摘要： A catalytic conversion process can convert inferior feedstock to high quality fuel oil and propylene. A inferior feedstock is introduced into first and second reactor zone, wherein the feedstock carry out first step and second step reactions by contacting with catalytic conversion catalyst. Product vapors separate from spent catalyst by gas-solid separation. The spent catalyst is stripped, regenerated by burning off coke and then returns to reactor. The product vapors are introduced into separation system to obtain propylene, gasoline, diesel, fluid catalytic cracking gas oil (FGO) and other products. The FGO is introduced into hydrotreating unit and/or extraction unit to obtain hydrotreated FGO and/or extracted FGO. Said hyrotreated FGO and/or extracted FGO return to the first reactor zone and/or another catalytic cracking unit to obtain propylene and gasoline. The extracted oil of said FGO is rich in double ring aromatics which are good chemical materials. The raffinate of said FGO is rich in chain alkane and cycloalkane which are suitable for catalytic cracking. More particularly, the invention relates to a process to utilize petroleum oil resources efficiently for decreasing the yield of dry gas and coke significantly.

Catalytic cracking, hydrogenation, solvent extraction, hydrocracking and process for producing more diesel are organically combined together, and hydrocarbons such as alkanes, alkyl side chains in the feedstocks for catalysis are selectively cracked and isomerized. Meanwhile, aromatics in the feedstocks, which enter into the diesel fraction, are minimized, and the retention of other components in the diesel fraction by the production of aromatics via the reaction such as aromatization and the like is avoided. While the feedstocks are converted into high cetane number diesel and propylene, the yields of dry gas and coke are significantly reduced, and the breaking tendency and consumption of the catalyst are decreased.

The fluid catalytic cracking gas oil is fed into other unit for further treatment or is fed back to the initial catalytic conversion reactor. The process allows the maximum production of high cetane number diesel, the cracking catalyst having a coarse particle size distribution can further improve the selectivity of dry gas and coke, and can reduce the breaking tendency of the catalyst and the consumption of the catalyst.
摘要翻译：一种用于增加柴油的十六烷值桶的催化转化方法，其中催化转化反应器中原料油与主要含有大孔沸石的相对均相活性的催化裂化催化剂接触，其中反应温度，油的停留时间催化剂/原料油的蒸气和重量比足以获得含有约12至约60重量％的流化催化裂化瓦斯油相对于原料油的重量并含有柴油的反应产物; 反应温度范围为约420℃至约550℃; 油蒸气的停留时间为约0.1至约5秒; 催化裂化催化剂/原料油的重量比为约1-约10.流化催化裂化瓦斯油进料到其他单元进行进一步处理或反馈到初始催化转化反应器。该方法允许最大限度地生产高十六烷值柴油，具有粗粒度分布的裂化催化剂可以进一步提高干燥气体和焦炭的选择性，并且可以降低催化剂的破坏趋势和催化剂的消耗。
