摘　　要：综述了我国渣油催化裂化在工艺、设备、催化剂和自动控制等方面的发展水平,认为我国已初步形成具有自己特色的重油催化裂化技术,并已具备设计大型渣油催化裂化装置的能力。指出今后重油催化裂化技术开发的重点是简化流程、延长运转周期和提高装置适应市场需求生产多种产品的能力。提出了在降低焦炭产率的基础上提高氢有效利用率(E_H)和碳有效转化率(E_C)的观点,E_H和E_C数值反映了催化裂化过程中化学转化的有效程度,可以指导设计与生产。The state-of-the-arts of domestic residue catalytic cracking technology, including processes, equipments, catalysts and automatic control etc., were reviewed. It was considered that China has basically developed the residue catalytic cracking techniques with her own features, and is capable of designing large-scale residue catalytic cracking units. It has been pointed out that, in developing heavy residue catalytic cracking techniques in future, attentions should be concentrated to the simplification of process scheme, the extension of operating cycle as well as the enhancement of adaptability to the market requirements for multiple products. The viewpoint of increasing effective utilization of hydrogen( EH) and efficient conversion of carbon (Ec) based on the reduction of coke yield was proposed. The values of EH and EC represent the effectiveness of chemical conversion in the catalytic cracking process and can be used for guiding the unit design and production.
