Patent number: 11642664Abstract: Alumina support compositions comprising at least 0.1 wt % of silica are disclosed. The alumina support are characterized by a pore volume of greater than 0.60 cc/g, a median pore size ranging from about 70 to about 120, a pore size distribution such that at least 90% of the total pore volume falls within the range of about 20 to about 250, and a pore size distribution width of no less than about 40. Alumina compositions of the present invention exhibit a primary peak mode at a pore diameter less than the median pore diameter. Also provided are catalysts made from the alumina supports, and processes of preparing and using the supports and catalysts.Type: GrantFiled: August 3, 2021Date of Patent: May 9, 2023Assignee: Advanced Refining Technologies LLCInventors: Xianghua Yu, Bruno Nesci, Roberto Romero, Gill M. Malick, Jifei Jia, Cecelia A. Radlowski

Patent number: 10376873Abstract: This disclosure relates to supported multi-metallic catalysts for use in the hydrotreating of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor comprised of at least one Group VIB metal, at least one Group VIII metal and an organic acid. The catalyst precursor is thermally treated to partially decompose the organic acid, then sulfided. The catalysts have a high carbon-as-carboxyl to total carbon ratio (Ccarboxy/Ctotal) as a result of a unique post-metal calcination method employed during the manufacture of the catalyst.Type: GrantFiled: April 24, 2014Date of Patent: August 13, 2019Assignee: Advanced Refining Technologies LLCInventors: Xianghua Yu, Shuguang Zhang, Gill M. Malick, Bruno Nesci, Henry Saternus, Jifei Jia, Cecelia Radlowski, Theodorus Ludovicus Michael Maesen, Colleen T. Miedona

The catalysts are prepared from a catalyst precursor comprised of at least one Group VIB metal, at least one Group VIII metal and an organic acid.

The catalysts have a high carbon-as-carboxyl to total carbon ratio (Ccarboxy/Ctotal) as a result of a unique post-metal calcination method employed during the manufacture of the catalyst. As a result, the hydrotreating catalysts have lower percent weight loss-on-ignition, higher activity and longer catalyst life.Type: GrantFiled: April 24, 2014Date of Patent: August 6, 2019Assignee: Advanced Refining Technologies LLCInventors: Xianghua Yu, Shuguang Zhang, Gill M.
