Sulfur and hydrogen are produced from hydrogen sulfide by bringing hydrogen sulfide into contact, at a temperature exceeding the boiling point of sulfur, with at least one member selected from the group consisting of the sulfides of molybdenum, tungsten and ruthenium to give rise to a gaseous mixture consisting of hydrogen sulfide, hydrogen and sulfur. The produced mixture is cooled to separate therefrom the sulfur component in the condensed form and leave behind a gaseous mixture whereas the hydrogen component makes up the majority of the total weight thereof. Hydrogen sulfide is removed from this mixture by means of condensation or absorption.
