摘要
自我国第一套流化催化裂化装置于1965年实现工业化以来,先后开发出沸石催化剂-提升管催化裂化、渣油催化裂化、催化裂解、变径串联提升管催化裂化和正在开发的高选择性催化裂化;经历了催化裂化装置从无到有,技术水平由低到高,装置规模和加工能力从小到大,研究思路从跟踪模仿到自主创新,取得了巨大的成就,已跻身国际先进水平.到目前为止,全国催化裂化装置总加工能力已达到近150 Mt/a,其中渣油占催化裂化总进料约40%,所生产的汽油和柴油组分分别占全国汽油和柴油成品总量的70%和30%左右,所生产的丙烯量约占全国丙烯总产量的40%.同时,此催化裂化装置还可为烷基化装置和醚化装置提供原料.这些成果对我国炼油行业加工重质原料、提高轻质油收率和改善产品质量,进而提高经济效益起着举足轻重的作用.
Since the first Chinese fluid catalytic cracking (FCC) unit was commercialized in 1965, these milestone innovations and developments have been achieved in the historical sequence events of zeolite catalyst-riser FCC process, residue FCC process, DCC (deep catalytic cracking) process, multi-cascade riser FCC process and the ongoing high-selective FCC process in China. In the course of the development of Chinese FCC technology, many breakthroughs have been made, such as the quantifies of FCCU increased dramatically from the blank beginning, the technical level of FCCU enhanced higher and higher, the capacity of FCCU grew larger and larger, and the R&D on FCC technology was from the tracking mode to the independent innovation mode. Up to now, the total capacity of FCCU in China has been reached 150 Mt/a, in which the residue ratio of FCCU feedstock is around 40%. The outputs of FCCU are roughly taking up the components of 70%, 30% and 40% to gasoline pool, diesel pool and propylene pool respectively, as well as raw materials of alkylation units and etherificationunits. Now FCC is playing a decisive role in the aspects of heavy oil processing, higher light oil recovery, products qualification improving, and better economic benefits in the oil industry of China.
