Abstract
A process for purifying gases from hydrogen sulphide which comprises oxidation of hydrogen sulphide with air oxygen at a volume ratio between hydrogen sulphide to oxygen equal to 1:1-1.5 on a catalyst having the following composition, % by weight: titanium dioxide--10-30, iron oxide--20-30, zinc oxide--20-25, chromium oxide--20-50. The process is conducted at a temperature within the range of from 220.degree. to 260.degree. C. and at a space velocity of the gas mixture of from 3,000 to 15,000 hr.sup.-1.
