摘要： The present invention in a broad form relates to a process for oxidation of a gas comprising at least 0.05 vol% hydrogen sulfide and at least 0.05 vol% of the sum of carbon monoxide, carbonyl sulfide and carbon disulfide, comprising the steps of
(a) directing said gas to contact, at a first temperature, a first material catalytically active in oxidation of hydrogen sulfide at said first temperature, providing a heated and partially oxidized gas, and
(b) directing said partially oxidized gas to contact, at a second higher temperature, a second material catalytically active in oxidation of carbon monoxide, carbon disulfide and/or carbonyl sulfide providing an incinerated gas characterized in said first material being catalytically active in the oxidation of hydrogen sulfide at said first temperature, said second material being catalytically inactive in the oxidation of carbon monoxide and/or carbonyl sulfide at said first temperature and said second material being catalytically active in the oxidation of carbon monoxide and/or carbonyl sulfide at said second temperature with the associated benefit of reducing the requirements for inlet temperature as well as reducing the catalyst cost by reducing the required volume of expensive material catalytically active in oxidation of carbon monoxide and carbonyl sulfide, typically comprising noble metal.
