PROCESS FOR LOWERING THE IGNITION TEMPERATURE OF DIESEL-OIL SOOT FILTERED FROM EXHAUST GASES OF DIESEL ENGINES

摘要

A catalyst process is disclosed for the reduction of the ignition temperature of Diesel soot filtered out of the exhaust gas of Diesel engines by passing the exhaust gas over a catalytically active substance, which is selected from lithium oxide, copper chloride, vanadium oxide/alkali metal oxide combinations, a vanadate of an alkali metal or of cerium, or a silver or alkali metal perrhenate, preferably of sodium or silver, or mixtures of these substances.
