Abstract: Catalytic heater model in the form of a tubular reactor, in the tube space of which heat is removed using a high-boiling coolant was elaborated. Kinetic parameters of methane oxidation rate constant on a manganese-alumina catalyst (pre-exponential factor and activation energy) that were used to calculate the observable reaction rates on grains of various shapes and sizes were determined. It was demonstrated that the maximum specific heat power of a catalytic heater is 19.25 kW/m3; it can be obtained by applying the catalyst in the form of rings with dimensions of 5 × 5 × 2 mm, under the following conditions: inlet methane concentration of 3 %, inlet temperature of 500 °C, coolant temperature of 400 °C, tube length of 1 m, tube diameter of 8 cm, linear rate of 0.05 m/s. With such parameters, the degree of methane conversion is greater than 98 %, and the maximum temperature does not exceed 770 °C, which meets accepted limitations.
