使用200 mL固定床反应器,在专用催化剂作用下,考察了工艺条件对催化裂化(FCC)轻汽油原料催化裂解生产低碳烯烃反应性能的影响。结果表明:在专用催化剂作用下,FCC轻汽油原料经催化裂解可制得低碳烯烃中的乙烯、丙烯和丁烯,并且产物中的m(丙烯)/m(乙烯)大于1.40,远高于其经蒸汽热裂解增产丙烯工艺下的0.43;反应温度对C≥5液相产物组成中的芳烃收率增幅影响很大;较高的质量空速不利于低碳烯烃的生成;去离子水的存在及增多,不仅促进丙烯的生成,还有利于抑制催化剂结焦生炭。在反应温度为500 ℃、液时质量空速为1.0 h-1、反应压力为0.13 MPa、注水量[m(去离子水)/m(FCC轻汽油原料)]为40%的催化裂解优化工艺条件下,丙烯、乙烯、丁烯收率分别达4.44%,9.87%,8.27%,m(丙烯)/m(乙烯)达2.22。
- Abstract:
-
The effect of process conditions on catalytic cracking of FCC light gasoline to produce low carbon olefins was investigated in a 200 mL fixed- bed reactor with the special FCC catalyst. The results showed that low carbon olefins,such as ethylene,propylene and butene,could be obtained from FCC light gasoline by catalytic cracking,and m(propylene)/m(ethylene) in the products was more than 1.40,which was much higher than 0.43 that by the steam pyrolysis process. The yield of aromatics in the liquid phase C≥5 products was greatly influenced by the reaction temperature. High mass space velocity was not conducive to the production of low carbon olefins. The presence and increase of the deionized water not only promoted the yield of propylene,but also helped to inhibit the catalyst coking. Under the optimized catalytic cracking conditions of the reaction temperature at 500 ℃,the mass space velocity at 1.0 h-1,the reaction pressure at 0.13 MPa,and the water injection amount of m(deionized water)/m(FCC light gasoline) at 40%,then the yield of propylene,ethylene and butene were up to 4.44%,9.87%,8.27%,respectively, and m(propylene)/m(ethylene) reached 2.22.
