Abstract
A composite sorbent is formed which is the reaction product of a solid alkali metal carbonate, rehydratable alumina and water or an aqueous solution of a metal salt. The reaction between the components occurs while forming particulates followed by curing and activation at high temperatures. The alkali metal in the sorbent exhibits a highly reactive and accessible state that is very favorable for various sorption applications. The sorbent is especially useful for removal of HCl and other acid contaminants from gas and liquid hydrocarbon streams at high temperatures.
