TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The support is nano-structured fused silica or alumina. The catalyst is provided on a support of a high surface area nano-structured fumed alumina or fumed silica. The catalyst comprises vanadium, titanium, gallium, magnesium, copper, nickel, molybdenum, bismuth, iron, manganese, cobalt, niobium, zirconium, lanthanum, tin or their oxides. The catalyst comprises a single metal catalyst, single metal oxide catalyst, mixed catalyst of a metal and a metal oxide or mixed catalyst of at least one metal oxide and another metal oxide, where the catalyst is optionally provided on an oxide support. The catalyst is nickel oxide or a mixed catalyst of nickel oxide, vanadium(V) oxide, nickel(III) oxide or nickel vanadate. The catalyst is nickel oxide supported on fumed alumina or nickel oxide/vanadium(V) oxide supported on fumed silica.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further comprises: recycling the methanol for use as a fuel or feedstock; subjecting the methanol fuel or products made from the feedstock to reaction conditions to generate carbon dioxide; repeating the capturing, combining, recycling and subjecting steps on the generated carbon dioxide, so that the carbon dioxide produced from the methanol fuel or products made from methanol feedstock also is not emitted to the atmosphere; combusting the coal to produce carbon dioxide; capturing the produced carbon dioxide on an adsorbent; treating the adsorbent to release the captured carbon dioxide therefrom for use in producing methanol or dimethyl ether; reacting carbon dioxide with a suitable hydrocarbon source and steam under steam reforming reaction conditions sufficient to form a mixture of hydrogen and carbon monoxide; reacting carbon dioxide with a suitable hydrocarbon source under dry reforming reaction conditions sufficient to form a mixture of hydrogen and carbon monoxide; combining the hydrogen and carbon monoxide produced in the steam reforming and dry reforming to form a mixture of hydrogen and carbon monoxide in a molar ratio of 2 moles of hydrogen to 1 mole of carbon monoxide for reaction to form methanol; dehydrating methanol by removing water under conditions sufficient to produce dimethyl ether and recycling water from dehydration during subsequent reforming; reacting the dimethyl ether in the presence of an acidic-basic or zeolite catalyst under conditions sufficient to form ethylene or propylene; converting ethylene or propylene under conditions sufficient to produce synthetic hydrocarbons, chemicals or polymers; combusting the produced methanol, optionally in a mixture that includes gasoline, in a power plant that produces energy with the combusted methanol while also generating carbon dioxide and recycling the generated carbon dioxide for producing methanol; and combusting the produced dimethyl ether, optionally in a mixture that includes natural gas and liquefied petroleum gas, in a power plant that produces energy while also generating carbon dioxide and recycling the generated carbon dioxide for producing methanol which in turn produces additional dimethyl ether. The subjecting step generates energy and is performed in a power plant. The carbon dioxide, suitable hydrocarbon source and water are combined in an appropriate molar ratio and reacted in separate steps or in a single step to produce methanol. The adsorbent is treated with sufficient heating, reduced pressure, vacuum and/or gas purge to release the captured carbon dioxide. The absorbent is a polyamino-containing polymer deposited on a nano-structured support having a high surface area. The steam reforming and dry reforming are performed simultaneously in a single bi-reforming step. The methane, steam and carbon dioxide are reacted in a single step in a molar ratio of 3:2:1 to form a mixture of hydrogen and carbon dioxide in a molar ratio of 2:1. The steam reforming and dry reforming are performed simultaneously in a single step over a catalyst at 800-1100 degrees C. Preferred Components: The suitable hydrocarbon source is methane or coalbed methane or natural gas.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polyamino-containing polymer is polyethyleneimine. EXAMPLE - Coal was combusted (with air or pure oxygen) in a power plant and the flue gas that was generated was directed to a capture and purification process rather than being emitted to the atmosphere. Carbon dioxide was removed by being adsorbed or by passing through any suitable adsorbing system containing an adsorbent that was known to efficiently adsorb carbon dioxide. Limiting adsorbent system for removing carbon dioxide included a polyethyleneimine polymer or other polyamino-group containing polymers supported on fumed silica, alumina or other suitable support of nano-structured nature with a high surface area or activity. Carbon dioxide was subsequently desorbed by heating or applying reduced pressure and then was converted chemically to methanol.
