Title:
METHOD FOR SELECTIVELY ADSORPTING CO2 BY ZEOLITE
Document Type and Number:
Japanese Patent JPH01160816
Kind Code:
A
Abstract:
Carbon dioxide is selectively adsorbed and separated from non-acidic gases such as nitrogen, hydrogen and methane using a pressure swing adsorption process in a fixed adsorption bed containing a faujasite type of zeolitic aluminosilicate containing at least 20 equivalent percent of at least one cation species selected from the group consisting of zinc, rare earth, hydrogen and ammonium and containing not more than 80 equivalent percent of alkali metal or alkaline earth metal cations.
