Process for the removal of sulphur compounds from gases

   
   

The invention is directed to a process for the catalytic reduction of sulphur dioxide from a gas mixture at least containing 10 vol. % of water, in which process the gas mixture is passed over a sulphur resistant hydrogenation catalyst in sulphidic form, at a space velocity of at least 2000 h.sup.-1, in the presence of a reducing component, preferably at least partly consisting of hydrogen, in a molar ratio or reducing component to sulphur dioxide of more than 10 up to 100, at a temperature of 125.degree. C. to 300.degree. C., followed by passing the gas mixture, after the said reduction, through a dry oxidation bed for the oxidation of sulphur compounds, more in particular hydrogen sulphide, to elemental sulphur.

Вымысел направлен к процессу для каталитического уменьшения двуокиси сульфата от газовой смеси по крайней мере содержа 10 VOL % воды, в процесс которой газовая смесь пропущена над катализатором гидрогенизации серы упорным в sulphidic форме, на скорости космоса по крайней мере 2000 h.sup.-1, in the presence of уменьшение компонентное, предпочтительн по крайней мере отчасти consist of водопод, в молярном коэффициенте или компонент уменьшения к двуокиси сульфата больше чем 10 up to 100, на температуре 125.degree. C к 300.degree. C, последованное за путем проходить газовую смесь, после сказанного уменьшения, через сухую кровать оксидации для оксидации смесей серы, более в частности сульфида водорода, к elemental сере.
