Method for preparing support of molecular sieve membrane
A method for preparing a support of a molecular sieve membrane is provided and relates to a technical field of support preparation, including steps of: according to a molar ratio of magnesium, aluminum and silicon in cordierite, preparing a nanometer composite sol of magnesium, aluminum, silicon and lanthanum serving as a sintering aid through a sol-gel method, enveloping and bonding the sol on a surface of dispersed nano-sized cordierite powders, and transforming the sol into nanometer composite oxides through presintering; mixing the cordierite powders, a binder and water, forming mud, extruding the mud, forming the mud into a green body, and sintering the green body into a cordierite support; coating a layer of film on the cordierite support with an aqueous dispersant of zirconia, then sintering, and obtaining a support of a molecular sieve membrane, composited by a cordierite main support layer and a zirconia film layer.
