Title:
ZEOLITE MEMBRANE COMPOSITE AND MEMBRANE REACTOR
Document Type and Number:
WIPO Patent Application WO/2023/085372
Kind Code:
A1
Abstract:
This zeolite membrane composite (1) comprises: a porous support body (11); and a zeolite membrane (12) which is provided on the support body (11) and contains aluminum, silicon and carbon. The molar ratio of carbon relative to the sum of aluminum and silicon in the zeolite membrane (12) is 0.1 or more. The zeolite membrane (12) can improve hydrothermal durability. In addition, in a case where a mixed liquid at 60°C containing 50 mass% of water and 50 mass% of ethanol is supplied to the zeolite membrane composite (1) at -94.66 kPaG on the permeate side, the total permeation flux is 1.0 kg/m2h or more and the water/ethanol separation coefficient is 1000 or more. The zeolite membrane composite (1) can achieve high water separation performance.
