TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The hydrogenolysis catalyst comprises at least one transition metal comprising nickel, cobalt, osmium, iridium, rhodium, ruthenium, rhenium and iron on a metal oxide support.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process further comprises: separating the first quantity of methane and the second quantity of methane from other components within the gaseous feed stream to form a purified natural gas feed stream; and sending the gaseous feed stream to a reactor to convert the carbon dioxide and carbon monoxide to methane. The first quantity of methane is separated from the gaseous feed stream before the gaseous feed stream is sent to the conversion unit. In the process, at least 50 (preferably 90) % of the ethane and propane are converted to methane. The portion of the carbon monoxide and carbon dioxide are converted to methane within the conversion unit. In the process, after the hydrogenolysis reaction takes place, carbon oxides are added to a resulting gaseous stream and then the resulting gaseous stream is subjected to a methanation reaction to react the carbon oxides with hydrogen to produce a third quantity of methane. The hydrogenolysis reaction has a light-off temperature of 300-375 degrees C. The temperature for conversion of the higher carbon hydrocarbons than methane to methane is 2500-600 degrees C. The gaseous feed stream comprises 10-25 (preferably 20-25) vol.% combined ethane and propane. The gaseous feed stream is sent to at least two of the conversion units sequentially. The gaseous feed stream is divided into a first gaseous feed stream and a second gaseous feed stream prior to passing to the at least two of the conversion units, where the first gaseous feed stream is heated to the hydrogenolysis reaction temperature, then the first gaseous feed stream is sent to a first conversion unit to produce a first enhanced methane stream, then the first enhanced methane stream is cooled upon being mixed with the second gaseous feed stream to form a combined gaseous feed stream, and then the combined gaseous feed stream is sent to a second conversion unit to be converted to a second enhanced methane stream. The purified natural gas stream is sent into a natural gas pipeline to be transported. Preferred Components: The hydrogen and the ethane are present in a molar ratio of 0.8:1-10:1. The feed stream further comprises carbon oxides; and higher hydrocarbons than ethane. The natural gas feed stream is a product of thermal treatment of oil or carbon containing rocks or sand.
