With a total of 2 patents to his name, Yamaoka's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
Yamaoka's latest patent focuses on a method of producing dimethyl ether from a mixed gas containing carbon monoxide and either hydrogen or water vapor. This method involves using a mixed catalyst that is prepared by pulverizing a combination of zinc oxide, copper oxide, or chromium oxide, along with aluminum oxide. The process includes compressing these materials under high pressure and then pulverizing them again. This innovative approach results in a high yield of dimethyl ether and a significant conversion of water produced through the reaction to hydrogen. Additionally, the method is designed to avoid clogging issues with the catalyst and does not require high mechanical strength. The applicable range of the carbon monoxide to hydrogen ratio is broad, allowing for reactions in the presence of high concentrations of carbon dioxide, while also minimizing the effects of impurities and catalyst poisons.
