  • Reactor, a retained catalyst structure, and a method for improving decomposition of polysulfides and removal of hydrogen sulfide in liquid sulfur
    Patent number: 8361432
    Abstract: Disclosed is a reactor, a retained catalyst structure, and a method for increasing the rate of decomposition of polysulfides and removal of hydrogen sulfide in liquid sulfur. The reactor, the retained catalyst structure, and the method include a retained catalyst structure arranged and disposed for contacting a first stream and a second stream in a reactor including a catalyst. The catalyst increases the rate of decomposition of polysulfides and facilitates the removal of hydrogen sulfide in the liquid sulfur of the first stream with the second stream. The first stream includes liquid sulfur containing polysulfides and dissolved hydrogen sulfide. The second stream includes an inert gas or a low oxygen-containing gas.
