A process for treating a gas stream, such as natural gas, comprising a process design that prevents the formation of undesired sulfur and sulfates from the reaction of oxygen and sulfur is disclosed. After water is removed from the gas stream, a portion of the dried gas stream is sent through a cooled adsorbent bed that has a first layer to remove sulfur compounds and then a layer to remove oxygen. There may be additional layers of adsorbent to remove other contaminants. The gas stream that is then heated to regenerate an adsorbent bed no longer contains sulfur and oxygen and undesirable reactions of sulfur and oxygen are avoided.
