Title: Haruo Yoshioka: Innovator in Nitrogen Adsorption Technologies
Introduction
Haruo Yoshioka is a notable inventor based in Sakai, Japan. He has made significant contributions to the field of nitrogen adsorption technologies, holding 2 patents that showcase his innovative approaches to air separation methods.
Latest Patents
Yoshioka's latest patents include a selective adsorbent for nitrogen and a method for separating air using this adsorbent. The nitrogen selective adsorbent comprises a zeolite of a faujasite crystalline structure containing lithium and at least one of sodium and hydrogen as essential cations. This adsorbent exhibits a nitrogen adsorption characteristic represented by a specific correlation between the number of associated lithium ions per unit lattice of a zeolite crystal and the amount of adsorbed nitrogen per unit lattice of the zeolite crystal. The air separation method utilizes this nitrogen selective adsorbent to effectively separate nitrogen from oxygen through selective adsorption of nitrogen in air.
Another patent focuses on a nitrogen adsorbent that comprises a crystalline X zeolite with a faujasite structure, characterized by an SiO2/Al2O3 ratio of less than 3.0. This crystal contains at least one trivalent element from the group consisting of iron, boron, and gallium, along with aluminum tetrahedral units associated with cations. Despite the presence of a designated trivalent element, the adsorbent maintains the number of cation sites contributing to adsorption, demonstrating excellent separation performance of nitrogen and oxygen, as well as remarkable heat resistance. Notably, when this nitrogen adsorbent is heated under a vacuum before use, its adsorption performance is significantly enhanced.
