  • Patent number: 9649623
    Abstract: The present invention relates to a process of preparing of a phosphorus-containing phosphorus-alumina support by a sol-gel method and a cobalt/phosphorus-alumina catalyst where cobalt is supported onto the phosphorus-alumina support as an active ingredient. The phosphorus-alumina support is prepared by a sol-gel method and has wide specific surface area with bimodal pore size distribution and high cobalt dispersion, thereby enabling to increase heat and mass transfer, stabilize the structure by modifying the surface property of alumina and decrease the deactivation rate due to the reduced oxidation of cobalt component during the F-T reaction. When Fischer-Tropsch reaction (F-T) is conducted on the catalyst, the catalyst maintains a superior thermal stability, inhibits the deactivation due to water generation during the F-T reaction and also causes relatively high conversion of carbon monoxide and stable selectivity of liquid hydrocarbons.

    Abstract: A process has been developed for preparing a Fischer-Tropsch catalyst precursor and a Fischer-Tropsch catalyst made from the precursor. The process includes contacting a gamma alumina catalyst support material with a first solution containing a vanadium compound and a phosphorus compound, to obtain a modified catalyst support material. The modified catalyst support material is calcined at a temperature of at least 500° C. The calcined modified catalyst support has a pore volume of at least 0.4 cc/g. The modified catalyst support is less soluble in acid solutions than an equivalent unmodified catalyst support. The modified catalyst support loses no more than 6% of its pore volume when exposed to water vapor. The modified catalyst support is contacted with a second solution which includes a precursor compound of an active cobalt catalyst component to obtain a catalyst precursor. The catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer-Tropsch catalyst.

  • Patent number: 9029018
    Abstract: A method for making a lithium battery cathode material is disclosed. A mixed solution including a solvent, an iron salt material, a vanadium source material and a phosphate material is provided. An alkaline solution is added in the mixed solution to make the mixed solution have a pH value ranging from about 1.5 to 5. The iron salt, the vanadium source material and the phosphate material react with each other to form a plurality particles of iron phosphate precursor doped with vanadium which are added in a mixture of a lithium source solution and a reducing agent to form a slurry of lithium iron phosphate precursor doped with vanadium. The slurry of lithium iron phosphate precursor doped with vanadium is heat-treated.

  • Publication number: 20150111126
    Abstract: The high current density performance of solid polymer electrolyte fuel cells using certain alloy catalyst compositions can be improved via appropriate treatment of the catalyst composition with a fluoro-phosphonic acid compound. In particular, fuel cells employing carbon supported Pt—Co cathode catalyst compositions with relatively high Co content benefit by treating the catalyst composition with 2-(perfluorohexyl) ethyl phosphonic acid.

  • Patent number: 9012349
    Abstract: A method for synthesizing catalyst beads of bulk transmission metal carbides, nitrides and phosphides is provided. The method includes providing an aqueous suspension of transition metal oxide particles in a gel forming base, dropping the suspension into an aqueous solution to form a gel bead matrix, heating the bead to remove the binder, and carburizing, nitriding or phosphiding the bead to form a transition metal carbide, nitride, or phosphide catalyst bead. The method can be tuned for control of porosity, mechanical strength, and dopant content of the beads. The produced catalyst beads are catalytically active, mechanically robust, and suitable for packed-bed reactor applications. The produced catalyst beads are suitable for biomass conversion, petrochemistry, petroleum refining, electrocatalysis, and other applications.

  • Patent number: 8962905
    Abstract: Process for the continuous hydrogenation of triglyceride containing raw materials in a fixed bed reactor system having several catalyst beds arranged in series and comprising at least one hydrogenation catalyst comprising an active phase constituted by a nickel and molybdenum element. The raw material feed, hydrogen containing gas and diluting agent are passed together through the catalyst beds at hydrogenation conditions. The raw material feed stream as well as the stream of hydrogen containing gas are divided into an equal number of different partial streams. These are each passed to one catalyst bed in such a manner that the weight ratio of diluting agent to raw material feed is essentially the same at the entrance of all catalyst beds and does not exceed 4:1. The claimed process is preferably conducted at low temperatures and allows the utilization of existing units due to the low recycle ratio.
