Abstract

A process and catalyst is disclosed for the reduction of the ignition temperature of diesel soot filtered out of the exhaust fumes of diesel engines by passing the exhaust stream through a filter element. The filter element is a temperature resistant inert support onto which is deposited a catalytically effective amount of silver vanadate or a mixture of the temperature resistant carrier material and a catalytically effective amount of silver vanadate.
