Abstract

A catalytic vessel for adsorbing catalytic metals, such as from automotive exhaust gases, and carrying out three-way catalysis includes an inlet at an upstream end, a plurality of catalytic chambers located downstream of the inlet, and an outlet. At least one of the catalytic chambers contains a plurality of sheet members preferably made of steel and adapted for deposition of a metal selected from the group of noble and non-noble metals, and more particularly from the group consisting of platinum, rhodium, rhenium, palladium, and gold. The vessel may be used in a catalytic system which contains a liquid source of metal catalysts, such as a solution or a gasoline additive, means for adding metal catalysts to a combustion system, and the catalytic vessel, which collects the metal catalysts and is a site for three-way catalytic conversion of starting materials such as automotive emissions to final products.
