Open the CIPO recordAbstract From the Canadian patent
Light hydrocarbons e.g. methane are con-, verted to synthesis gas at elevated temperatures and pressures in the presence of a particulate catalyst e.g. Ni/Al2O3. The conversion of feed to synthesis gas is preserved by rapidly cooling the reaction production to a temperature below that which favors the back reaction of carbon monoxide and hydrogen to form methane.
