| 摘要 |
This exhaust gas treatment system (1) is provided with an oxidation reactor (10), a heat exchanger (15), a heater (20), a thermometer (29) and a heating amount controller (21). The oxidation reactor (10) is internally filled with a catalyst (11) wherein Pt is supported by a titania carrier, and oxidizes carbon monoxide contained in an exhaust gas (EX). The heat exchanger (15) heats the gas before oxidation (EXb), which is the gas before being treated by the oxidation reactor (10), by performing heat exchange between the gas before oxidation (EXb) and the oxidized gas (EXa), which is the gas after being treated by the oxidation reactor (10). The heater (20) heats the gas before oxidation (EXb) after passing through the heat exchanger (15). The heating amount controller (21) controls the amount of heating by the heater (20) so that the temperature detected by the thermometer (29) is within a predetermined temperature range. |
