A process for adsorbing hydrocarbons from an acid gas stream includes passing the acid gas stream through an adsorbent that selectively removes hydrocarbons, desorbing the hydrocarbons from the adsorbent and contacting the desorbed hydrocarbons with an acid gas removal solution to remove acid gases

A process for adsorbing hydrocarbons from an acid gas stream includes passing the acid gas stream through an adsorbent that selectively removes hydrocarbons, desorbing the hydrocarbons from the adsorbent and contacting the desorbed hydrocarbons with an acid gas removal solution to remove acid gases which have been coadsorbed with the hydrocarbons. The process is particularly useful in removing hydrocarbons from a hydrogen sulfide-containing stream that is being directed to Claus processing for conversion into elemental sulfur. Useful adsorbents include Y-type zeolites having a silica to alumina mole ratio of less than 15 and a reduced sodium content.
