Title: Maki Hamaguchi: Innovator in Ashless Coal Production

Introduction

Maki Hamaguchi is a prominent inventor based in Kobe, Japan. She has made significant contributions to the field of coal production, particularly in developing methods that minimize ash content in coal. With a total of 13 patents to her name, her work is recognized for its innovative approach to environmental sustainability.

Latest Patents

Hamaguchi's latest patents include an "Ashless-coal production device" and an "Ashless-coal production method." The production apparatus of ashless coal consists of several components, including a preheater, an extraction tank, a feed pipe, a solid-liquid separator, and a solvent separator. The preheater is responsible for heating a solvent, while the extraction tank extracts coal components soluble in the solvent from a slurry mixture. The coal feeding unit ensures that the solvent does not flow back during the feeding process. The solid-liquid separator effectively separates the solution containing the coal component from the slurry, and the solvent separator evaporates and separates the solvent to yield ashless coal.

Additionally, her carbon material production method involves an oxidation step that oxidizes ashless coal, followed by a forming step that mixes oxidized and unoxidized ashless coal. The final carbonization step carbonizes the formed body, resulting in a high-quality carbon material.
