Abstract
The present invention relates to a method for preparing lithium sulfide (Li2S) from lithium hydroxide (LiOH) and hydrogen sulfide (H2S), characterised in that the lithium hydroxide is sulfided in a reaction zone (9) comprising at least one moving bed tubular reactor (9a) having the configuration of an ascending vibrating spiral in which the lithium hydroxide (4) flows in countercurrent to an anhydrous gas mixture (10) containing hydrogen sulfide and at least one inert gas.
Claims14
A process for preparing lithium sulfide (Li2S) from lithium hydroxide (LiOH) and hydrogen sulfide (H2S), comprising:
- sulfiding lithium hydroxide in a reaction zone (9) comprising at least one moving bed tubular reactor (9a) having the configuration of an ascending vibrating spiral;
- circulating the lithium hydroxide (4) in countercurrent to an anhydrous gas mixture (10) containing hydrogen sulfide and at least one inert gas.
