SEPARATION MEMBRANE-POROUS MATERIAL COMPOSITE AND METHOD FORMANUFACTURING THE SAME

摘要

A separation membrane-porous material composite (1) being improved in flu x and selectivity, which comprises a porous ceramic material and a separatio n membrane formed on the porous material, wherein a composite layer (65) hav ing a thickness of 1 mm or less is provided at the interface between the por ous material (61) as a dense layer (64) and the separation membrane (66) bei ng formed as a carbonaceous film while maintaining an increased pressure ins ide the porous material to avoid penetration of the carbon layer precursor i nto the pores.
