Abstract

A zeolite membrane composite includes a porous support and a zeolite membrane formed on the support. The zeolite membrane includes a low-density layer that covers the support, and a compact layer that covers the low-density layer. The compact layer has a higher content of a zeolite crystalline phase than the low-density layer. By in this way forming the compact layer on the low-density layer that covers the support, the thin compact layer with no defects can be formed more easily than in the case where a compact layer is formed directly on a support.
