Abstract: Catalytic elements are usable in waste gas control processes. The catalytic elements include an open inlet into a hollow body and a closed end thereby forcing fluid or gas through a porous catalytic layer of the element. The catalytic layer includes inorganic fibers and a catalyst disposed on or incorporated into the fibers. The catalytic element also includes an inductive heater disposed therein and a conductive layer about the inductive heater to transfer heat to the catalyst and fluid or gas.

Abstract: Methods of providing a homogeneous or uniform catalytic coating on an inorganic fiber substrate include using a vacuum to coat the substrate, improved coating solutions or mixtures and/or drying methods to prevent migration of metal catalyst precursors to the exterior surfaces and edges of the inorganic fiber substrate. The methods may include adding a component to the first coating solution or mixture before coating the inorganic fiber substrate; applying a second coating solution or mixture to the coated inorganic fiber substrate; drying the coated inorganic fiber substrate at ambient conditions, under controlled conditions, or with microwave radiation; or optimizing an amount of a salt, water, or an organic solvent in the coating solution.
