| 摘要 |
An object of the invention is to provide a process for industrially and easily producing, in a short time period, a porous support-zeolite membrane composite which is excellent in terms of acid resistance and water resistance, has a sufficient permeation flux, and is suitable not only for the separation of lower alcohols but also for separating substances which react with acid sites of zeolites, such as electrophilic molecules. The present invention relates to a process for producing a porous support-zeolite membrane composite, which comprises forming a CHA type zeolite membrane on a porous support by a hydrothermal synthesis in the presence of seed crystals, wherein an FAU type zeolite is used as the seed crystals. |
