• 二烯烃

  Catalyst promotes reactions of cracking,isomerization and aromatization. Products from catalyst cracking have more economic value than those from thermal cracking:more C3,C4 and more isomer in the gas,more isohydrocarbon,little dialkene and more aromatic hydrocarbon in gasoline.

  催化裂化是按碳正离子机理进行的,催化剂促进了裂化、异构化和芳构化反应,裂化产物比热裂化具有更高的经济价值,气体中C3和C4较多,异构物多;汽油中异构烃多,二烯烃极少,芳烃较多。
