Abstract
Temperature range enabling combustion of high concentration hydrocarbon is enlarged, or high temperature gas is rapidly supplied to a latter part catalyst. Provided is a method for purification of exhaust gas from an internal combustion engine, by using a catalyst for increasing temperature of exhaust gas from an internal combustion engine, wherein hydrocarbon from 1,000 to 40,000 ppm by volume, as converted to methane, to the exhaust gas, is introduced at the upstream side of the catalyst for increasing temperature, along flow of the exhaust gas inside a passage of exhaust gas from the internal combustion engine.
