Abstract
Structured zeolite coated structures comprising thick porous inorganic zeolite coatings disposed on monolithic support structures, which can be honeycomb shaped, are disclosed. The zeolite coatings have open interconnected pores of controlled pore size and are characterized by improved durability, physical integrity, and adherence sufficient to enable use as supports for catalysts in liquid phase applications under harsh reaction conditions. Methods for making zeolite coated structures are also disclosed.
