  • Patent number: 8697759
    Abstract: A method for producing methanol from a methane source such as methane from natural (shale) gas by first reacting one equivalent of methane with oxygen from the air to result in complete combustion to produce carbon dioxide and water in a molar ratio of 1:2; then conducting a bi-reforming process with a mixture of methane:carbon dioxide:water having a ratio of 3:1:2 to produce metgas, a mixture of hydrogen and carbon monoxide having a molar ratio of 2:1 to 2.1:1; and finally converting metgas exclusively to methanol. The thus produced methanol can be dehydrated to form dimethyl ether, with water produced being recycled back to the bi-reforming process, if necessary.

  • Publication number: 20130331616
    Abstract: A method for recycling a carbon-containing greenhouse gas emissions such as carbon dioxide and methane (natural gas) or a hydrocarbon homolog thereof. The method includes the steps of capturing the emissions, sequestering them in an underground or undersea storage area, withdrawing them from the storage area after storage therein, and converting them to carbon-containing compounds such as methanol, dimethyl ether and derived products. Greenhouse gases such as carbon dioxide and methane are chemically recycled to provide a permanent and inexhaustible supply of carbon-containing fuels or products, which subsequently can be combusted or used without increasing the carbon dioxide content of the atmosphere. The method is thus effective in neutralizing or reducing the carbon footprint due to human activities related to combustion or use of carbon-containing fuels while providing a repeatedly sustainable carbon source.
