Title: Fumisada Kosuge: Innovator in Chemical Engineering
Introduction
Fumisada Kosuge is a prominent inventor based in Niigata, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production and purification of nitrile compounds. With a total of 5 patents to his name, Kosuge's work has had a substantial impact on industrial processes.
Latest Patents
One of his latest patents is a reactor for producing a nitrile compound and a method for operating the reactor. This innovative reactor utilizes a gas phase reaction with ammonia and a gas containing oxygen to produce nitrile compounds from carbon rings or heterocyclic compounds. The design features a cylindrical fluidized catalyst bed with a diameter of 2.0 meters or greater, incorporating both partial vaporization-type and complete vaporization-type cooling tubes. This arrangement allows for stable temperature control and continuous operation in commercial-scale applications.
Another notable patent is a method of purifying isophthalonitrile. This method involves separating isophthalonitrile from a gas produced by the reaction of m-xylene with ammonia and oxygen in the presence of a catalyst. By using an organic solvent with a lower boiling point than isophthalonitrile, the process effectively recovers high-purity isophthalonitrile while preventing losses and system blockages.
