Zusammenfassung:The invention relates to a heating auxiliary system and process for thermocatalytic reaction, which comprises the following steps: wastewater in a raw water tank enters a four-stage heat exchanger through a feeding pump, and a first-stage heat exchanger provides a heat source for the four-stage heat exchanger to carry out first-stage heating on the wastewater; the wastewater enters a first-stage heat exchanger, and hot water in a hot water tank is recycled through a circulating hot water pump to perform second-stage heating on the wastewater; the steam enters a second-stage heat exchanger, and provides a heat source for the second-stage heat exchanger for third-stage heating; detecting the temperature and adjusting the temperature of the wastewater at the outlet end of the secondary heat exchanger to reach a thermocatalytic reaction temperature range; the wastewater is subjected to a thermocatalytic reaction in the reactor. The heat exchange system has the beneficial effects that the heat exchange system capa
