A method for the catalytic incineration of residual gases, which, in low concentration of at least one of the sulfur compounds, cos cs (arrow down) 2 (arrow down), mercaptans and, if appropriate, at least one representative of the group consisting of h (arrow down) 2 (arrow down) s, so (arrow down) 2 (arrow down), and / or sulfur gas bubbles schwefeldaempfe contain

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.
