<P>PROBLEM TO BE SOLVED: To provide a method for reactivating catalyst for purifying exhaust gas, capable of reactivating a catalyst for purifying exhaust gas with a simple method. <P>SOLUTION: A poisonous substance sticking to the catalyst converter 3 is removed by injecting weak acidic cleaning liquid from the upstream side of the catalyst converter 3. Specifically, the catalyst converter 3 can be reactivated by a simple operation for injecting weak acidic cleaning liquid into an exhaust pipe 2. As a result, the catalyst converter 3 can be reactivated by a simple method and so as to exhibit more excellent activity compared to a conventional method for reactivating the catalyst for purifying exhaust gas. <P>COPYRIGHT: (C)2013,JPO&INPIT |
