Title: Innovations of Toru Saito in Hydrorefining Technology

Introduction

Toru Saito is a prominent inventor based in Toda, Japan, known for his significant contributions to hydrorefining technology. With a total of five patents to his name, Saito has developed innovative methods that enhance the efficiency of catalyst regeneration and metal recovery processes.

Latest Patents

Saito's latest patents include a method for manufacturing a hydrorefining catalyst and a metal recovery method. The first patent describes a process where a heavy oil is hydrorefined using a hydrorefining catalyst. A spent hydrorefining catalyst, whose activity has decreased, is heat treated and pulverized to obtain a regenerated powder. This regenerated powder is then fractionated based on its metal content, formed, dried, and calcined to manufacture a regenerated catalyst. This catalyst exhibits a specific pore volume characteristic, allowing for efficient hydrodemetalization of heavy oil containing vanadium and nickel. The second patent outlines a method for preparing a hydrogenation purification catalyst, which features a bimodal pore characteristic, produced at low cost through the conversion of pseudo-boehmite into γ-alumina.
