中国石化安庆石油化工总厂炼油厂４０万ｔ／ａ催化裂解装置是世界上目前已投产的最大的催化裂解工业装置。该装置已平稳运行两个周期，标定结果良好，表明我国自行研究开发的催化裂解成套技术在大型工业化装置上的应用获得了成功。装置操作弹性范围为６０％～１２８％。在设计负荷和５５０℃反应温度下，液化气产率达３８．３５％，丙烯产率达１７．３４％，均超过了设计值。在１２８％设计负荷下的液化气及丙烯产率分别为３９．４７％和１８．５０％。 Sinopec Anqing Petrochemical Plant Refinery 400,000 t / a catalytic cracking unit is the world’s largest catalytic cracking plant has been put into operation. The device has been running smoothly for two cycles and the calibration results are good. It shows that the complete set of catalytic cracking technology researched and developed by our country has been successfully applied to large-scale industrial installations. Device operating flexibility range of 60% to 128%. At design load and reaction temperature of 550 ℃, the yield of liquefied gas reached 38.35% and the yield of propylene reached 17.34%, all exceeding the design value. Liquefied petroleum gas and propylene yield at the design load of 128% were 39.47% and 18.50%, respectively.
