  • Publication number: 20120142522
    Abstract: A carbonaceous feedstock to alcohol conversion process in which carbon dioxide is removed from the syngas stream issuing from a feedstock reformer, to yield a carbon dioxide depleted syngas stream including hydrogen, carbon monoxide and methane. This carbon dioxide depleted syngas stream is then passed through a Fischer-Tropsch reactor ultimately yielding a mixed alcohol product which is preferably largely ethanol. The removed carbon dioxide stream is passed through a methane reformer along with methane, which is produced in or has passed through a Fischer-Tropsch reactor, to yield primarily carbon monoxide and hydrogen. The carbon monoxide and hydrogen stream from the methane reformer are passed through the alcohol reactor. Also disclosed are a unique catalyst, a method for controlling the content of the syngas formed in the feedstock reformer, and a feedstock handling system.

  • Publication number: 20120059208
    Abstract: A catalyst for oxidative dehydrogenation of organic compounds is provided by forming a solution of catalyst precursor components comprised of Fe+3 and Zn+2 cations and at least one other modifier element cation in water to form an aqueous solution of the catalyst precursor components. The modifier element cation has a standard reduction potential of from greater than about ?2.87 E° (V) to less than about ?0.036 E° (V) with a valence of +2. A base is separately and simultaneously added to the aqueous solution in amounts to maintain the pH of the aqueous solution at a pH of from about 8.5 to about 9.5 as the catalyst precursor components. The catalyst precursor components are allowed to react and precipitate out of solution as a precipitate. The resulting precipitate is calcined to form a modified zinc ferrite catalyst compound.

  • Patent number: 8110708
    Abstract: Ruthenium/activated charcoal (Ru/AC) treated with synthesized nano-ZnO (n-ZnO) is used for the first time as a novel composite catalyst in one-step self-condensation of acetone (DMK) to methyl isobutyl ketone in the gas phase. The DMK self-condensation was performed under atmospheric pressure, in a tubular glass fixed-bed microreactor, under DMK and H2 continuous flow at temperature in the range of 523 to 648 K. Addition of n-ZnO to Ru/AC resulted in a pronounced increase in the degree of dispersion of Ru and in the acidic/basic sites concentration ratio. For the one-step synthesis of MIBK at 623 K, the composite catalyst with 2.5 wt % Ru loading was an active and selective bi-functional composite catalyst with balanced acid/base and hydrogenation properties. At 523 K, isopropyl alcohol, product of DMK-direct hydrogenation, was produced in high selectivity for instantly investigated composite catalyst.
