催化裂化柴油催化转化生产高附加值产物的研究进展

摘要/Abstract

摘要： 寻求符合催化裂化柴油（LCO）资源禀赋的高附加值转化技术是化解柴油产能过剩、拓宽轻质芳烃等高附加值产物来源的重要途径。重点介绍了基于不同技术路线的LCO转化工艺，详细阐述了原料性质、分子筛类型和操作条件等因素对加氢LCO催化转化生产高附加值产物性能的影响。同时指出：LCO转化技术在多产轻质芳烃方面还存在较大提升空间，对LCO进行加氢处理-催化裂化的加工路线可充分发挥催化裂化反应体系的诸多优势；目前，对加氢LCO催化裂化转化规律的认识仍局限于全馏分的LCO，要加深对加氢LCO窄馏分、组分油以及关键模型化合物催化裂化反应规律的认识。

Abstract: It is an important way to seek high value-added conversion technology in accordance with the resource endowment of FCC diesel (LCO) to solve the problem of over-capacity of diesel and to widen the source of light aromatics. The LCO conversion process based on different technical routes was introduced，and the effects of raw material properties，molecular sieve types and operating conditions on the performance of hydrogenated LCO catalytic conversion to produce high value-addedd products were described in detail. At the same time，it was pointed out that LCO conversion technology had great petential for improvement in producing light aromatics，and LCO hydrotreating-catalytic cracking process could give full play to the advantages of catalytic cracking reaction system. At present，the understanding of the conversion law of hydrogenated LCO is still limited to the full fraction，so it is necessary to deepen the understanding of the law of hydrogenated LCO's narrow fraction，components and the catalytic cracking reaction of key model compounds.

Key words: FCC lighe cycle oil, hydrocracking, hydrotreating, gasoline, aromatics
