减压渣油经渣油裂解和焦炭气化再生工艺得到利用。该工艺首先将减压渣油催化裂解为低碳烯烃和轻质油产品，然后将裂解生成的焦炭在双功能碱催化剂作用下气化为富氢合成气。在双流化床反应器上研究了它们对减压渣油裂解气化的影响。结果表明，与硅砂和水热处理沸石催化剂（FCC催化剂）相比，固体碱催化剂可提高轻质烯烃收率（具有较高的烯烃度），并抑制焦炭的生成。此外，在CaO/Al 2 O3摩尔比为12：7时制备的催化剂比在摩尔比为1：1时制备的催化剂表现出更好的裂化效果。讨论了反应温度和剂油比对减压渣油固体碱裂解液分布的影响。结果表明，重…
Vacuum residue is utilized by a process involving the residue cracking and coke gasification regeneration. In this process, vacuum residue is first converted into the products of light olefins and light oils by catalytic cracking, and then the cracking-generated coke is gasified into H2-rich syngas by using a bifunctional base catalyst. Their cracking gasification effects of vacuum residue are studied in a dual fluidized bed reactor. The results show that the solid base catalysts could enhance light olefin yield (have high olefinicity) and inhibit the formation of coke in comparison with silica sand and a hydrothermal treatment zeolite catalyst (FCC catalyst). Furthermore, the catalyst prepared at a CaO/Al2O3 molar ratio of 12:7 displayed a better cracking effect than the one produced at the molar ratio of 1:1. The effects of the reaction temperature and the catalyst-to-oil ratio on the distribution of cracking liquid from vacuum residue solid base cracking are discussed. The results showed that the heavy...
