RCO refers to Regenerative Catalytic combustion method, which is referred to as "Regenerative Catalytic Oxidation oxiedition "in English. The principle of RCO regenerative catalytic combustion method is as follows: the first step is the adsorption of the catalyst on VOC molecules, which increases the concentration of reactants; the second step is the catalytic oxidation stage, which reduces the activation energy of the reaction and increases the reaction rate. With the help of catalyst, the organic waste gas can be burned without oxygen at a lower ignition temperature, and decomposed into CO2 and H2O to give off large amount of heat. Compared with direct combustion, it has the characteristics of low ignition temperature and low energy consumption. In some cases, no external heating is needed after reaching the ignition temperature, and the reaction temperature is 250-400°C.
RTO contains no catalyst, RCO contains catalyst;
The operating temperature of RTO is above 760°C, and that of RCO is between 250 °C and 400°C.
RTO may produce NOX secondary pollutants, RCO will not;
RCO has low operating temperature and lower operating cost than RTO.
