Abstract

See full text

An air prepurification process which includes, as a first step, a pressure swing adsorption process in which the air is passed through a bed of adsorbent which contains activated alumina, thereby effecting removal of substantially all moisture and most carbon dioxide from the feed air and as a second step, a temperature swing adsorption process in which the dried feed air is passed through a bed of carbon dioxide-selective adsorbent, thereby removing substantially all of the carbon dioxide remaining in the feed air. The feed air may be passed through beds of hydrogen oxidation and carbon monoxide oxidation catalysts between the first and second steps to convert any hydrogen and carbon monoxide in the feed air to water vapor and carbon dioxide, respectively, these components being removed from the feed air during the second step. The feed air may be optionally passed through a layer of a hydrocarbon selective adsorbent between the first and second steps to remove hydrocarbons such as ethylene, propylene and propane.
