Title: Kazuharu Ogasawara: Innovating Hydrogen Peroxide Production
Introduction
Kazuharu Ogasawara is a notable inventor based in Tokyo, Japan. With a strong focus on advancements in chemical processes, he has secured a total of four patents throughout his career. His work emphasizes the development of efficient methods in hydrogen peroxide production, showcasing his contributions to the field of industrial chemistry.
Latest Patents
Among his latest innovations, Ogasawara has developed a groundbreaking hydrogenation catalyst specifically designed for the production of hydrogen peroxide. This catalyst facilitates the hydrogenation of anthraquinones as part of an anthraquinone method of hydrogen peroxide production. The catalyst is composed of palladium supported on a silica carrier made up of spherical silica particles. Notably, at least 90 weight percent of these silica particles have diameters ranging from 10 to 100 micrometers, with an average diameter between 30 to 60 micrometers and a pore volume of 0.4 to 1.0 ml/g. These parameters contribute to the catalyst's desirable activity, strength, service life, and selectivity.
In addition to the catalyst, Ogasawara has also patented a method for preparing hydrogen peroxide using the same anthraquinone method. This method incorporates hydrogenating at least one anthraquinone with his specially designed catalyst, which includes palladium and a specific amount of at least one alkali metal supported on a silica carrier. The alkali metal concentration ranges from 0.1% to 5 weight percent based on the weight of the silica carrier.
