Catalytic Effect on Thermal Decomposition of Hydrocarbon Fuel within a Tube Simulating a Cooling Channel

Regenerative cooling using hydrocarbon fuel requires thermal decomposition to increase heat absorption, but a high temperature is required initiate and catalysis expected enhance at lower regime. The effects of on coking normal-dodecane methyl-cyclo-hexane within tube heater were experimentally investigated. Platinum (Pt) was spread the inner surface stainless tube, heated target values an electric heater. Decomposed components accumulated analyzed, input evaluated based gradient tube. results compared with those without coating show that Pt-coating lowered onset by 100 K for both fuels. Additionally, absorption per decomposed amount affected sizably reduced generation.
