Carbon molecular sieving membranes are new, high-performance materials for gas separations. The selectivities of these membranes are much higher than those typically found with polymeric materials, and the selectivities are achieved without sacrificing productivity. Ultramicroporous carbon membrane
## Abstract **Summary:** Carbon molecularβsieve membranes (CMSMs) have shown great potential for gas separation. They exhibit high selectivity by permitting effective sizeβ and shapeβseparation between gas molecules of similar molecular dimensions. Hence, the control of their pore size is very impo
