Title: Tetsuhiko Matsuura and High-Purity Nitrogen Separation

Introduction

Tetsuhiko Matsuura is an inventor associated with Bizen, Japan, and Kuraray Chemical Co., Ltd. His patent work focuses on pressure-swing adsorption processes for separating high-purity nitrogen from gas mixtures.

Latest Patents

Matsuura is credited with 2 patents concerning nitrogen separation.

“Process for separating nitrogen gas” describes a pressure-swing adsorption method that transfers gas between adsorbers at different stages of the adsorption cycle. The process discharges part of the transferred gas from the system and is designed to produce nitrogen with a purity of at least 99.99% using compact equipment.

“Process for separating nitrogen gas by pressure swing adsorption system” describes a method using a carbon molecular sieve. It controls gas transfer between adsorbers, stops the transfer before pressure equalization, and promotes regeneration by directing some product gas backward. The patent presents an economical approach to producing 99.99%-pure nitrogen from air.

Career Highlights

Matsuura’s listed inventions address a technical challenge in pressure-swing adsorption: achieving very high nitrogen purity while maintaining an economical process. Both patents emphasize carefully managed gas transfer and adsorber regeneration.

Collaborations

Matsuura’s work is associated with Kuraray Chemical Co., Ltd. His listed coworkers include Takeshi Tamaru and Tsuneo Gemba.

Conclusion

Tetsuhiko Matsuura’s patent contributions center on pressure-swing adsorption techniques designed to produce high-purity nitrogen efficiently from air.
