NOVELTY - A pressurized source hydrogen and source oxygen are produced from water using electrical energy generated by an electrolyzer. The reverse water gas shift reactants is preheated using a reverse water gas shift-gas recuperator for reverse water gas shift reaction in a catalytic reactor, and reverse water gas shift product is cooled for water condensation. The carbon dioxide and hydrogen is partially converted to carbon monoxide and water. The carbon monoxide from the reverse water gas shift products is separated.    USE - Production of carbon monoxide using electrical energy, water, and recovered carbon dioxide from effluent carbon dioxide, chemical process, natural gas, water components and atmosphere.    ADVANTAGE - The method enables production of carbon monoxide efficiently and economically.    DETAILED DESCRIPTION - A pressurized source hydrogen and source oxygen are produced from water using electrical energy generated by an electrolyzer. The reverse water gas shift reactants is preheated using a reverse water gas shift-gas recuperator for reverse water gas shift reaction in a catalytic reactor, and reverse water gas shift product is cooled for water condensation. The preheated reverse water gas shift reactant is further heated in a heat exchanger. The carbon dioxide and hydrogen in reverse water gas shift reactants is partially converted to carbon monoxide and water in reverse water gas shift reactor product at 550 degrees K or more and 0.2 MPa or more using a reverse water gas shift reactor. The water from the cooled reverse water gas shift products is condensed. The carbon monoxide from the reverse water gas shift products is separated. The un-reacted hydrogen, carbon dioxide, un-separated carbon monoxide, and un-separated water obtained through the reverse water gas shift-gas recuperator and other components are recycled. INDEPENDENT CLAIMS are included for the following:    (1) renewable Fischer Tropsch synthesis process; and    (2) multi-tubular, fixed-bed reverse water gas shift reactor.
