Carbon;2016 Hydrocarbon Processing60CarbonSyngas from H<sub>2</sub>S and CO<sub>2</sub>: An alternative, pioneering synthesis route?Hydrogen sulfide (H<sub>2</sub>S) and carbon dioxide (CO<sub>2</sub>) represent major concerns for the hydrocarbon industry. Both species are contaminants and, since their use as feedstock is minor, are considered troubling byproducts. H<sub>2</sub>S, which mainly derives from oil and gas desulfurization, cannot be vented. Consequently, neutralization is mandatory. Practically every refinery is equipped with a Claus sulfur recovery unit (SRU). Flue gases rich in CO<sub>2</sub> are vented, contributing to climate change; sequestration of CO<sub>2</sub> is technically viable, but remote disposal still remains a questionable end., 01 Jun 2016 00:00:00 GMT
