Patent number: 11731114Abstract: A fluid catalytic cracking catalyst for hydrocarbon oil that is a blend of two types of fluid catalytic cracking catalysts each of which has a different hydrogen transfer reaction activity or has a pore distribution within a specific range after being pseudo-equilibrated. One catalyst is a catalyst containing a zeolite and matrix components, and the other catalyst is a catalyst containing a zeolite and matrix components. This catalyst is composed of the one catalyst and the other catalyst blended at a mass ratio within a range of 10:90 to 90:10.Type: GrantFiled: July 22, 2019Date of Patent: August 22, 2023Assignee: JGC CATALYSTS AND CHEMICALS LTD.Inventors: Takaki Mizuno, Chisuzu Tanaka, Tomohiro Mitsui

Patent number: 11566185Abstract: According to one or more embodiments described herein, a method for cracking a hydrocarbon oil may include contacting the hydrocarbon oil with a fluidized cracking catalyst including an ultra-stable Y-type zeolite in a fluidized catalytic cracking unit to produce light olefins, gasoline fuel, and coke. At least 99 wt. % of the hydrocarbon oil may have a boiling point greater than 350° C. The ultra-stable Y-type zeolite may be a framework-substituted zeolite in which a part of aluminum atoms constituting a zeolite framework thereof is substituted with 0.1-5 mass % zirconium atoms and 0.1-5 mass % titanium ions on an oxide basis. The fluidized cracking catalyst may include from 3.5 wt. % to 10 wt. % of one or more Group 7 metal oxides.Type: GrantFiled: May 26, 2022Date of Patent: January 31, 2023Assignees: Saudi Arabian Oil Company, JGC Catalysts and Chemical Ltd., Japan Cooperation Center PetroleumInventors: Omer Refa Koseoglu, Yaming Jin, Tatsuaki Hasegawa, Takaki Mizuno, Naoyuki Kido, Seiji Arakawa

Publication number: 20220023836Abstract: A production method comprises the steps of obtaining a mixed slurry by adding an alumina component and at least one selected from an alumina component and a clay mineral to a binder containing a silicon oxide; obtaining a metal trapping precursor by mixing the mixed slurry with a compound of a first metal component and heating the mixed slurry of metal component; and obtaining a metal trapping by drying and calcining the metal trapping precursor. A metal trapping comprises: a binder mainly containing silicon oxide, one or two selected from an alumina component and a clay mineral, and an oxide of a first metal component; having no peak of silicate of the first metal component detected in X-ray diffraction analysis, having an attrition resistance index CAI within a predetermined range. A fluid catalytic cracking catalyst comprises the metal trapping, a zeolite component, a binder component, and a clay mineral component.Type: ApplicationFiled: November 8, 2019Publication date: January 27, 2022Applicant: JGC CATALYSTS AND CHEMICALS LTD.Inventors: Mayumi Eto, Takaki Mizuno, Tomohiro Mitsui, Hiroshi Yamazaki, Hiroki Hasegawa

Patent number: 7901742Abstract: A method for forming a metal oxide fine particle layer, by which a metal oxide fine particle layer having uniformity and excellent in adhesion, abrasion resistance, strength, etc. can be formed easily compared with the conventional plating method, CVD method, liquid coating method, electrodeposition method or the like. The method comprises immersing a conductive substrate in a dispersion of metal oxide fine particles and fibrous fine particles and applying a direct-current voltage to the conductive substrate and the dispersion. The fibrous fine particles have a length (L) of 50 nm to 10 ?m, a diameter (D) of 10 nm to 2 ?m and an aspect ratio (L)/(D) of 5 to 1,000. The content of the fibrous fine particles in the dispersion is in the range of 0.1 to 20% by weight in terms of solids content, based on the metal oxide fine particles.Type: GrantFiled: June 18, 2007Date of Patent: March 8, 2011Assignee: JGC Catalysts and Chemicals Ltd.Inventors: Katsuhiro Shirono, Takaki Mizuno, Tsuguo Koyanagi
