Abstract
A sorbent composition comprising a first sorbent bed of hygroscopic aluminosilicate sorbent and a second sorbent bed comprising an aluminosilicate sorbent impregnated with an aqueous base solution, whereby the hygroscopic aluminosilicate sorbent provides an initial contact zone to protect upstream gas and processing equipment from reaction products resulting from back-diffusion of water which will occur in the absence of the first sorbent.
