Abstract
Official abstract text for this publication.
A method that includes forming ethylene from methane including contacting supported-palladium with hydrogen sulfide to form a palladium sulfide catalyst and contacting the palladium sulfide catalyst with methane to form ethylene.
First claim
Opening claim text (preview).
What is claimed: 1. A method of forming ethylene from methane comprising: contacting supported-palladium with hydrogen sulfide to form a palladium sulfide catalyst; and contacting the palladium sulfide catalyst with methane to form ethylene. 2. The method of claim 1 , wherein a support for the supported palladium is selected from the group consisting of MO 2 , cerium oxide (CeO 2 ), silicon oxide (SiO 2 ), magnesium oxide (MgO), Ln 2 O 3 , aluminum oxide (Al 2 O 3 ), Li 2 O, or a combination thereof, where M is Ti, Zr, Hf, or a combination thereof, and Ln is a lanthanide element, Y, Sc, or a combination thereof. 3. The method of claim 1 , wherein the palladium sulfide catalyst includes Pd 16 S 7 . 4. The method of claim 1 , wherein contacting supported-palladium with hydrogen sulfide to form a palladium sulfide catalyst occurs at a temperature in range of from 0 degrees Celsius to 2000 degrees Celsius. 5. The method of claim 1 , wherein contacting the palladium sulfide catalyst with methane to form ethylene occurs at a temperature in range of from 850 degrees Celsius to 2000 degrees Celsius. 6. The method of claim 1 , wherein a volume of the hydrogen sulfide in mL per hour divided by a mass of the supported-palladium in grams has a value in a range of from 6000 mL·g −1 ·h −1 to 30000 mL·g −1 ·h −1 . 7. The method of claim 1 , wherein a volume of the methane in mL per hour divided by a mass of the palladium 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 . 8. The method of claim 1 , further including supplying an inert carrier gas to transport at least one of the hydrogen sulfide and the methane.
