PROCESS FOR SEPARATING GASES AND ADSORBENT COMPOSITIONS USED THEREIN |
摘要 |
The present invention relates generally to a composite adsorbent comprising at least a zeolite-containing CO2 removal adsorbent and 10% or more of a metal oxide having a heat capacity of at least 20 cal/mol-° K (83.7 J/(mol·K). The composite is preferably used in a multi-layered adsorption system in a cyclic adsorption process. The adsorption system comprises two or more layers wherein the first layer is at least a water vapor removal adsorbent, such as activated alumina, and the second layer is the novel composite adsorbent. The adsorption system is preferably used in a PSA prepurification process prior to cryogenic air separation. |
