TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The carbon dioxide is obtained from an exhaust stream from fossil fuel burning power or industrial plant, or a source of natural gas, and the obtained carbon dioxide is reduced by catalytic, photochemical or electrochemical reduction.The carbon dioxide source is the atmosphere and the carbon dioxide is obtained by absorbing atmospheric carbon dioxide onto an adsorbent followed by treating the adsorbent to release the adsorbed carbon dioxide.The adsorbent is treated by heating or by subjecting to reduced pressure to release the adsorbed carbon dioxide.The carbon dioxide is first reduced to carbon monoxide with carbon, reacted subsequently with methanol obtained from the reduction of carbon dioxide, to obtain methyl formate, and the methyl formate is catalytically hydrogenated to produce methanol.The hydrogen needed for the hydrogenation of methyl formate is obtained by decomposing at least some of the formic acid from the reaction mixture.The hydrogen needed for the reduction of carbon dioxide is provided by reacting carbon dioxide with methane or natural gas.The reaction of methane with carbon dioxide provides hydrogen for the hydrogenation of the methyl formate.The process further comprises: dehydrating methanol to produce dimethyl ether; heating dimethyl ether in the presence of an acidic-basic or zeolitic catalysts to form ethylene or propylene; converting ethylene or propylene either to higher olefins, synthetic hydrocarbons or aromatics and their products, for use as feedstocks for chemicals or as transportation fuels; hydrating ethylene or propylene to form ethanol or propanol; preparing an improved diesel fuel by mixing of dimethyl ether with conventional diesel fuel; forming dimethyl carbonate by reaction of the methanol with phosgene or by oxidative carbonylation of the methanol; repairing an improved diesel fuel by mixing dimethyl carbonate with conventional diesel fuel; preparing transportation fuel by adding methanol to gasoline with the fuel having a minimum gasoline content of at least 15 vol.%;
