PROCESS FOR RE-ACTIVATION OF SOLID ACID CATALYST |
摘要 |
A process is disclosed for re-activating a used solid acid catalyst wherein the catalyst is calcined to burn off heavy hydrocarbons and subsequently halogenated with chlorine and/or fluorine or their compounds entrained by an inert gas or a non-reducing gas. The resulting re-activated catalyst finds wide application in isomerization and oligomerization of olefins, conversion of methanol into hydrocarbons, and isomerization, disproportionation or trans-alkylation of aromatic hydrocarbons. |
