Patent number: 8097555Abstract: Process for the production of hybrid catalysts formed by mixing two catalysts; one active in Fischer-Tropsch synthesis, the other being bifunctional. Such hybrid catalyst thus formed is active both in hydrocracking and in hydroisomerization reactions. The present invention in addition provides obtainment of a hybrid catalyst and application thereof conjointly with FT catalysts in Fischer-Tropsch synthesis reactions. The hybrid catalyst of the present invention is capable of producing in conditions typically such as those utilized in Fischer-Tropsch synthesis branched hydrocarbons in diverse bands relating to the products thereof (for example naphtha and diesel), reducing or even eliminating necessity for a subsequent hydrotreatment stage in such synthesis reactions.Type: GrantFiled: October 29, 2008Date of Patent: January 17, 2012Assignee: Petroleo Brasileiro S.A. - PetrobrasInventors: Alexandre de Figueiredo Costa, Agustin Martines Feliu, Joan Rollán Martinez, Henrique Soares Cerqueira, Joberto Ferreira Dias Junior, Eduardo Falabella Sousa Aguiar

Patent number: 8097557Abstract: 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: August 8, 2006Date of Patent: January 17, 2012Assignee: SD Lizenverwertungsgesellschaft mbH & Co. KGInventors: Vijay S. Bhise, Arie Bortinger, Stephen R. Allen

Publication number: 20120004093Abstract: A catalyst is provided, where the catalyst has an active surface that includes at least one nodular-structured (particulate) catalyst layer disposed on a support substrate, where the nodular-structured catalyst layer partially coats a surface of the support substrate. The invention further includes a fabrication method of the catalyst. The method includes depositing a catalyst precursor coating on a support substrate by heating a catalyst precursor solution on the support substrate, and further heating the catalyst precursor-coated substrate until a nodular-structured (particulate) catalyst is formed, where the nodular-structured catalyst layer partially coats a surface of the support substrate.Type: ApplicationFiled: March 3, 2009Publication date: January 5, 2012Applicant: THE STATE OF OREGON ACTING BY AND THROUGH THE STATInventors: Brian P.
