The process in order to be oxidized sulphur directly by catalysis, with a high selectivity, the h2s present in low concentration in a gas and catalyst for óoeuvre of this process.

摘要

The gas containing the h2 s with a gas containing oxygen, in an amount which is adapted to provide a molar ratio of o2: h2 s ranging from 0,5 to 3, and preferably from 0,5 to 1,5, in contact with an oxidation catalyst, the h2 s, by carrying out said contact at temperatures below 200degré c. the catalyst consists of a support in the activated carbon which is incorporated a catalytic phase is chosen from among the compounds of the oxides or sulphides of one or several transition metals selected from v, mo, w, ni and co, the quantity of the catalytic phase, expressed by weight of transition metal, representing 0,1% to 15% of the weight of the calcined catalyst.
