Patent number: 8389435Abstract: A metal oxide catalyst carrier particle has a center portion and an outer skin portion each containing a first metal oxide and a second metal oxide. The center portion and the outer skin portion are different in composition. The mole fraction of the metal of the first metal oxide is higher in the center portion than in the outer skin portion and the mole fraction of the metal of the second metal oxide is higher in the outer skin portion than in the center portion. The second metal oxide is selected from the group consisting of rare earth oxides, except for ceria, and alkali earth metal oxides. In addition, platinum is supported on the metal oxide catalyst carrier particle, thus forming an exhaust gas purification catalyst.Type: GrantFiled: March 30, 2007Date of Patent: March 5, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masahide Miura, Nobuyuki Takagi, Shinichi Matsumoto, Toshitaka Tanabe, Yasutaka Nagai, Kazuhiko Dohmae, Yasuo Ikeda

Patent number: 8378129Abstract: The invention relates to an improved process for producing a catalyst useful for the epoxidation of ethylene to ethylene oxide. In forming the catalyst, a silver-impregnated support is subjected to two calcinations. The support is subjected to a first calcination in a first atmosphere comprising air. Next the support is subjected to a second calcination in a second atmosphere which is substantially entirely comprised of inert gas, and which second atmosphere is substantially absent of hydrogen. This two-stage calcination produces an improved catalyst which contains fewer organics left over under standard conditions of air calcination alone, while costing less than calcination in an inert gas alone.Type: GrantFiled: October 25, 2011Date of Patent: February 19, 2013Assignee: SD Lizenzverwertungsgesellschaft mbH & Co. KGInventors: Vijay S. Bhise, Arie Bortinger, Stephen R. Allen

Patent number: RE44124Abstract: A regenerable, high-capacity sorbent for removal of mercury from flue gas and processes and systems for making and using the sorbent. A phyllosilicate substrate, for example vermiculite or montmorillinite, acts as an inexpensive support to a thin layer for a polyvalent metal sulfide, ensuring that more of the metal sulfide is engaged in the sorption process. The sorbent is prepared by ion exchange between the silicate substrate material and a solution containing one or more of a group of polyvalent metals including tin (both Sn(II) and Sn(IV)), iron (both Fe(II) and Fe(III)), titanium, manganese, zirconium and molybdenum, dissolved as salts, to produce an exchanged substrate. Controlled reaction of a sulfide ion source with the one or more polyvalent metals that are exchanged on the silicate substrate produces the sorbent. The sorbent is used to absorb elemental mercury or oxidized mercury species such as mercuric chloride from flue gas containing acid gases (e.g.Type: GrantFiled: October 29, 2009Date of Patent: April 2, 2013Assignee: Novinda, Inc.Inventors: John Lovell, Craig Turchi, Thomas E.
