Forming ethylene

摘要

Form ethylene via a method that includes vaporizing elemental sulfur, providing a metal sulfide catalyst, and contacting the metal sulfide catalyst with a mixture of methane and the vaporized elemental sulfur to form ethylene. The mixture has a methane to sulfur molar ratio greater than 1.2:1.0.

1. A method of forming ethylene comprising:
vaporizing elemental sulfur; providing a metal sulfide catalyst; supplying an inert gas to transport a mixture of methane and the vaporized elemental sulfur to the metal sulfide catalyst; and contacting the metal sulfide catalyst with the mixture of methane and the vaporized elemental sulfur to form ethylene, wherein the mixture has a methane to sulfur molar ratio greater than 1.2:1.0 and a mass of the methane in grams per hour divided by a mass of the metal sulfide catalyst in grams has a value in a range of from 6000 mL·g−1·h−1 to 30000 mL·g−1·h−1.
