TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The carbon-containing gas emissions are used as the hydrogen source in the reductive conversion of carbon dioxide (dry reforming) or with a suitable combination with steam reforming (wet reforming) to provide a 1:2 molar mixture of carbon monoxide and hydrogen, which subsequently can react to produce exclusively methanol. The carbon dioxide is captured from flue or off-gases of coal or other fossil fuel burning plants, geothermal power facilities, cement, aluminum or other industrial plants or factories, industrial or agricultural wastes, byproducts of natural gas production, the air or atmosphere. The method (I) further comprises: adsorbing atmospheric carbon dioxide on an adsorbent and treating the adsorbent to release the adsorbed carbon dioxide from it; chemically converting the withdrawn carbon dioxide into methanol by hydrogenative reductive processes; forming dimethyl carbonate by reaction of the methanol with phosgene or by oxidative carbonylation of the methanol; dehydrating the methanol under conditions sufficient to produce dimethyl ether; converting the methanol or dimethyl ether to ethylene or propylene in the presence of a catalyst; converting the ethylene or propylene to higher olefins, synthetic hydrocarbons or aromatics, or products from them, for use as feedstocks for chemicals or as transportation fuels; and hydrating the ethylene or propylene to form ethanol, propanol or isopropanol. Preferred Components: The carbon-containing gas emissions are methane, natural gas or their hydrocarbon homologs. The carbon-containing gas emission is carbon dioxide, which is emitted from combustion or use of carbon-containing fuel. EXAMPLE - Industrial or naturally released carbon-containing greenhouse gases, primarily carbon dioxide or methane (or its homologs), were captured and separated. Carbon dioxide was separated using suitable adsorbents comprising nanostructured, supported polymeric absorbents containing alkanolamine or nitrogen, preferably polyethyleneimine. The gases were purified from accompanying toxic or other harmful impurities. The separated greenhouse gases were then sequestered (stored) in underground facility, including depleted oil fields, coal beds or other suitable geological formations, compressed and injected into the depths of the sea or lake for storage. The stored carbon dioxide or methane was withdrawn from the storage facility by raising the temperature or decreasing the pressure. The carbon dioxide was withdrawn from the same pipelines used to introduce the carbon dioxide into the cavern. The withdrawn carbon dioxide or methane was transported to a recycling facility, and then was converted by hydrogenative (carbon dioxide) or reformative (methane) conversions, to methanol, dimethyl ether, or their derived products.
