From: Control of zeolite framework flexibility for ultra-selective carbon dioxide separation
a Investigation on TMCT (one-minute overheating) temperature and CO2/CH4 separation performance comparison with the membranes detemplated by conventional calcination at 550 °C (CC550) and 700 °C (CC700). b Effect of TMCT period on CO2/CH4 separation performance. c Comparison on CO2/CH4 separation performance, involving commercial cellulose acetate (CA) membranes31, polyimide membranes29, Matrimid membranes30, carbon molecular sieve (CMS) membranes35,36,37, MOF membranes38,39,40, and other 8MR zeolite membranes28,32,33,34,52. d Gas permeation flux (F) and CO2/CH4 selectivity of 20 cm hollow fiber DD3R zeolite membrane in pure components (open symbols) and equimolar mixture (solid symbols) with pressure range of 3 to 31 bar (condition: room temperature, without sweep gas).
