Status and development of inorganic membranes and inorganic membrane reactors

Inorganic membranes are superior to organic ones in respect of thermal,chemical and mechanical stability and resistance to microbial degradation.So,they are widely used in the fields of the chemical engineering,the environmental protection and the biochemical engineering.Membrane reactors are the devices that combine a reaction process and a separation proccess in the same unit.Many researching results show that membrane reactors can increase efficiently the conversion rate and the selectivity of the convertible reaction and the yield of the products.The preparation of inorganic membranes,the types and the construction of inorganic membrane reactors were reviewed.There are some main subjects that should be deeply investigated in the future.
