Latest Patents

Yamada holds a patent for a catalyst designed for producing ethylene oxide from ethylene. This catalyst comprises silver (Ag), cesium (Cs), rhenium (Re), and a carrier. The invention focuses on improving selectivity in the production process. The catalyst is produced by pretreating the carrier to support an alkali metal and then supporting Ag, Cs, and Re on the carrier. The specific surface area of the carrier ranges from 0.6 to 3.0 m/g, with a weight ratio of silicon (Si) to sodium (Na) content of 2 to 50 in terms of SiO/NaO. The catalyst contains Re in a concentration of 170 to 600 ppm per 1 m/g of the specific surface area of the carrier, and the molar ratio of Cs to Re is maintained between 0.3 to 19.
