ABSTRACT:
A process for the removal of inert gases, such as nitrogen and carbon dioxide, from methane-containing gases, such as natural gas, including a first stage removal which lowers the total combined inert content to about less than 30% and a second stage removal utilizing a pressure swing adsorption process comprising one or more adsorbent beds comprising contracted titanosilicate-1 adsorbent, wherein the purified methane-containing gas contains less than about 6% total combined inerts.
