Title: Catalysts for selective catalytic reduction denox technology
Inventor: HEGEDUS LOUIS
IPC: B01J35/10
Filed: 1989-05-15
Granted: 1994-10-18
Abstract: Abstract of the Disclosure Catalysts for the selective catalytic reduction of NOx by ammonia are made from porous formed supports having a certain fraction of the pores with pore diameters larger than 600 Angstrom units.  Thus macropores can be introduced in a formed TiO2 support by adding burnout materials or some inorganic oxide prior to forming the titania into the formed support. Alternatively, titania is precipitated onto a porous inorganic oxide such as SiO2, Al2O3, ZrO2, AlPO4, Fe2O3 and B2O3 to form the support.  Then conventional DeNOx catalytic metals are added.  The support can be made by first impregnating the inorganic oxide particles with titania via a soluble precursor, forming titania and then shaping the coated particles into the desired shape such as a monolith.  In a second embodiment, the inorganic oxide particles are first formed into the desired shape and then impregnated with the titania forming material.  Barium sulfate can be added to the surface of the porous inorganic oxide to make an improved support.
