Methane conversion was carried out in a presence of a catalyst within a dielectric-barrier discharge reactor. Temperature programmed reduction (TPR) and plasma-assisted reduction (PAR) was studied to reduce the supported metal catalysts. Prepared catalyst was successively reduced by PAR. The selectivity of C 2H 6, C 2H 4 and C 2H 2 was higher among the produced hydrocarbons when the methane conversion was carried out in the absence of a catalyst. In the presence of Pt and Co catalyst, the main products of plasma catalytic reaction were light alkanes such as C 2H 6, C 3H 8 and C 4H 10. The plasma catalytic reaction showed positive characteristics to produce light alkanes when Pt and Co catalyst were used after PAR. PAR was an effective method to reduce supported metal catalyst.
