Title: **Kiyoshige Hayashi: Pioneering Innovations in Carbon Materials**

Introduction

Kiyoshige Hayashi, a prominent inventor based in Tokyo, Japan, has made significant contributions to the field of carbon materials and petroleum processing. With a remarkable portfolio consisting of six patents, Hayashi's work exemplifies innovation and a dedication to enhancing the purity and quality of carbon products.

Latest Patents

One of Hayashi's notable patents is the "Process for the production of a petroleum pitch or coke of a high purity". This method involves treating petroleum heavy residues, such as distillation and cracked residua, asphalt, and pitch, with hydrogen under specific conditions to yield a petroleum pitch or coke of extra high purity. The process utilizes a non-catalytic hydrogen treatment termed 'hydrogenation refining', which enhances the quality of the feedstock for traditional pitching or coking.

Another key patent is the "Production of high-density carbon materials". In this innovative process, Hayashi describes a method for creating high-density carbon from green coke without the use of binders. By incorporating a small amount of water or a certain monohydric alcohol during the molding process, he successfully overcomes the problem of laminar cracks, ensuring a more durable sintered carbon material.
