ABSTRACT:
A sorbent capable of removing trace amounts of oxygen (ppt) from a gas stream at a high temperature above 200.degree. C. comprising a porous alumina silicate support such as zeolite containing from 1 to 10 percent by weight of ion exchanged transition metal such as copper or cobalt ions and 0.05 to 1.0 percent by weight of an activator selected from a platinum group metal such as platinum. The activation temperature, oxygen sorption and reducibility are all improved by the presence of the platinum activator.
