Latest Patents

One of Naoyuki Todo's latest patents involves a process for the production of hydrogen and sulfur from hydrogen sulfide. This process entails bringing hydrogen sulfide into contact, at a temperature exceeding the boiling point of sulfur, with sulfides of molybdenum, tungsten, and ruthenium. The result is a gaseous mixture that includes hydrogen sulfide, hydrogen, and sulfur. The mixture is then cooled to separate the sulfur component in condensed form, leaving behind a gaseous mixture where hydrogen constitutes the majority of the total weight. Subsequently, hydrogen sulfide is removed from this mixture through condensation or absorption.
