20120241327 | MATERIALS AND DESIGN FOR AN ELECTROCATALYTIC DEVICE AND METHOD WHICH PRODUCES CARBON NANOTUBES AND HYDROCARBON TRANSPORTATION FUELS - The present teachings are directed toward an electrocatalytic cell including a barrier, having at least a first side and a second side opposite the first side, comprising a material permeable to oxygen ions and impermeable to at least CO | 09-27-2012 |
20120245236 | FISCHER-TROPSCH CATALYSTS CONTAINING IRON OR COBALT SELECTIVE TOWARDS HIGHER HYDROCARBONS - Cryptomelane-type manganese oxide octahedral molecular sieves (OMS-2) supported Fe and Co catalysts are utilized in a method for producing hydrocarbons by a Fischer-Tropsch mechanism. The hydrocarbon producing method includes providing a catalyst of a manganese oxide-based octahedral molecular sieve nanofibers with an active catalyst component of at least one of iron, cobalt, nickel, copper, manganese, vanadium, zinc, and mixtures thereof, and further containing an alkali metal. The formation of iron carbides and cobalt carbides by exposing the catalyst to conditions sufficient to form those carbides is also taught. After the catalyst has been appropriately treated, a carbon source and a hydrogen source are provided and contacted with the catalyst to thereby form a hydrocarbon containing product. The catalyst have high catalytic activity and selectivity (75%) for C2+ hydrocarbons in both CO hydrogenation and CO2 hydrogenation. Highly selective syntheses of high value jet fuel, C2-C6 alkenes, C2-C6 carboxylic acids; α-hydroxylic acids and their derivatives have been realized by tuning the oxidation ability of OMS-2 supports and by doping with Cu | 09-27-2012 |
20120322645 | METHOD OF SYNTHESIZING MULTI-IPHASE OXIDE CERAMICS WITH SMALL PHASE DOMAIN SIZES - Nanocomposites of multi-phase metal oxide ceramics have been produced from water soluble salts of the resulting metal oxides by a foaming esterification sol-gel method. The evolution of volatile gases at elevated temperature during the esterification reaction causes the formation of a foam product. Nanocomposites of multi-phase metal oxide ceramics have also been produced by a cation polymer precursor method. In this second method, the metal cations are chelated by the polymer and the resulting product is gelled and foamed. Calcination of the resulting foams gives nanocomposite powders with extremely fine, uniform grains and phase domains. These microstructures are remarkably stable both under post-calcination heat treatment and during consolidation by hot-pressing. | 12-20-2012 |
