摘　　要：在对目前国内外先进的催化裂化技术分析的基础上,结合 FDFCC 工艺特点,提出了实现"低温接触、大剂油比"的创新思想,开发了增产丙烯和生产清洁汽油的 FDFCC-Ⅲ工艺。中试结果表明.FDFCC-Ⅲ工艺能大幅度减少热裂化反应,增强催化裂化反应,促进原料硫向裂化气中转移。在中国石化长岭分公司1号催化裂化装置上进行工业应用的结果表明,重油提升管底部催化剂温度为630℃,剂油比为9.82;液化气及丙烯产率分别为26.66%和10.23%,干气产率仅为4.33%,汽油中烯烃体积分数为17.7%,汽油硫含量为0.032%。因此,该工艺技术能显著改善产品结构和产品性质,实现清洁汽油生产,具有良好的社会效益和经济效益。Based on the analysis of advanced FCC technologies,an innovation idea of operating the FCC unit under low contact temperature and high catalyst/oil ratio emerged, finatly, FDFCC-Ⅲ process for enhancing propylene yield and producing clean gasoline was developed. The test results of pilot plant showed that thermal cracking reactions were significantly suppressed and catalytic reactions were enhanced in FDFCC-Ⅲ process, thus promoting the transformation of sulfur from feed to cracked gas. The commercial application results of the FCC unit of SINOPEC Changling Company indicated that product slates and product qualities were improved by FDFCC-Ⅲ process significantly. When the heavy oil riser was operated at a catalyst/oil ratio of 9.82 and a riser bottom catalyst temperature of 630 ℃, the yields of LPG and propylene were 26. 66% and 10. 23%, respectively; the dry gas yield was only 4.33%;as to gasoline the volume content of olefins and sulfur content were 17. 7% and 0. 032%, respectively.
