ABSTRACT:
The converter includes a catalyst carrier in the form of a woven, porous sheet of a fibrous thermally-resistant material consisting predominantly of silica or alumina. The porous sheet is impregnated with a catalyst and thereafter calcined in a reducing atmosphere in order to activate it. The catalyst is a well-known material for facilitating the complete combustion of the exhaust gases. The porous net-like sheet is produced by using fibers of highly heat-resistant material consisting predominantly of silica, with extremely low alkali content, or by the use of fibers of a chemically and thermally stable quartz or special glass. The fibers used to produce the sheet may advantageously be twisted beforehand.
