【摘要】：近10年来,中国石化石油化工科学研究院(RIPP)在开发新一代催化裂化技术,包括生产清洁燃料、加工劣质原料、生产化工原料等的催化裂化技术过程中,在反应化学基础理论方面获得了诸多新认识,如重油催化裂解链的引发反应路径具有多元性,大分子烃经五配位正碳离子引发链反应将导致大量干气的生成;正碳离子的异构化反应是影响丙烯生成的重要反应路径;丙烯是重油一次裂解反应和汽油中烯烃二次裂解反应的共同作用结果;乙烯的生成来自自由基反应和正碳离子反应等。概述了在新认识指导下形成的原始性创新技术及其工业实践结果,并展望了催化裂化技术的发展方向。
[Abstract]:In the past 10 years, RIPP has been developing a new generation of FCC technologies, including the production of clean fuels, the processing of inferior feedstocks and the production of chemical feedstocks. In the basic theory of reaction chemistry, many new ideas have been obtained. For example, the initiation path of catalytic cracking chain of heavy oil is diverse, and the reaction of macromolecular hydrocarbon through five-coordinated positive carbon ion initiation chain will lead to the formation of a large amount of dry gas. The isomerization of cationic ions is an important reaction path affecting the formation of propylene, and propylene is the result of both the primary cracking of heavy oil and the secondary cracking of olefin in gasoline. The production of ethylene comes from free radical reaction and positive carbon ion reaction. The original innovative technology formed under the guidance of new knowledge and its industrial practice results are summarized, and the development trend of catalytic cracking technology is prospected.
