摘　　要：介绍了北京燕山石油化工公司Ⅱ套催化裂化装置在提高渣油掺炼率的改造中所采取的防止反应系统和分馏系统结焦的技术措施 ,并提出了进一步减少结焦的建议。装置一年多的运转结果表明 ,改造后装置的结焦比改造前大为减少。A summary is give on technical measures adopted to prevent coking in the reaction system and fractionation system of FCC unit for the revamping project of the second FCC unit in Yanshan Petrochemical Company, whose objective is to increase residue blending ratio. After revamping, coking in the unit has been greatly reduced. Suggestions for further decreasing coking in the unit have been proposed.
