Title: Shigeo Yaguchi: Innovator in Coal Reforming Technology

Introduction

Shigeo Yaguchi is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of coal reforming technology. His innovative methods aim to enhance the efficiency of low-grade coal utilization.

Latest Patents

Yaguchi holds a patent for a method for reforming low-grade coals. This method involves mixing steam coal, such as sub-bituminous coal and brown coal, with a catalyst, a co-catalyst (sulfur), and hydrocarbonaceous heavy oil. The mixture is then thermally reformed in a reducing gaseous atmosphere at elevated pressure and temperature, specifically between 400°C to 450°C. The resultant reaction mixture is distilled at a reduced pressure of 40-150 mm Hg and at a temperature of 280°C to 350°C. An iron type catalyst is utilized in proportions up to 3 wt.% based on the coal, and both sulfur and heavy oil are recycled. Yaguchi's innovative approach has led to the development of a process that is crucial for producing metallurgical coke from low-grade coal. He has 1 patent to his name.
