  • Patent number: 9403155
    Abstract: The present invention concerns a novel additive composition for reducing sulfur content of a catalytically cracked gasoline fraction. This additive composition comprises a support consisting of porous clay into which a first metal from group IVB is incorporated and a second metal from group IIB is impregnated. Preferably, the first incorporated metal is zirconium and the second impregnated metal is zinc. The sulfur reduction additive is used in the form of a separate particle in combination with a conventional cracking catalyst in a fluidized catalytic cracking process to convert hydrocarbon feed stocks into gasoline having comparatively lower sulfur content and other liquid products.

  • Publication number: 20160184812
    Abstract: A catalyst system and a process for methanol to light olefin conversion with enhanced selectivity towards propylene. The catalyst system comprises a honeycomb monolith catalyst support coated with aluminosilicate nanozeolite catalysts on the edges and inside the channels of the support structure. The aluminosilicate nanozeolite catalysts have not been pre-modified with a promoter metal. The catalyst system gives higher hydrothermal stability to the catalyst compared to randomly packed pellet catalysts and allows methanol to be converted to predominantly propylene at a low temperature, with decreased selectivity towards C2, higher olefins and paraffinic hydrocarbons.

  • Patent number: 9333487
    Abstract: The catalytic composition for the electrochemical reduction of carbon dioxide is a metal oxide supported by multi-walled carbon nanotubes. The metal oxide may be nickel oxide (NiO) or tin dioxide (SnO2). The metal oxides form 20 wt % of the catalyst. In order to make the catalysts, a metal oxide precursor is first dissolved in deionized water to form a metal oxide precursor solution. The metal oxide precursor solution is then sonicated and the solution is impregnated in a support material composed of multi-walled carbon nanotubes to form a slurry. The slurry is then sonicated to form a homogeneous solid solution. Solids are removed from the homogeneous solid solution and dried in an oven for about 24 hours at a temperature of about 110° C. Drying is then followed by calcination in a tubular furnace under an argon atmosphere for about three hours at a temperature of 450° C.

  • Publication number: 20150285534
    Abstract: The solar collector with optimal profile for energy distribution on a tubular receiver collects and distributes solar energy. Solar energy received from the sun can be modified by either being re-directed (reflection) or being redistributed. In the present invention energy is reflected and redistributed in a manner that yields a required energy variation over a surface. The receiver is a cylinder of known length and diameter. Longitudinal distribution of energy is specified by a user defined function. Circumferential distribution is assumed to be constant. Energy distribution is required to vary along the z axis of the receiver but remain constant in the circumferential direction. An axi-symmetric approach is used in which only one plane of the receiver in r and Z plane is considered. A geometric solution determines a reflecting surface that gives a required energy distribution along the z-axis. A complete reflector is designed by expanding the axi-symmetric behavior.

  • Publication number: 20150238930
    Abstract: The metal organic framework adsorbent for solar adsorption refrigeration is a nanocomposite made from a metal organic framework matrix having carbon nanotubes incorporated therein. Preferably, the metal organic framework is composed of MIL-100(Fe), and the carbon nanotubes are functionalized with carboxyl (COOH) groups. In order to prepare the metal organic framework adsorbent, carbon nanotubes functionalized with carboxyl (COOH) groups are first added to an aqueous solution of a precursor salt, such as ferric trinitrate nonahydrate (Fe(NO3)3·9H2O), to form a first mixture. The first mixture is then sonicated and a 1,3,5 benzenetricarboxylic acid ligand is added thereto to form a second mixture. The second mixture is then sonicated and heated, and the metal organic framework nanocomposite is separated therefrom, preferably as a powder.

  • Patent number: 9109293
    Abstract: An electrocatalyst for the electrochemical conversion of carbon dioxide to hydrocarbons is provided. The electrocatalyst for the electrochemical conversion of carbon dioxide includes copper material supported on carbon nanotubes. The copper material may be pure copper, copper and ruthenium, copper and iron, or copper and palladium supported on the carbon nanotubes. The electrocatalyst is prepared by dissolving copper nitrate trihydrate in deionized water to form a salt solution. Carbon nanotubes are then added to the salt solution to form a suspension, which is then heated. A urea solution is added to the suspension to form the electrocatalyst in solution. The electrocatalyst is then removed from the solution. In addition to dissolving the copper nitrate trihydrate in the deionized water, either iron nitrate monohydrate, ruthenium chloride or palladium chloride may also be dissolved in the deionized water to form the salt solution.
