The present invention describes an improved catalytic reactor system with an improved catalyst that transforms CO.sub.2 and low carbon H.sub.2 into low-carbon syngas with greater than an 80% CO.sub.2 conversion efficiency, resulting in the reduction of plant capital and operating costs compared to processes described in the current art. The inside surface of the adiabatic catalytic reactors is lined with an insulating, non-reactive surface which does not react with the syngas and effect catalyst performance. The improved catalyst is robust, has a high CO.sub.2 conversion efficiency, and exhibits little or no degradation in performance over long periods of operation. The low-carbon syngas is used to produce low-carbon fuels (e.g., diesel fuel, jet fuel, gasoline, kerosene, others), chemicals, and other products resulting in a significant reduction in greenhouse gas emissions compared to fossil fuel derived products.

An electrochemical apparatus includes: a reformer that produces a first hydrogen-containing gas by reforming a raw material; a combustor that heats the reformer; an electrochemical device that includes an anode and a cathode, the electrochemical device operating by using the first hydrogen-containing gas supplied to the anode; a first flow rate controller that controls a flow rate of the first hydrogen-containing gas supplied to the anode and a flow rate of a second hydrogen-containing gas supplied from a supply source, the second hydrogen-containing gas being different from the first hydrogen-containing gas; a second flow rate controller that controls a flow rate at which an anode-off gas exhausted from the anode is recycled to the anode and a flow rate at which the anode-off gas is supplied to the combustor; and a controller that controls the first flow rate controller and the second flow rate controller.

A syngas generator is disclosed as an exothermic gas generator that can accommodate high combustion temperatures of a natural gas/oxygen flame. The generator consists of four sections: a heavily insulated combustion chamber, a catalyst chamber, a spray chamber, and a heat exchanger. These four sections may be arranged in series and tightly bolted together to form a gas-tight system. Natural gas, oxygen and steam are supplied to a burner at the inlet end of the combustion chamber. This mixture is ignited and the resulting hot process gas is then fed into a catalyst bed where it reacts with the steam and is converted to carbon monoxide and hydrogen (syngas). The syngas is fed to a Fischer-Tropsch unit to create liquid fuel.
