摘要： Provided are titanium oxide fine particles which are excellent in transparency and are less photocatalytically active while maintaining a high refractive index, a dispersion of such fine particles, and a method for producing such a dispersion. The method for producing a dispersion of iron-containing rutile titanium oxide fine particles including a step (1) of neutralizing an aqueous metal mineral acid salt solution containing Ti and Fe in Fe2O3/(TiO2+Fe2O3)=0.001 to 0.010 to form an iron-containing hydrous titanic acid; a step (2) of adding an aqueous hydrogen peroxide solution to form an aqueous solution of iron-containing peroxotitanic acid having an average particle size of 15 to 50 nm; a step (3) of adding a tin compound so as to satisfy TiO2/SnO2=6 to 16; a step (4) of adding a sol of silica-based fine particles which contain Si and a metal element M in SiO2/MOx/2=99.9/0.1 to 80/20, the addition being made so as to satisfy SiO2/(oxides of the other elements)=0.08 to 0.22; and a step (5) of hydrothermally treating the solution obtained in the step (4).

摘要： There is provided a production method of a chain silica particle dispersion. This production method includes a dispersion preparation step of hydrolyzing alkoxysilane in the presence of ammonia to prepare a silica particle dispersion, an ammonia removal step of removing the ammonia from the silica particle dispersion such that an ammonia amount relative to silica contained in the silica particle dispersion is 0.3% by mass or less, and a hydrothermal treatment step of hydrothermally treating the silica particle dispersion having a silica concentration of 12% by mass or more, from which the ammonia has been removed, at a temperature of not lower than 150° C. and lower than 250° C. An abrasive including such chain silica particles is high in polishing rate and excellent in polishing properties.

摘要： 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.
