Abstract: Sulfur arc lamp includes an arc chamber that has a cathode and an anode both made of refractory metals that include pure tungsten, pure molybdenum, tungsten alloy, molybdenum alloy or a composite in which tungsten is at least 90%, or a composite in which molybdenum is at least 90%; a plasma initiation gas filling the plasma chamber; power supply configured to switch on and off electric arc discharge between the cathode and anode; second chamber connected to the arc chamber for releasing sulfur vapor into the plasma arc chamber, thereby creating a sulfur-containing plasma gas when the discharge occurs, and configured to selectively remove the sulfur vapor from the sulfur-containing plasma gas when the discharge occurs, wherein the second chamber is configured to reduce a concentration of the sulfur vapor in the arc chamber below 1013 molecules per cm3 before the electric arc discharge is off.

Abstract: Device for hydrogen sulfide plasma dissociation includes a plasma chemical reactor including an arc plasma generator that has a cathode and an anode; the anode having a working surface for contacting hydrogen sulfide plasma, wherein the working surface is made from a material that includes stainless steel, tungsten or molybdenum; the cathode having a tip for arc attachment where a cathode spot is formed, wherein the cathode tip is made from pure tungsten, pure molybdenum, a tungsten or molybdenum alloy with tungsten as a major component or a composite material in which tungsten or molybdenum is the major component; and a flow path configured to have an inlet for gaseous hydrogen sulfide for dissociation in plasma into hydrogen and sulfur, and an outlet for gaseous products of hydrogen sulfide plasma dissociation. Optionally, the alloy or composite material has up to 10% low work function elements (thorium, cerium, lanthanum, or zirconium).
