Title: Innovations of Toshikazu Yoshikawa

Introduction

Toshikazu Yoshikawa is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of catalyst recycling, particularly in denitration processes. With a total of 3 patents, his work focuses on enhancing the efficiency of catalysts used in environmental applications.

Latest Patents

Yoshikawa's latest patents include innovative methods for recycling denitration catalysts. One method involves spraying an aqueous solution with a pH of 7 or more onto a used denitration catalyst while it is set in a denitration device. This process effectively removes the surface of the catalyst, which contains 43 wt % or more of vanadium pentoxide and has a BET specific surface area of 30 m/g or more. The recycled catalyst can then be utilized for denitration at temperatures of 200°C or lower. Another method he developed includes removing a used denitration catalyst from a denitration device and coating it with a catalyst component that also contains a high percentage of vanadium pentoxide.

Career Highlights

Throughout his career, Yoshikawa has worked with prominent organizations such as Chugoku Electric Power Co., Inc. and Tokyo Metropolitan University. His experience in these institutions has allowed him to advance his research and contribute to the development of innovative solutions in catalyst technology.

Collaborations
