Selective adsorption and recovery of organic gases using ion-exchanged faujasite

摘要

This invention relates to a process for selectively adsorbing and recovering an organic gas containing unsaturated linkages from a mixture of gases over a cuprous ion-exchanged zeolite of the faujasite type. The process is particularly suited for adsorbing gases such as carbon monoxide and ethylene over a zeolite having a silica to alumina molar ratio from 1.5 to 3.0.
