converting the carbon dioxide to water and at least one of carbon and carsuls;
reducing the carbon dioxide with hydrogen; and
separating the water and the at least one of carbon and carsuls from the gas.
10 . The process of claim 1 further comprising:
oxidizing the hydrogen; and
releasing energy in an exothermic process yielding 10-12 times an absorbed energy required in an endothermic process of converting the hydrogen sulfide to sulfur and hydrogen.
11 . A gas produced from the process of claim 1 .
12 . A process for substantially eliminating contaminants from a gas comprising:
providing the gas having hydrogen sulfide, hydrocarbon and carbon dioxide in a reactor;
passing the gas through a heated area having a temperature of about 50° C.-700° C., the heated area produced by a heating element comprising at least one of a catalyst and a resistance wire;
converting the hydrogen sulfide to sulfur and hydrogen;
reacting the hydrogen with the carbon dioxide to form water and at least one of carbon and carsuls; and
oxidizing the hydrogen with the oxygen of the carbon dioxide; and
separating the sulfur, water and at least one of carbon and carsuls from the gas.
13 . The process of claim 12 wherein the hydrocarbon comprises methane.
14 . The process of claim 12 wherein the gas comprises at least one of a natural gas, industrial gas and refining gas.
15 . The process of claim 12 wherein the temperature comprises about 400-700° C.

storing a gas, having hydrogen sulfide, as a liquefied gas in a container;
providing a reactor that connects to the container, the reactor having a heating element comprising at least one of a catalyst and a resistance wire;
releasing the gas from the container to the reactor;
passing the gas through a heated area, having a temperature of about 50° C.-700° C., produced by the heating element;
converting the hydrogen sulfide to sulfur and hydrogen; and
separating the sulfur from the gas.
21 . The process of claim 20 further comprising filtering the hydrogen through at least one of a hydrogen only permeable membrane and a bed of hydrogen sulfide absorbent.
22 . The process of claim 20 wherein the reactor comprises a hydrogen permeable reactor.
23 . A gas substantially free of contaminants, the contaminants removed by a process comprising:
providing a gas having hydrogen sulfide and hydrocarbon in a reactor;
passing the gas through a heated area having a temperature of about 50° C.-700° C., the heated area produced by a heating element comprising at least one of a catalyst and a resistance wire;
converting the hydrogen sulfide to sulfur and hydrogen; and
separating the sulfur from the gas.
24 . A system for substantially eliminating contaminants from a gas comprising:
a reactor for receiving the gas, having hydrogen sulfide and hydrocarbon; and
a heating element, having at least one of a catalyst and a resistance wire, within the reactor that contacts the gas to produce products substantially free of the hydrogen sulfide.
