SYNTHESIS OF THIN ZEOLITE Y AND ZEOLITE ZSM-5 FILMS ON FECRALLOY METAL

摘要

This work is aimed of the growth of Zeolite coatings (e.g. ZSM-5 and zeolite Y) onto a metal surface for catalytic application. Usually, zeolites are used in powder composite form (pellets) and are backed to form a fixed bed. Disadvantages are the pressure drop, diffusion problems, and hot and cold spots[1-2]. However, the structured catalysts with large channel guarantee low pressure drop and improve mass and heat transfer [3-4]. In addition, small zeolite crystals which are adhere on the metal surface and form thin layer, improved effectiveness, and faster diffusion. [5].
