DCC技术平台产业链的开发及其工业实践

对催化裂解（DCC）生成乙烯、丙烯和轻芳烃的反应化学进行研究，开发出高丙烯选择性的DCC-plus技术和兼顾乙烯和丙烯生产的CPP技术，形成了DCC技术平台以适应不同用户的产品需求。开发了DCC原料深度加氢处理技术，其脱硫率达95%以上，脱氮率达65%以上，降残炭率达76%以上，脱金属率达98%左右。而针对DCC产品特点开发的干气液相法制乙苯、丙烯直接氧化法制环氧丙烷、裂解石脑油抽提蒸馏制BTX（苯、甲苯、二甲苯）以及裂解轻油加氢裂化制BTX等特色化工利用技术，延伸了DCC技术平台的产业链，并在化工型炼油项目中成功地获得工业应用，开创了一条符合中国国情的非蒸汽裂解的炼化一体化技术路线。

DEVELOPMENT OF INDUSTRIAL CHAIN OF DCC TECHNOLOGY PLATFORM AND ITS COMMERCIAL PRACTICE

Based on the study of the reaction chemistry of DCC to produce ethylene, propylene and light aromatics, DCC plus technology with high propylene selectivity and CPP technology with ethylene and propylene production were developed, forming a DCC technology platform to meet the product needs of different users. The deep hydrotreating technology of DCC feedstock was developed. Its desulfurization rate is over 95%, denitrogenization rate is over 65%, carbon residue removal rate is over 76%, and metal removal rate is about 98%. According to the characteristics of DCC products, the characteristic chemical utilization technologies, such as dry gas liquid method for ethylbenzene, direct oxidation of propylene to epoxide, extraction distillation of DCC naphtha for BTX and hydrocracking of DCC light oil for BTX, have extended the industrial chain of DCC technology platform. All these have been successfully applied in chemical refining projects, creating a refining and petrochemical integration technology route in line with China's national conditions.
