重质油在加工过程中的化学结构变化及其轻质化

Changes of Chemical Structures of Heavy Oils during Processing and Their Conversion

提出可把任一油品看成由若干“基团”组成的观点.讨论了在重质油轻质化过程(包括催化裂化、焦化、减粘裂化、加氢处理和加氢裂化)中各基因变化的规律,进而对各个加工过程及其在总加工流程中的作用进行了综合评价.

The viewpoint of that any fraction can be considered as being composed of a number of 'basic groups' was put forward. The changing principles of various basic groups in the conversion processes (including catalytic cracking, coking, visbreaking, hydrotreating and hydrocracking) of heavy oils were dis-cussed. furthermore, each process and its role in the refinery scheme were evaluated comprehensively.
