The highly selective conversion of H2S-CO2 to syngas (a mixture of H-2 and CO), which assisted by non-thermal plasma and MoS2/Al2O3 hybrid system, was obtained at low temperature and atmospheric pressure. The effects of reaction conditions, including the specific energy input (SEI), feed flow rate, feed gas composition (H2S/CO2 molar ratio), and MoS2 loading were carefully investigated. The 50-h-long runs indicate that MoS2/Al2O3 was stable in the course of simultaneous H2S-CO2 conversion into syngas with excellent reaction properties. High CO2 conversion (>60 %) and almost full H2S conversion (98-100 %) can be achieved. The non-thermal plasma combined with MoS2/Al2O3 offers a novel and energy-efficient strategy to produce syngas from concomitant H2S-CO2 acid gases with great value for detoxifying H2S and reducing CO2 emissions.
