Abstract
Systems and methods for producing methane and sulfur. A first system includes a condensate separation system to separate a feed stream of mixed hydrocarbons, an acid gas removal system to produce a methane product stream and a reactant gas stream of carbon dioxide and hydrogen sulfide and a catalytic reactor configured to react the carbon dioxide and the hydrogen sulfide from the reactant gas stream using a carbon-based catalyst and produce an effluent methane stream, an effluent sulfur stream, and a waste stream. Another system for producing methane and sulfur includes a first separation system to separate water vapor and oxygen to produce a hydrogen sulfide stream, a catalytic reactor configured to react a separated carbon dioxide stream and the hydrogen sulfide stream using a carbon-based catalyst and produce a methane stream and a sulfur stream.
