Abstract
The invention relates to a reactor () and a process for continuously preparing HS by converting a reactant mixture which comprises essentially gaseous sulfur and hydrogen over a catalyst, comprising a sulfur melt () at least in a lower subregion () of the reactor (), into which gaseous hydrogen is introduced. The catalyst is arranged in at least one U-shaped tube () which is partly in contact with the sulfur melt (), the at least one U-shaped tube () having at least one entry orifice () on a limb () above the sulfur melt (), through which the reactant mixture can enter the U-shaped tube () from a reactant region () of the reactor (), having a flow path within the at least one U-shaped tube, along which the reactant mixture can be converted in a reaction region comprising the catalyst (), and having at least one exit orifice () in another limb () through which a product can exit into a product region ().
