Title: Innovations of Yoshiyuki Hayashi
Introduction
Yoshiyuki Hayashi is a notable inventor based in Tokoname, Japan. He has made significant contributions to the field of exhaust gas purification technology. With a total of three patents to his name, his work focuses on improving the efficiency of lean burn engines and reducing harmful emissions.
Latest Patents
One of his latest patents is an exhaust gas purification catalyst for lean burn engines. This invention aims to provide a catalyst that has sufficient NOx purification performance. The catalyst component includes noble metal and ceria supported on a three-dimensional structure. The supported amount of ceria per liter of catalyst ranges from 140 to 300 g/L, making up 50 to 98% by mass of the whole coated amount. Notably, 50% by mass or more of ceria is included in the same catalyst layer as the noble metal, with the noble metal amount being at least 0.1% by mass relative to the ceria.
Another significant patent is the NOx storage reduction catalyst for purifying exhaust gas. This catalyst efficiently removes harmful components such as carbon monoxide, hydrocarbons, and nitrogen oxides from exhaust gas. It utilizes a complex oxide of strontium and cerium as a catalytic active component. This complex oxide is characterized by its ability to adsorb 1.0 mL or less of oxygen per gram in a 400°C atmosphere, and it sinters a precursor at temperatures of 300°C or more.
