In this study, the microwave-induced Co-Mo and Ni-Mo catalysts were combined with a high-dielectric-constant medium to absorb microwave energy and convert it into the heat energy required for syngas production. The microwave conditions were a microwave power of 450 W and a total microwave time of 210 min with the volume ratios CH_4/air =1:2 (partial oxidation) and CH_4/CO_2 = 2:1 (dry reforming reaction). The results showed that the average yields of H_2 and CO were 43 and 35.7% in the partial oxidation reaction with Ni-Mo as catalyst, whereas those in the dry reforming reaction were 44.4 and 24.9%, respectively. On the other hand, with Co-Mo as the catalyst, the average yields of H_2 and CO were 50.7 and 35.9% in the partial oxidation reaction, whereas those in the dry reforming reaction were 62.6 and 40.6%, respectively. Owing to the high activity of the Ni-Mo catalyst, it is easier to shield the metal coated on the surface by coke deposition. As the reaction time proceeds, the activity of the Ni-Mo catalyst decreases, and the syngas yield is reduced. Therefore, it is feasible and innovative to combine microwave-induced Ni-Mo and Co-Mo catalysts with a high-dielectric-constant medium to absorb and convert microwave energy into heat energy to produce syngas.
