摘要
Processes are disclosed for the separation of light hydrocarbons from a feedstream containing hydrogen, light hydrocarbons and heavy hydrocarbons. The processes employ thermal swing adsorption zone to adsorb heavy hydrocarbons and a pressure swing adsorption zone to remove the remaining light hydrocarbons. At least a portion of the product from the pressure swing adsorption zone is used to purge the thermal swing adsorption zone. Specific applications of the process of the present invention are disclosed with relation to hydrodealkylation processes and dehydrocyclodimerization processes.
