1. A method comprising:
flowing a feed stream to a catalytic reactor comprising a non-thermal plasma and a catalyst, the feed stream comprising hydrogen sulfide and carbon dioxide, the catalyst comprising a zeolite-based catalyst;
contacting the feed stream with the catalyst in the presence of the non-thermal plasma at a reaction temperature that is in a range of from about 20 degrees Celsius (° C.) to about 900° C., thereby converting the hydrogen sulfide and the carbon dioxide in the feed stream to produce a product comprising a hydrocarbon and sulfur, the hydrocarbon having more carbon atoms than ethane; and
separating the product into a product stream comprising the hydrocarbon and a sulfur stream comprising the sulfur.
