ABSTRACT:
A method for impregnating porous monolith supports with catalytically active materials is disclosed. The impregnation is carried out at a temperature which substantially reduces chemisorption rates such that reactions between the monolith substrate and catalytically active materials in the catalyst solution are minimized. The process can be completed in a practical time that allows for unit selectivity of the weight ratio of catalytically active materials in the substrate to the weight ratio of catalytically active materials in the catalyst solution.
