Title: The Innovations of Takanobu Watanabe: A Pioneer in NOx Reduction Technologies

Introduction

Takanobu Watanabe, an accomplished inventor based in Kyoto, Japan, has made significant contributions in the field of environmental technology with a focus on reducing nitrogen oxides (NOx) emissions. With five patents to his name, Watanabe's work demonstrates a commitment to advancing methods for improving air quality and minimizing the impact of pollution on public health.

Latest Patents

Watanabe's most notable inventions include:

1. **NOx adsorption and removal apparatus**: This innovative apparatus involves a method where NOx containing gas is directed into an adsorber filled with NOx adsorbent. The system allows specific volumes of NOx to be absorbed and later desorbed by passing hot air, effectively regenerating the adsorbent. The design features multiple zones arranged in parallel to enhance efficiency, reduce the size of the regenerating apparatus, and conserve energy by utilizing preheat effectively.

2. **Adsorbents for removing low-concentration nitrogen oxides**: This invention consists of four distinct adsorbents designed to capture low concentrations of nitrogen oxides without the adverse effects of moisture. The first adsorbent utilizes a gamma-alumina carrier with supported ruthenium. The second adsorbent features an anatase-type titania carrier with supported ruthenium. The third adsorbent includes a ceramic paper retaining an anatase-type titania carrier, also supporting ruthenium. Finally, the fourth adsorbent combines a ceramic paper retaining an anatase-type titania carrier, with co-supported ruthenium halide and an additional metal halide. These adsorbents highlight Watanabe's innovative approach to simplifying the dehumidification process typically required for such technologies.

Career Highlights

Throughout his career, Watanabe has worked at renowned organizations, including Hitachi Zosen Corporation and The Pollution-related Health Damage Compensation and Prevention.
