Removal of CO2 from gases using activated alumina |
摘要 |
<p>The use of the activated adsorbent enables the simultaneous removal of carbon dioxide and water as a preliminary treatment of a gas mixture before a subsequent cryogenic separation. The purification of a gas containing carbon dioxide (CO2) as an impurity comprises adsorbing the CO2 on an adsorbent comprising particles of activated alumina. The alumina has a surface area of 200-299 m<2>/g and contains at least 80% alumina, silica (SiO2), iron oxide (Fe2O3) and 0.001-7.25% of an alkali or alkaline earth oxide. An Independent claim is also included for the use of the process in the purification of air or synthesis gas.</p> |
