Know as a refining method of a natural gas is a method using a separation membrane.Application of
organic mambranes is limited by their low thermal and chemical stablility. Recenthly the molecular-sieve
inorganic membrane has been studied extensively.DDR type zeolites are regarded as good candidates to be
utilized for this purpose.This membrane has an industrially acceptable thi ckness and is formed on a
substrate.This membrane separates at least one type of a gas mixture including identified gases
specially 2 CO and 4 CH .For increasing mechanical strength of this membrane, a method for preparing DDR
membrane composite,is described.
