1. A structured adsorbent bed for purification of a gas feedstream comprising:
- a substrate having a cell density greater than 1040 cells per square inch (cpsi), wherein the substrate is a non-porous solid selected from a metal;
a metal oxide layer that has been formed on the surface of the substrate by heating the substrate to a temperature from about 900°
C. to about 1050°
C.;
a primer layer on the metal oxide layer, wherein the primer layer is a zirconium-containing layer; and
a coating on the zirconium-containing layer, wherein the coating comprises adsorbent particles and a binder.
