ABSTRACT:
The invention relates to a process for removing hydrogen halides from hydrocarbon containing streams. More particularly, the invention relates to a process and an HCl sorbent for the removal of HCl and other hydrogen halides from hydrocarbon streams to prevent the formation of green acids. The sorbent has a high capacity for sorption of HCl, sufficient physical strength to permit operation in packed bed form, and catalytic inertness to not causing the oligomerization reactive hydrocarbons such as olefins, diolefins. The HCl sorbent comprises an admixture of magnesium hydroxide and a hydrogen halide reactive component such as calcium hydroxide or oxide with at least one or more metal oxide, hydroxide or carbonate wherein the magnesium is present in an amount greater than about 5 mol-% of the total cation content of the sorbent.
