โœฆ Synopsis

The partial oxidation of methane to synthesis gas has been studied using several different catalytic systems: Fixed-bed, a monolithic type catalyst, and a Pt gauze. The monoliths were impregnated with Ni and Pd (5 wt.% metal) whereas 5% Ni/ AI203 was used in the fixed-bed reactor. The experiments were carded out at 500--800ยฐC, 1 bar and with space times in the range of 0.14--0.0002 s. The measured temperature profiles for both the fixed-bed and the monolithic reactor indicate that the reaction consists of a total combustion of some of the methane followed by the endothermic reforming reactions and the water-gas shift reaction. Selectivities close to equilibrium composition were obtained in most cases except at the very low space times. Only small amounts of H2 were observed in the product gas from the Pt gauze catalyst.
