Abstract

The conversion of Hydrogen Sulfide into H₂ and Sulfur (H₂S → H₂ + S) is beneficial from both environmental and energy perspectives. The two-step thermochemical decomposition of H₂S is considered one of the most promising technologies for Hydrogen production. This work investigates the chemical kinetics of the two-step thermochemical decomposition of H₂S using Nickel Sulfide and studies the key parameters that affect the overall cycling process and H₂S conversion efficiency. Gas-phase and surface-phase kinetics of the two-step thermochemical decomposition of H₂S models were developed in CHEMKIN software. The formulated model results were found to be consistent with the experimental results.
