Latest Patents
Yukio Ito's latest patents include a pentasil-type zeolite and a method for manufacturing the same. The purpose of this invention is to provide a pentasil-type zeolite that combines a higher BET specific surface area and a higher acid amount than previously achieved. The zeolite is characterized by a BET specific surface area of 450 m²/g or more, and an acid amount of 0.38 mmol/g or more, measured by the ammonia-TPD method. This innovative zeolite can be produced through a crystallization process involving a mixture of tetrabutylphosphonium cations, silica, alumina, an alkali metal source, and water, with a specific molar ratio of alkali metal to silica.
Another notable patent is for a highly heat-resistant β-type zeolite and an SCR catalyst employing the same. This invention aims to provide a catalyst with an NOx reduction percentage of 40% or higher at 200°C after hydrothermal durability treatment. The β-type zeolite has an SiO/AlO molar ratio of 20 or higher but less than 30, and a crystallite diameter of 20 nm or larger before treatment. The zeolite demonstrates minimal change in crystallite size after treatment and has a fluorine content lower than 0.1%.
