The highly selective conversion of H2S–CO2 to syngas (a mixture of H2 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.

通过非热等离子体和MoS 2 / Al 2 O 3的结合,高选择性地将H 2 S–CO 2转化为合成气

在低温和大气压下,在非热等离子体和MoS 2 / Al 2 O 3混合系统的辅助下,H 2 S–CO 2选择性地转化为合成气(H 2和CO的混合物)。仔细研究了反应条件的影响,包括比能量输入(SEI),进料流速,进料气体组成(H 2 S / CO 2摩尔比)和MoS 2负载。50 h的运行表明MoS 2 / Al 2 O 3在同时H 2 S–CO 2的过程中是稳定的转化为具有优异反应性能的合成气。可以实现较高的CO 2转化率(> 60%)和几乎完全的H 2 S转化率(98–100%)。非热等离子体与MoS 2 / Al 2 O 3结合提供了一种新颖且节能的策略,可以从伴随的H 2 S–CO 2酸性气体中生产合成气,这对于H 2 S排毒和减少CO 2排放具有重要价值。
