  • Cold process for removal of sulfur in straight run diesel by ozone and tert-butyl hydroperoxide
    Patent number: 9365780
    Abstract: A method and process to remove sulfur compounds from a real fuel product of straight-run diesel (SRD) by the action of ozone bubbling and tert-butyl hydroperoxide (t-BUOOH) under normal laboratory conditions is disclosed. Slight desulfurization is taken place after ozone bubbling process which may be assigned to a removal of sulfur compounds in a gaseous form (SOx). Most of the organically bound sulfur and/or elemental sulfur and hydrogen sulfide still exist in the ozonized samples. Sulfur removal from SRD samples was achieved by combining ozone bubbling with extraction by using different solvents to remove the oxidized sulfur compound (polar) from ozonized samples. This method provides a considerable level of total sulfur reduction where the reduction of sulfur reaches 93%.

  • Catalytic composition for the electrochemical reduction of carbon dioxide
    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.

  • Method for preparation of epoxy-clay nanocomposites
    Patent number: 9334387
    Abstract: The method for the preparation of epoxy-clay nanocomposites uses high shear mixing of Nanomer I.30 E nanoclay into the diglycidyl ether of bisphenol A (DGEBA) epoxy by optimization of high shear mixing speeds, mixing times and degassing temperature. The results showed that the optimum high shear mixing speed and mixing time for optimal clay dispersion were 6000 rpm and 60 min, respectively. Increasing the degassing temperature from 65° C. to 100° C. for the first two hours of the degassing process enhanced nanoclay dispersion, resulting in nanocomposites with a morphology dominated by disorder intercalation with some exfoliated structure. This enhancement in nanocomposite morphology can be attributed to the improvement in epoxy diffusion into the intergallery spacing between clay layers due to temperature rise.
