工业催化裂化装置从技术发展的角度来说,最基本的是反应—再生形式和催化剂性能两个方面的发展。催化裂化装置一般由三个部分组成,即:反应—再生系统,分馏系统,吸收稳定系统。先后经历了固定床催化裂化、移动床催化裂化和流化床催化裂化。60年代出现了分子筛催化剂,由于它具有活性高、选择性和稳定好,占据主导地位的流化床反应器又发展为提升管反应器。同时还促进了再生技术的发展。陆续出现了两段再生、高效再生和完全再生等新技术。本设计结合当今世界的新工艺,新设备。在反应器、再生器、旋风分离器和提升管等设备方面都有很详细的大量计算。在工艺技术方面到达了装置技术先进,经济合理。
Industrial catalytic cracking unit from the technical point of view of development, the most basic reaction-regeneration form and catalyst performance in two aspects of development. Catalytic cracking unit generally consists of three parts, namely: reaction - regeneration system, fractionation system, absorption stability system. Has experienced fixed-bed catalytic cracking, moving bed catalytic cracking and fluidized bed catalytic cracking. The molecular sieve catalyst appeared in the 1960s. Due to its high activity, selectivity and stability, the dominant fluidized bed reactor was developed as a riser reactor. At the same time also promote the development of renewable technology. There have been two stages of regeneration, efficient regeneration and complete regeneration of new technologies. The design combines the new technology and equipment in today’s world. In the reactor, regenerator, cyclones and risers and other equipment have a very detailed and extensive calculation. In the process of technology has reached a device advanced technology, economic and reasonable.
