Duane A Goetsch, Geoffrey R Say: Synthesis gas preparation and catalyst therefor. Exxon Research and Engineering Company, Jay Simon, October 31, 1989: US04877550 (28 worldwide citation)

Light hydrocarbons, e.g., methane are converted to synthesis gas at elevated temperatures and pressures in the presence of a particulate catalyst, e.g., Ni/Al.sub.2 O.sub.3. The conversion of feed to synthesis gas is preserved by rapidly cooling the reaction production to a temperature below that wh ...
