Title: Hiroshi Yoshimura: Innovator in Coal Liquefaction Technologies
Introduction
Hiroshi Yoshimura is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of coal liquefaction, holding 2 patents that focus on innovative methods for enhancing the efficiency of this process. His work has implications for energy production and environmental sustainability.
Latest Patents
Yoshimura's latest patents include a "Method of Coil Liquefaction by Hydrogenation" and a "Method of Treating Brown Coal for Liquefaction." The first patent describes a method for hydro-liquefying coal, which involves preheating a slurried mixture of pulverized coal and a solvent. This mixture is then supplied to multiple reactors, where gaseous content is separated from the reaction products. The process includes dehydrating the gaseous content and removing light oil, resulting in hydrogen-content gases that are recycled back to the first reactor. The second patent outlines a process where a slurry of raw brown coal and solvent is heated and pressurized, followed by gas-liquid separation and hydrogenation. This method improves liquefaction efficiency by converting carbonate-forming metal components in brown coal into carbonates.
Career Highlights
Throughout his career, Yoshimura has worked with prominent companies such as Kobe Steel, Ltd. and Mitsubishi Chemical Corporation. His experience in these organizations has allowed him to develop and refine his innovative approaches to coal liquefaction.
Collaborations
