TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process (M1) further involves: removing contaminants from the natural gas stream; passing at least a portion of the reactive products to a separator in which some carbon dioxide is removed; and passing at least a portion of the reactive products and hydrogen to a separator in which at least some of the hydrogen is removed. The process further involves: conveying a portion of the hydrogen to a fuel cell or turbine; providing an oxygen stream to the fuel cell or turbine; and reacting the hydrogen with the oxygen in the fuel cell or turbine to produce electricity. The fuel cell or turbine produces heat. The process (M1) further involves: heating the water produced in the fuel cell with the heat produced in the fuel cell to generate steam; generating electricity from the steam; and passing at least a portion of the reactive products to a separator in which some carbon monoxide is removed. The natural gas stream is preheated by a device selected from: electric arc, resistance heater, plasma generator, fuel cell, combustion heater, and/or heat exchanger. The pressure of the natural gas stream is 1-20 bar. The natural gas stream is preheated to 400-1800K. A portion of the natural gas is maintained at at least 400K for 0.1-100 (preferably 0.2-10) milliseconds. The catalyst in the catalytic liquefaction reactor comprises an acid catalyst. The catalytic liquefaction reactor operates at 300-1000K. The reactive products are quenched by a device selected from: a Joule-Thompson expander, nozzle, turbo expander, water spray, hydrocarbon spray, oil spray, steam, boiler, and/or heat exchanger. The reactive products are quenched by mixing the product stream with vapor or liquid hydrocarbons. The process further involves: (a) separating a portion of the hydrogen from the hydrocarbon liquids; providing oxygen to a fuel cell or turbine; and reacting the hydrogen with the oxygen in the fuel cell or burning the hydrogen with the oxygen in the turbine to produce electricity; (b) separating a gas or vapor from the hydrocarbon liquids and recirculating at least a portion of the gas or vapor to the reactor; (c) separating a gas or vapor from the hydrocarbon liquids and recirculating at least a portion of the gas or vapor to the catalytic liquefaction reactor; separating a gas or vapor from the hydrocarbon liquids and using at least a portion of the gas or vapor stream to at least partially quench the reactive products; (d) separating a liquid stream from the hydrocarbon liquids; and using at least a portion of the liquid stream to at least partially quench the reactive products; (e) introducing steam, water, or both to the reactor; (f) heating the steam, water, or both prior to its introduction to the reactor by a device selected from an electric arc, resistance heater, plasma generator, fuel cell, combustion heater, and/or heat exchanger; (g) separating a syn gas stream from the process; (h) conveying at least a portion of the syn gas stream to subsequent processing or conversion; (i) separating at least some carbon dioxide from a least a portion of the syn gas stream; (j) separating hydrogen from a least a portion of the syn gas stream; (k) using the hydrogen to generate electricity directly or indirectly; (l) separating a gas or vapor from the process and using the gas or vapor as fuel or to generate electricity; and (m) separating a liquid or slurry from the process and using the liquid or slurry as fuel.
