sf6 mixture solutions wikipedia in substations2020/12/14Abstract A method has been proposed to convert isotopically modified sulfur hexafluoride to elemental sulfur by the reaction of sulfur hexafluoride with hydrogen in a high frequency discharge: SF6 + 3H2 = S + 6HF. The optimal process conditions (the ratio between the reactants, the pressure in the reactor, the flow rate of the reaction mixture, and the yield of the desired products) are
