Catalytic partial oxidation (CPO) of methane is a potential technologyfor conversion of methane into synthesis gas, because the process operatesautothermally with millisecond residence times and at high temperatures with noexternal heating. A dedicated reactor setup withcapillary species sampling and temperature probes was used to measure highresolution (~100 �m) species and temperature profiles in high temperature (T> 500 �C) and high pressure (1 < p < 50 bar) CPO of methaneon platinum. Three different catalyst systems have been investigated usingsyngas relevant reactant mixtures. (A) Platinum nanoparticles supported onreticulated a-alumina foams, (B) platinum nanoparticles supported on a-aluminaspheres, and (C) a polycrystalline platinum tube. The spatial profiles provide information on reaction pathways, distinctzoning effects in the catalyst beds, impact of mass and heat transport as wellas gas phase chemistry. In-situ Raman experiments contribute to ourconceptional understanding of the reaction mechanism.
