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

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.
