TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Components: The reactor apparatus further has input (c) separated or integrated with the input (a), and arranged to receive water or steam that is injected into section of the bed, and the reactions promoted include steam gasification reaction of carbon or carbon monoxide with steam to produce hydrogen. The production of carbon monoxide occurs in lower section of the bed and the production of hydrogen occurs in an upper section of the bed. The reactor vessel has a volume above the carbonaceous bed through which material from input (b) descends and reacts with hot gases rising from the carbonaceous bed to produce products forming portion of a syngas (24) mixture including hydrocarbon compounds of low molecular weight than the input hydrocarbons, hydrogen and carbon monoxide. The gas supply to the input (a) of the reactor apparatus includes carbon dioxide from factory or power plant producing electricity by combustion of carbon or hydrocarbon compounds or a mixture of carbon and hydrocarbon compounds. The carbonaceous bed is further arranged to receive supply of specific oxygen for reaction with carbon to form additional carbon monoxide, and the reactor vessel has exit port(s) for syngas generated in the reactor vessel. The exit port is arranged to supply the syngas to an additional reactor for conversion of syngas to liquid fuel. The additional reactor further includes a Fischer-Tropsch reactor or a Krieg fermentation reactor. The reactor apparatus with the inputs for carbon dioxide gas and biomass solids includes a plasma gasification reactor. The input (a) includes nozzle(s) with plasma torches and the input (b) includes feed port(s) within wall or walls of the reactor vessel. The exit port is proximate an uppermost portion of the reactor vessel. The reactor vessel further comprises a slag and molten metal outlet to allow removal of constituents of input material to the reactor vessel that descend through the carbonaceous bed including metals or metal compounds. The exit port is arranged to supply the syngas to power plant producing electricity (13). The additional reactor for conversion of syngas to liquid fuel, includes an exit port for the liquid fuel generated in the additional reactor. The exit port is arranged to supply the liquid fuel to fuel blending facility. In the region above the carbonaceous material, an aldehyde (CmHnOp) is reacted with x times of water and y times of carbon dioxide, to produce hydrocarbon (Cm1Hn1), x1 times of carbon monoxide, x2 times of hydrogen and y1 times of carbon dioxide, where m1, n1 is an integer smaller than m, n, x1 and x2 is greater than x, y1 is less than y, and m, n and p are characteristic of biomass material. The reactor apparatus has an exit port through which products of the reactions pass. The system has a conduit which leads from the exit port to additional reactor(s) for conversion of gaseous reaction products to liquid hydrocarbon fuels, and further comprises a conduit for gaseous reaction products to be supplied to a power plant converting reaction products to electric power. The power plant converting the reaction products is the combustion source. Preferred Process: The process of reducing atmospheric carbon dioxide further involves converting gaseous hydrocarbon compound which exits the plasma gasification reactor to liquid hydrocarbon compound, blending the resultant hydrocarbon compound with liquid fuel(s) chosen from gasoline, diesel fuel, methanol, ethanol, kerosene, jet fuel, liquefied petroleum gas and/or butane, or supplying gaseous product exiting the plasma gasification reactor to an electric power plant which is source of quantity of gas containing about 50% carbon dioxide. The process further involves supplying additional input gases including oxygen (12) or air, and steam to the bed, and establishing, among the conditions in the PGR, conditions promoting additional reactions in the bed, of carbon with oxygen to form carbon monoxide and, carbon monoxide with steam to form carbon dioxide and hydrogen. The conditions in the PGR produce exiting gases including carbon monoxide and carbon dioxide of quantity in an order of magnitude less than that supplied to the PGR. The conversion process is carried out in Krieg fermentation reactor or Fischer-Tropsch reactor.
