12-CS2 production from methane reforming with H2S

Abstract

Methane reforming in the presence of hydrogen sulfide (H2SMR) is not only conspicuous in terms of producing valuable material but also because of its advantages in obtaining hydrogen as a clean fuel. Substitution of traditional hydrogen production processes such as methane steam reforming (MSR), elimination of natural gas amine–based H2S removal, and sulfur recovery processes have attracted much attention. The current hydrogen production is associated with consuming energy that is usually supplied by burning fossil fuels. Thus, producing hydrogen by current high greenhouse gas emitter methods seems not to be a rational approach to benefit from this clean energy source. Additionally, H2SMR with the potential of producing four moles of hydrogen and one mole of CS2 from methane could be a promising alternative as providing the opportunity to benefit from producing cleaner fuels and simultaneously making CS2 that is used for the production of more valuable products. This chapter reviews the recent progress in CS2 production from methane reforming in the presence of H2S and brings the effect of dominant parameters on this process.
