摘　　要：在对催化裂化反应机理分析的基础上,提出了一种新的催化剂并联流动的双提升管催化裂化反应体系———灵活多效催化裂化(FDFCC)工艺。该工艺能显著降低催化裂化汽油的烯烃含量,中试及工业应用结果表明,烯烃含量可降低20%～30%,硫含量下降15%左右,改质汽油诱导期增加,马达法辛烷值(MON)和研究法辛烷值(RON)略有增加,苯含量基本维持不变,芳烃含量远小于规定指标。Based on the analysis of the flexible dual-riser fluid catalytic cracking (FCC) reaction mechanism, a novel reaction process with dual-riser reactors, in which catalysts flow in parallel (FDFCC process), is proposed, which can effectively decrease the olefin content in catalytic gasoline. The results of pilot-plant tests and industrial applications show that the olefin content in catalytic gasoline drops by 20-30 percentage points, sulfur content is reduced by about 15%, motor octane number (MON) and research octane number (RON) increase slightly while maintaining its benzene content nearly unchanged and its aromatics content being below the specification greatly.
