process for the catalytic incineration of waste gases containing low concentration, at least in a compound of sulphur chose between cos.cs2 and mercaptans and, where appropriate, at least one member selected from the group consisting of h2s, so2, sulfur steam and / or vesicular.

摘要

Process for the incineration of wastewater gas containing, in low concentration, hs and or so, the organic compounds of sulphur, such as cos, cs, mercaptans, and optionally of the sulphur vapour and or vesicular, comprising a step of transforming the hydrogenation of hs all the compounds sulfurs followed by a step of catalytic oxidation in order to convert hs. / p & & p & the catalyst of the step of oxidation consists of a porous support, at least the same specific surface area is 5mg and containing, by weight, 50 to 100 of a product chosen from among oxides of titanium or zirconium oxide, silica, zeolites, and 50 to 0 of alumina, which has been associated with one or more compounds of metals belonging to the group consisting of cu, ag, zn, cd, y, lanthanides, v, cr, mo, w, mn, fe, co, rh, ir, ni, pd, pt, sn and bi. / p & & p & the use of such an oxidation catalyst leads to a substantially quantitative yield of conversion of the hs in, this efficiency is now a long-lasting.
