Abstract
A catalyst structure is formed by forging catalytic particles from a slurry into the surface of a metal substrate such that the particles protrude from the surface and are permanently fixed into the surface. The forging is accomplished by engaging rollers with the surface as it passes through the slurry to press the particles into the surface. The rollers may be brush rollers, fabric rollers or solid rollers. The particles may be any particles which have catalytic activity for a particular purpose and which are hard enough to forge into the metal substrate.
Claims7
A method of forming a catalytic structure comprising oxide catalyst particles dispersed over and forged into a surface of a substrate comprising the steps of:
- (a) providing a substrate web;
- (b) forming a slurry of oxide catalyst particles of a composition capable of being forged into a surface of said substrate web;
- (c) applying said slurry to said surface of said substrate web;
- and
- (d) rotating a graining brush in engagement with said surface of said substrate web having said slurry thereon with a force sufficient to forge said oxide catalyst particles partially into said surface and permanently fix said oxide catalyst particles to said substrate web and leave said oxide catalyst particles protruding from said substrate web.
