This invention is a graded catalyst comprising palladium and also a partial combustion process in which the fuel is partially combusted using that catalyst. The catalyst utilizes a catalytic support structure suitable for high flow rates of combustible gas mixtures through it. The catalyst is situated on the support so that in the flowing gas stream a leading portion of the support has a higher combustion activity, such as by a higher concentration of catalytic metal, than has the trailing portion. The combination of graded catalyst and support provides ...
A catalyst structure comprised of: a. a catalyst support having longitudinal passageways adapted for the passage of combustible gas and having surfaces in those passageways for the placement of a catalyst material and having an inlet zone and an outlet zone spaced apart along the axis of the passageways, b. a catalyst material comprising palladium on at least a portion of the support longitudinal passageways and having a relatively higher activity in the inlet zone than in the outlet zone.
