Comparative study on the performance of microwave-assisted plasma DRM in nitrogen and argon atmospheres at a low microwave power

다국어 초록 (Multilingual Abstract)

Dry reforming of methane (DRM) is an attractive route to convert CH4 and CO2 into syngas (a mixture ofCO and H2). In this work, the performance of microwave-assisted DRM at atmospheric pressure (interms of CH4 and CO2 conversions, H2 and CO selectivities, H2 and CO yields, and H2 to CO ratio) isstudied as functions of additive gasflow rate, microwave power, CO2 to CH4 inlet supply ratio, andreaction time. Two additive gases were used, i.e., nitrogen and argon. Microwave-assisted DRMexperiments in both gases show identical trend of conversions, selectivities, yields, and product ratio.
DRM performances in both additive gases atmosphere were stable for up to 8 h. Under the sameoperating conditions, using Ar as an additive gas, however, led to higher H2 and CO selectivities andyields and thus, higher H2 to CO ratio relative to using N2 as an additive gas. Maximum CH4 and CO2conversions of 79.35% and 44.82%, H2 and CO selectivities of 50.12% and 58.42%, H2 and CO yields of39.77% and 32.89%, and H2 to CO ratio of 0.86 were obtained at 700 W and N2, CO2, and CH4 flow rates of1.5, 0.4, and 0.2 L min 1, respectively.
