The present invention provides a purification method excellent also in removing particulates or the like from exhaust gas from an internal combustion engine, in particular, a diesel engine or the like. A purification method for exhaust gas from an internal combustion engine, wherein said purification method uses an exhaust gas purification apparatus comprising an oxidation zone installed with an oxidation catalyst supporting both platinum and palladium, and a filtering zone installed with a particulate filter, along exhaust gas flow at the exhaust gas passage of an internal combustion engine, characterized in that hydrocarbon-based liquid is supplied to the inflow side of the exhaust gas of said oxidation zone at the time when 2 to 10 g of particulates per 1 litter of said particulate filter are caught, to raise temperature of said exhaust gas up to equal to or higher than 550° C. by said oxidation catalyst so as to make the residue of said particulate filter combusted; and an apparatus thereof. |
