ABSTRACT:
Semipermeable membranes prepared from at least one cellulosic polymer, such as cellulose triacetate, and containing at least one silicon compound, such as tetraethoxy silane, are useful for the separation of various gaseous mixtures into their constituent parts, such as separating natural gas into enriched fractions of carbon dioxide and methane.
