A separation membrane-porous material composite (1) being improved in flux and selectivity, which comprises a porous ceramic material and a separation membrane formed on the porous material, wherein a composite layer (65) having a thickness of 1 mm or less is provided at the interface between the porous material (61) as a dense layer (64) and the separation membrane (66) being formed as a carbonaceous film while maintaining an increased pressure inside the porous material to avoid penetration of the carbon layer precursor into the pores.
La présente invention concerne un composite membrane de séparation / matériau poreux (1) présentant des qualités accrues de flux et de sélectivité. Il est constitué d'un matériau poreux et d'une membrane de séparation formée sur le matériau poreux. Une couche composite (65) d'une épaisseur n'excédant pas 1 mm est disposée à l'interface entre le matériau poreux (61) constituant une couche dense (64) et la membrane de séparation (66) formée d'un film carboné.
