NOVELTY - The process comprises introducing a stream of hydrogen sulfide into a reactor chamber (3), applying an electrical current to a resistance wire, energizing the resistance wire disposed in the reactor chamber by passing an electrical current through the resistance wire, contacting the stream of hydrogen sulfide with the energized resistance wire to produce hydrogen gas and elemental sulfur and to cause the hydrogen sulfide to decompose into hydrogen gas and sulfur vapor, and passing the produced hydrogen gas through the membrane and into the flow passageway.    USE - The process is useful for producing hydrogen from hydrogen sulfide, where the hydrogen is useful as a clean burning fuel.    ADVANTAGE - The process is capable of simply and economically producing the hydrogen from the hydrogen sulfide in a convenient manner with high quality and without impurities or contaminants.    DETAILED DESCRIPTION - The process comprises introducing a stream of hydrogen sulfide into a reactor chamber (3), applying an electrical current to a resistance wire, energizing the resistance wire disposed in the reactor chamber by passing an electrical current through the resistance wire, contacting the stream of hydrogen sulfide with the energized resistance wire to produce hydrogen gas and elemental sulfur and to cause the hydrogen sulfide to decompose into hydrogen gas and sulfur vapor, passing the produced hydrogen gas through the membrane and into the flow passageway from which the hydrogen gas is discharged from the chamber through the first outlet, condensing sulfur vapor into liquid sulfur, discharging the liquid sulfur through the second outlet, and removing the hydrogen gas from the reactor chamber. The reactor includes: an outer wall having an interior surface and defining an interior chamber of the reactor; an inlet for introducing the stream of hydrogen sulfide into the interior chamber; a membrane disposed in the interior chamber; a second outlet present in communication with the interior chamber through which sulfur exits the chamber; and a resistance wire disposed adjacent to a membrane. The membrane is permeable to hydrogen gas, defines a flow passageway that is in communication with a first outlet through which hydrogen gas passing through the membrane exits the chamber, and comprises a ceramic. The step of applying electrical current to the resistance wire heats the membrane at a temperature of 150-700 degrees C. A stream of hydrogen sulfide includes natural gas and methane gas. The natural gas remains unreacted in the process. The hydrogen is continually removed by decomposition of the hydrogen sulfide. The methane is continually removed from the reaction chamber.
