Question

Coal gasification produces hydrogen sulfide and carbon dioxide as undesirable by products. Of these, the hydrogen sulfide can be converted to elemental sulfur, which can then be sold for profit. This conversion is often accomplished through the following set of chemical reactions: A plant equipped to conduct these reactions is fed a mixture of methane, hydrogen sulfide and air. Synthesize a process that uses only the raw materials present in this feed and produces sulfur, but does not produce either sulfur dioxide or carbonyl sulfide (COS). If it is possible to synthesize more than one process that meets the given constraints, show a few of these processes. Show all your work.
