  • Patent number: 8383543
    Abstract: The invention relates to a bulk multi-metallic catalyst for hydrotreating heavy oil feeds and to a method for preparing the catalyst. The bulk multi-metallic catalyst is prepared by sulfiding a catalyst precursor having a poorly crystalline structure with disordered stacking layers, with a type IV adsorption-desorption isotherms of nitrogen with a hysteresis starting point value of about 0.35, for a sulfided catalyst that will facilitate the reactant's and product's diffusion in catalytic applications. In another embodiment, the precursor is characterized as having a type H3 hysteresis loop. In a third embodiment, the hysteresis loop is characterized as having a well developed plateau above P/Po of about 0.55. The mesapores of the precursor can be adjustable or tunable.

    Abstract: A metal fiber based on one or several elements from the group of platinum, palladium, rhodium, ruthenium, and iridium with 0 to 30% by weight of one or several additional alloy elements from the group of nickel, cobalt, gold, rhenium, molybdenum, and tungsten, contains 1 to 500 ppm by weight of boron or phosphorus. A non-woven material or netting, in particular for the production of nitrogen oxide or for the production of hydrocyanic acid, is made of such fibers. For the production of fibers based on noble metals having up to 30% by weight of additional alloy metals by drawing the fibers from a melt, the melting point of the metal is reduced by at least 400° C., before drawing of the fibers, by additionally alloying with boron or phosphorus, and the boron or the phosphorus is removed again from the fibers.

  • Patent number: 8354049
    Abstract: An antibacterial measure using titanium oxide includes mixing titanium oxide in a resin to form a coating resin, and then coating a key surface with the coating resin. This method requires formation of a coating layer on a resin molding and thus increases the number of the production steps and cost. Furthermore, in the method, a coating film containing an antibacterial agent is scraped off light by little at each time of keying, and thus the film is finally completely removed to lose its antibacterial function. A conceivable measure against this includes directly mixing a resin and an antibacterial agent. However, titanium oxide used as an antibacterial agent degrades a raw material resin. It has recently be thought that photocatalytic apatite as a substitute for titanium oxide also causes chalking, and an antibacterial coating layer has been formed on a surface of a resin molding.

    Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.
