The invention relates to a method and a device for the continuous production of hydrogen sulphide H2S, wherein the crude gas stream containing the H2S generated in the production contains polysulphanes (H2Sx). The crude gas stream is passed through a catalytically active material (41) contained in a vessel (42) at a temperature of 114 to165 DEG C and the sulphur generated is trapped in the sump (43) of the vessel (42) and recycled for production of H2S. The device according to the invention, comprises a reactor (1) for the reaction of sulphur and hydrogen, a cooler (40), connected to the reactor (1), for cooling a crude gas stream containing H2S withdrawn from the reactor (1) to 114 to 165 DEG C, a vessel (42) connected to the cooler (40) and containing catalytically active material (41) with a sump (43) for trapping sulphur generated in the vessel (42) from the crude gas stream containing polysulphanes at 114 to 165 DEG C and a line (44), connected to the sump (34) of the vessel (42)which opens out in the cooler (40) or in the reactor (1) for the recycling of sulphur.
