ENHANCED CATALYZED DIESEL SOOT FILTER, PROCESS FOR REDUCING IGNITION TEMPERATURE OR DIESEL SOOT OXIDATION TEMPERATURE FILTERED FROM DIESEL ENGINE EXHAUST GAS AND CATALYST. A catalyzed diesel soot filter and process. The diesel soot filter incorporates a porous filter element coated with a catalytic agent such that diesel soot from the diesel exhaust gas is deposited in contact with the catalytic agent when diesel exhaust gas is passed through the diesel exhaust element. porous filter and such that the ignition temperature or oxidation temperature of the deposited diesel soot is reduced. The catalytic agent is a mixture of alkali metal and cerium oxides. The molar ratio of alkali metal to cerium of the catalytic agent is in the range 0.5 to 5.
