Abstract
Procedure for the purification of exhaust gases emitted by an internal combustión engine of the diesel type characterized in that said gases are passed through a device constituted by a mesh of metallic wires coated with alumina deposited from an alkaline and subsequent aluminate solution calcination introduced in a metallic enclosure located in the exhaust circuit of said engine, said alumina exhibiting a specific surface area at least equal to 120 m2/gram, the temperature of the purification device being at least 250ºC and the duration of contact between said exhaust gases being the same. And said alumina of at least 03 seconds. (Machine-translation by Google Translate, not legally binding)
