NOVELTY - A system (100) comprises reciprocating water gas shift reactor (106), where the reactor is operative at speeds down to about 1 revolution per minute, while converting carbon monoxide and steam into carbon dioxide and hydrogen; or a hydrogen engine, or fuel cell with electric motor, and water gas shift reactor, where hydrogen engine, or fuel cell with electric motor is in operative to drive water gas shift reactor at speeds down to about 1 revolution per minute; and operative to convert carbon monoxide and steam, into carbon dioxide and hydrogen.    USE - As system (claimed); for converting waste into energy; for producing fuel for combustion engines; and for production of synthetic fuels for use in automobiles, factories, and airplanes.    ADVANTAGE - The system is able to dispose off some of the waste matter that is generated by living beings in a manner that protects the environment; recycles some of this waste into energy so as to reduce the cost of energy generation as well as to recover some of the energy that is expended in the manufacturing of products that ends up as waste; and generates energy from waste that is discarded to landfills in a manner that does not further degrade the environment, and produces fuel for combustion engines. The system allows production of synthetic fuels for use in automobiles, factories, airplanes, and the like. The system increases the amount of hydrogen so that fuels can be produced inexpensively and efficiently; and uses waste and other carbonaceous materials as feedstock to produce large quantities of liquid and gaseous fuels, while minimizing carbonaceous emissions to the atmosphere.    DETAILED DESCRIPTION - A system (100) comprises a reciprocating water gas shift reactor (106), where the water gas shift reactor is operative at speeds down to about 1 revolution per minute, while converting carbon monoxide (CO) and steam (H2O) into carbon dioxide (CO2) and hydrogen (H2); or a hydrogen engine, or fuel cell with electric motor, and water gas shift reactor, where the hydrogen engine, or fuel cell with electric motor is in operative to drive the water gas shift reactor at speeds down to about 1 revolution per minute; and operative to convert carbon monoxide (CO) and steam (H2O), into carbon dioxide (CO2) and hydrogen (H2); or a reciprocating internal combustion engine, where the internal combustion engine is operative to boil fluids with combustion exhaust gases to provide additional engine power output. The reciprocating water gas shift reactor is operative to convert natural gas or methane (CH4) and steam (H2O), into carbon dioxide (CO2) and hydrogen (4H2). The reciprocating water gas shift reactor is operative to convert synthesis gas (CO+H2) and steam (H2O), into carbon dioxide (CO2) and hydrogen (2H2). The reciprocating water gas shift reactor is operative to convert synthesis gas (CO+H2) and steam (H2O), into liquid fuel hydrocarbon (HC) plus alcohols and acids. The reciprocating water gas shift reactor is operative to function without being supplied with pressurized gas, or pressurized water. The reciprocating water gas shift reactor is operative to function without being supplied with heated gas or heated water. The reciprocating water gas shift reactor is a four stroke cycle unit, a six stroke cycle unit or integral 8 stroke cycle unit or is a 4 stroke split cycle unit, or 6 stroke split cycle unit. The hydrogen engine and water shift reactor operate on 4-stroke, 6 stroke, 4 stroke split or 6 stroke split cycle. The reciprocating water gas shift reactor is operative to boil fluids with combustion exhaust gases to provide self driving power. The reciprocating internal combustion engine is split cycle reciprocating internal combustion engine. The internal combustion engine and water gas shift reactor are operative to function with alternating power, and water gas shift reaction, from the same cylinders. The reciprocating water gas shift reactor is operative to function with a synthesis gas to liquid fuel plant (108) and the inputs and outputs of the water gas shift reactor is operative to synergistically match those of the syngas to liquid fuel plant. An INDEPENDENT CLAIM is included for a method involving displacing a reciprocating piston to draw carbon monoxide into a cylinder; compressing the carbon monoxide; injecting steam and/or water into the cylinder; mixing the carbon dioxide and stream to have fluid communication with a catalyst in the cylinder; converting the carbon monoxide and steam into carbon dioxide, and hydrogen; and discharging carbon dioxide and hydrogen from the cylinder. The natural gas or methane is drawn into the cylinder to discharge carbon dioxide and hydrogen. The synthesis gas is drawn into the cylinder to discharge carbon dioxide and hydrogen. The synthesis gas is drawn into the cylinder to discharge into liquid fuel hydrocarbon (HC) plus alcohols and acids.
