  Verfahren zur Reduktion von Sulfaten mittels reduzierender Gase. 



   Das Stammpatent Nr. 90258 behaudelt die Reduktion von Sulfaten zu Sulfiden mit Hilfe von Kohlenwasserstoffen bei   8600 bis 10600 C.   



   Es ist   nun     erkannt worden, dass ausser Kohlenwasserstoffen auch noch   andere reduzierende Gase, z. B.   Kohlenoxyd, fnr sich   allein oder auch in Mischung mit Wasserstoff oder Kohlenwasserstoffen, die Reduktion innerhalb des angegebenen Temperaturgebietes durchzufübren vermögen. 



   Die Erweiterung gegenüber dem Stammpatent liegt darin, dass   zur Reduktion   der Sulfate 
 EMI1.1 
 dadurch gekennzeichnet, dass   der'Reduktionsprozess   bei   einer Temp ? ratur durchgeführt wird. die praktisch   zwischen   850  und 1050  Ht'gt.   

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the reduction of sulphates by means of reducing gases.



   The parent patent No. 90258 claims the reduction of sulfates to sulfides with the help of hydrocarbons at 8600 to 10600 C.



   It has now been recognized that in addition to hydrocarbons, other reducing gases, e.g. B. carbon oxide, alone or in a mixture with hydrogen or hydrocarbons, are able to carry out the reduction within the specified temperature range.



   The extension compared to the parent patent is that it reduces sulfates
 EMI1.1
 characterized in that the'Reduktionsprozess at a Temp? temperature is carried out. which practically between 850 and 1050 Ht'gt.
