对以“低温接触、大剂油比”理念为基础的催化裂化技术的可实施方式进行系统分析,论述实施这一技术的两种形式:即系统与环境间存在物质或能量交换,以及系统与环境间无物质或能量交换。讨论实施这一理念的各种具体工艺技术,这些技术在改善产品分布、生产清洁燃料及实现生产过程清洁化以及增强重油裂化能力方面发挥了重要作用。 A systematic analysis of the ways in which catalytic cracking technology based on the concept of “low temperature contact, high fuel ratio” can be implemented, discusses two forms of implementing this technology: the exchange of matter or energy between the system and the environment, and No material or energy exchange between system and environment. Discuss various specific process technologies that implement this concept that play an important role in improving product distribution, producing clean fuels, and cleaning up production processes, as well as enhancing heavy oil cracking capacity.
