A system and method for producing methanol and synthetic fuels from waste acid gas streams using a plasma reactor is described in this disclosure. An acid gas stream comprising primarily of H2S and CO2 is fed into a plasma reactor. H2S is converted into H2 and sulfur. Simultaneously, CO is formed by the reverse water gas shift reaction.
