催化裂化最新技术进展

【摘要】催化裂化是石油炼制过程之一，是在热和催化剂的作用下使重质油发生裂化反应，转变为裂化气、汽油和柴油等的过程。我国的石油炼化行业伴随经济的发展也获得了大力的发展，因此催化裂化技术就变得更加的重要了。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.

【Abstract】Catalytic cracking is one of the processes of petroleum refining, is in thermal and catalyst under the action of the heavy oil cracking reactions take place, into the process of cracking gas, gasoline and diesel fuel. China's oil refinery and petrochemical industry with economic development also has been vigorously developed, so catalytic cracking technology becomes more

important. Our first set of FCC unit in 1965 since industrialization, has developed a zeolite catalyst riser catalytic cracking, catalytic cracking, catalytic cracking residue, reducing series riser catalytic cracking and developing high selective catalytic cracking; experienced catalytic cracking unit, the technical level is from low to high, the device scale and processing capacity from small to large, tracking research ideas from imitation to innovation, has made great achievements, has reached the international advanced level. So far, the total processing capacity of the FCC has reached nearly 150 Mt/a, which accounted for the total residue catalytic cracking feed about 40%, gasoline and diesel group produced points respectively the gasoline and diesel product total 70% and about 30%, the amount of propylene production accounted for about 40%. of the total production of propylene and the catalytic cracking Device can also provide raw material for the alkylation unit and etherification unit. These achievements of China's oil refining industry processing heavy feedstock, improving the light oil yield and improve the quality of products and improve economic benefit plays a pivotal role.
