摘　　要：在采用MIP技术的280万吨/年催化裂化装置,试验调整装置催化剂种类、原料性质和操作条件等多方面因素,寻找提高装置汽油辛烷值的有效途径,为今后的装置的优化生产提供指导。结果表明:装置最佳反应温度应选择在520~525℃;使用MIP专用剂能够有效的提高汽油辛烷值,但是辛烷值提高后,汽油收率下降较快;在烧焦及取热符合允许的情况下,适当提高掺渣量有利于装置汽油辛烷值的提高。In a 2.8 million ton/year catalytic cracking unit using MIP technology,attempting to adjust various factors such as catalyst type,raw material properties,and operating conditions of the unit,an effective way was found to increase the octane number of gasoline in the unit,providing guidance for future optimized production of the device.The results indicated that the optimal reaction temperature of the device should be selected between 520~525℃.The use of MIP special agent can effectively improve the octane number of gasoline,but after the octane number increased,the gasoline yield was falling rapidly.When the coking and heat extraction met the allowable conditions,properly increasing the amount of slag added was beneficial for improving the octane number of gasoline in the unit.
