Abstract

A process and associated system for generating a hydrogen product from a feed gas stream comprising hydrogen sulfide. The process includes thermally decomposing hydrogen sulfide present in the feed gas stream into hydrogen gas and elemental sulfur in a thermal decomposition unit. The thermal decomposition unit includes a reactor vessel with a porous susceptor disposed and retained therein and a microwave generation unit positioned and configured to deliver microwave energy to the porous susceptor. Thermally decomposing hydrogen sulfide in the thermal decomposition unit includes directing microwave energy into the porous susceptor to raise the temperature of the porous, susceptor to greater than 1,000° C. and then passing the hydrogen sulfide through the porous susceptor to thermally decompose the hydrogen sulfide and generate a thermal decomposition unit effluent. The process further includes separating the thermal decomposition unit effluent into a sulfur fraction, a hydrogen rich fraction, and a hydrogen sulfide fraction.
