  • Patent number: 9522864
    Abstract: A method of catalytically preparing a fluid product from solid carbonaceous material is described. In the method, at least one of the following equilibria is established by one or more catalysts: a) CH3OH?CO+2H2, b) CO+H2O?CO2+H2. In some versions, the solid carbonaceous material is woody biomass. Components of the fluid product can include one or a combination of C5-C9 alcohols. In certain versions, the method can he practiced with substantially all of the carbon in the carbonaceous material being converted to the fluid product. Also, in some versions, the fluid product can be prepared with substantially no char formation. The fluid product of various versions can be used directly as fuel or as a reagent for preparing commodity chemicals without the need for separating the fluid product components.

  • Patent number: 8796494
    Abstract: A method of catalytically preparing a fluid product from solid carbonaceous material is described. In the method, at least one of the following equilibria is established by one or more catalysts: a) CH3OH=CO+2H2, b) CO+H2O=CO2+H2. In some versions, the solid carbonaceous material is woody biomass. Components of the fluid product can include one or a combination of C5-C9 alcohols. In certain versions, the method can be practiced with substantially all of the carbon in the carbonaceous material being converted to the fluid product.

  • Publication number: 20060144227
    Abstract: Adsorbents and methods of use thereof are provided. One representative, among others, includes an adsorbent having an alkali metal promoted, mixed trivalent layered double hydroxide (LDH) composition. When the mixed trivalent layered double hydroxide (LDH) composition is heated to a temperature ranging from about 300° C. to 450° C., an the adsorbent having an adsorption capacity of at least 0.8 millimoles of CO2 adsorbed per gram of adsorbent is formed.
