  • Publication number: 20140345546
    Abstract: A Coal-to-Liquid Fuels production process by which carbon dioxide (CO2) exhaust by-products are significantly reduced, if not eliminated, through a system comprising the generation of a first hydrogen (H2) product and carbon from coal and generating carbon monoxide (CO) by reacting the Carbon (C) with CO2. A second hydrogen (H2) product is generated through catalyzation of water, methane reformation, electrolysis of water, or other reaction processes. Carbon monoxide (CO) is reacted with the first and second hydrogen (H2) products to form a first hydrocarbon group having Olefins. The first hydrocarbon group, as Olefins, are further reacted to form C1-40 alcohols, Kerosene, Gasoline, Diesel Fuel, and Jet Fuel, and combinations thereof. At least a portion of the finished fuel blends are optionally used to generate electricity for use in the fuels production process or for distribution to an external power grid.

    Abstract: The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises greater than 40 vol. % of the extracted gas. The extracted gas is scrubbed with a wash effective to produce a washed extracted gas containing less carbon dioxide than the extracted gas and at least 20 vol. % carbon dioxide. The washed extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid methanol product.

The apparatus includes, in advance of the pyrolysis subsystem, an ash removal station wherein the ash is removed from the coal, a crushing station wherein the ash free coal is crushed to produce a crushed coal, and a desulfurizing steam station wherein the sulfur is substantially removed from the crushed coal. The apparatus further includes a closed fractionizing tower that is operably associated with the pyrolysis subsystem and into which the pyrolysis products from the pyrolysis subsystem pass.

    Abstract: The present invention relates to a method of producing methanol from a methane source by oxidizing methane under conditions sufficient to a mixture of methanol and formaldehyde while minimizing the formation of formic acid and carbon dioxide. The oxidation step is followed by treatment step in which formaldehyde is converted into methanol and formic acid which itself can further be converted into methanol via catalytic hydrogenation of intermediately formed methyl formate.
