进行重油高效催化裂解技术(RTC)工艺试验。试验结果表明:与催化裂解工艺(DCC)相比,RTC工艺在加工加氢蜡油与加氢渣油的混合原料(两者质量比为45∶55)时,液化气产率和丙烯产率均明显提高,干气产率和焦炭产率显著下降;在加工更为劣质的加氢渣油原料时,RTC工艺对改善产品分布和产品选择性均有良好效果。In order to broaden the resource of olefin production in petrochemical industry,and to utilize the heavy oil for high value,a serious of experiments for residuum to chemicals(RTC)technology was carried out on a pilot plant.The results showed that as compared with deep catalytic cracking(DCC)technology,the yields of LPG and propylene in RTC process were enhanced remarkably,and the yield of dry gas and coke were reduced when processing hydrotreating residuum blended feedstock.The RTC technology had good effect on the product distribution and product selectivity when processing heavier hydrotreated residuum.
