Title: Innovations by Yoshifumi Kameoka

Introduction

Yoshifumi Kameoka is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of materials processing, particularly in the production of reduced iron and light oil from iron ore and heavy oil. His innovative methods have garnered attention in the industry, leading to the filing of multiple patents.

Latest Patents

Kameoka holds 2 patents that focus on advanced processes for producing reduced iron and light oil. His first patent describes a method of producing reduced iron and light oil from iron ore and heavy oil. This method involves a thermal cracking step that subjects heavy oil to thermal cracking while retaining iron ore particles in a fluidized state. This process produces light oil and deposits coke as a by-product on the surface of the iron ore particles. The subsequent gasification step involves contacting the coke-deposited ore with an oxidizing gas, including steam and oxygen, to produce a reducing gas containing hydrogen and carbon monoxide. The final reduction step reduces the coke-deposited iron ore using the reducing gas to yield reduced iron.

His second patent outlines a novel process for concurrently producing reduced iron and thermally cracking heavy oils. In this process, the thermal cracking reaction is performed in a fluidized state with fine iron ore as the medium. The carbonaceous by-product material coats the iron ore particles, which are then introduced into a fluidized-bed reducing furnace. Here, the iron ore is reduced into reduced iron by contacting it with a reducing gas produced from the cracked gas or residual oil.
