Description

Herstellung von Alkali- und Erdalkalisulfiden aus den entsprechenden Sulfaten Gegenstand des Patents 642 196 ist ein Verfahren zur Herstellung von Alkali- und Erdalkalisulfiden aus den entsprechenden Sulfaten durch Reduktion mit Wasserstoff oder anderen reduzierenden Gasen in fester Phase in Gegenwart von Schwermetallkatalysatoren, wobei man das Sulfat in Mischung mit Katalysatoren, die aus den Metallen oder Verbindungen der B. Gruppe, z. B. Eisen, und/oder denjenigen der i. Nebengruppe, z. B. Kupfer, des periodischen Systems, gemischt mit Molybdän, Wolfram, Uran, Titan, Thorium, Arsen, Antimon, Wismut oder Phosphor bzw. deren Verbindungen allein oder mit Mischungen dieser, bestehen, gegebenenfalls als Formlinge, der Reduktion unterwirft.Production of alkali and alkaline earth sulfides from the corresponding Sulphates The subject of patent 642 196 is a process for the production of alkali and alkaline earth sulfides from the corresponding sulfates by reduction with hydrogen or other reducing gases in the solid phase in the presence of heavy metal catalysts, taking the sulfate in mixture with catalysts derived from the metals or compounds the B. group, e.g. B. iron, and / or those of i. Subgroup, e.g. B. copper, of the periodic table mixed with molybdenum, tungsten, uranium, titanium, thorium, Arsenic, antimony, bismuth or phosphorus or their compounds alone or with mixtures these exist, possibly as moldings, subject to reduction.

Es wurde weiter gefunden, daß außer den genannten Elementen bzw. ihren Verbindungen auch das Zinn, Blei, Vanadin, Niob und Tantal sowie ihre Verbindungen, zumal wenn sie in Form von Oxyden oder Sulfiden eingebracht werden, sich als vorzügliche Aktivatoren für die Grundkatalysatoren erwiesen haben.It was also found that in addition to the elements mentioned or their Compounds also include tin, lead, vanadium, niobium and tantalum and their compounds, especially when they are introduced in the form of oxides or sulphides, they prove to be excellent Activators for the basic catalysts have proven.

Beispiel i i ooo kg Natriumsulfat, das von seiner Herstellung her o, 2 % Fe enthält, werden mit 2 kg Bleimennige innig vermischt, angefeuchtet und in bekannter Weise brikettiert. Die erhaltenen Formlinge werden erhitzt und alsdann mit Wasserstoff bei 6oo bis 6o5° reduziert. Nach 2- bis 3stündiger Reduktionszeit sind die Formlinge bis zu 95 bis 99°i6 reduziert.EXAMPLE II Ooo kg of sodium sulphate, which from its production contains 0.2% Fe, are intimately mixed with 2 kg of red lead, moistened and briquetted in a known manner. The briquettes obtained are heated and then reduced with hydrogen at 600 to 605 °. After a reduction time of 2 to 3 hours, the briquettes are reduced by up to 95 to 99 ° i6.

Beispiel 2 ioookg Natriumsulfat, das durch Einverleibung o, i 5 % Pb O und 0,150/0 Pb 02 enthält, werden mit Wasser angefeuchtet und brikettiert. Die Formlinge werden vorerhitzt und bei 6oo° innerhalb 2 bis 3 Stunden mit Wasserstoff reduziert Beispiel 3 i ooo kg Natriumsulfat werden o, 15 % Vanadinpentoxyd zugesetzt. Nach Anfeuchten, Brikettieren und einer Vorerhitzung wird die Reduktion mit Wasserstoff bei 6oo° durchgeführt.Example 2 100 g of sodium sulfate, which contains 0.15% Pb O and 0.150/0 Pb O2 by incorporation, are moistened with water and briquetted. The moldings are preheated and 6oo ° within 2 to 3 hours with hydrogen reduces Example 3 i ooo kg of sodium sulfate are o, 1 5% vanadium pentoxide was added. After moistening, briquetting and preheating, the reduction is carried out with hydrogen at 600 °.
