Title: Sakae Kawagoshi: Innovator in Catalytic Technology
Introduction
Sakae Kawagoshi is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of catalytic technology, particularly in the treatment of exhaust gases. With a total of 4 patents to his name, Kawagoshi's work has had a substantial impact on environmental engineering.
Latest Patents
Kawagoshi's latest patents include a catalyst for the oxidation of carbon monoxide and hydrocarbons in combustion. This innovative catalyst consists primarily of a carrier of active alumina, with at least one catalytic metal selected from platinum (Pt), palladium (Pd), rhodium (Rh), and iridium (Ir). The catalyst is produced by impregnating the carrier with an aqueous solution of thermally decomposable catalytic metal salts and baking the impregnated carrier in 100% steam at temperatures between 300°C and 600°C. The total amount of catalytic metals in the catalyst ranges from 0.03% to 0.3% by weight, with Rh and Ir limited to 0-0.03% by weight. This catalyst is noted for its high conversion ability for hydrocarbons, good durability, and low activity in converting sulfur dioxide (SO₂) to sulfur trioxide (SO₃), especially when using a combination of Pt and/or Pd with either Rh or Ir as the catalytic metals.
Another significant patent involves a method of preparing a catalyst for the treatment of exhaust gases. In this process, a carrier is first impregnated with a solution of a catalytically active metal compound and a sulfur compound. The impregnated carrier is then treated in a stream of high-temperature steam, enhancing its catalytic properties.
