Synthetische Filme mit Zeolithkristallkörpern, Verfahren für ihre Herstellung und ihre Anwendung.

摘要

A synthetic film constituted of zeolite crystal body and alumina substrate; the alumina substrate containing more than 90wt% of alumina with pores having a mean diameter of 0.1-3.0 mu m and the zeolite crystal body is formed in the pores and on the substrate. Such synthetic film is manufactured by preparing the alumina substrate; immersing the substrate in a slurry containing zeolite crystal and its precursor prepared from a silica source using sodium silicate or water glass; and subjecting the substrate with a slurry to a hydrothermal crystallization one time or more.
