In Situ Hydrogenation and Desulfurization of CS₂ by Mg-Based Hydrogen Storage Material:Products and Mechanism Analysis

Abstract:

Mg-based hydrogen storage material was prepared by ball milling, and then the material was used to react with CS₂. The morphology and hydrogen desorption properties of the hydrogen storage material as well as the CS₂ hydrogenation product were analyzed. Results show that in situ hydrogenation and desulfurization of CS₂ happens with the MgH₂ in the hydrogen storage material as hydrogen donator and desulfurizer at 300 °C and ordinary pressure, and MgS, CH₄ and H₂S are generated from the reaction. There is a coupling relationship between dehydrogenation of the hydrogen storage material and hydrogenation of CS₂. The addition of nickel and molybdenum show negative effect on the sulfur fixation capability of the Mg-based hydrogen storage material though they could decrease the dehydrogenation temperature of the material.
