Abstract

A process and system for substantially eliminating contaminants from a gas and a gas produced therefrom.

Claims (52)

1 . A process for substantially eliminating contaminants from a gas comprising:

providing the 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;

separating the sulfur from the gas.

2 . The process of claim 1 wherein the hydrocarbon comprises methane.

3 . The process of claim 1 wherein the gas comprises at least one of a natural gas, industrial gas and refining gas.

4 . The process of claim 1 wherein the temperature comprises about 400-700° C.

5 . The process of claim 1 wherein the temperature comprises about at least 115° C.

6 . The process of claim 1 wherein the reactor comprises a pressure of about atmospheric pressure up to 20,684 kPa.

7 . The process of claim 1 further comprising feeding the gas into a hydrogen permeable reactor.

8 . The process of claim 1 wherein the hydrogen permeable reactor comprises a ceramic.

9 . The process of claim 1 further comprising:

providing carbon dioxide at a ratio of about 2 moles of hydrogen sulfide to one mole of carbon dioxide;

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.

16 . The process of claim 12 wherein the temperature comprises about at least 59° C.

17 . The process of claim 12 wherein the reactor comprises a pressure of about atmospheric pressure up to 20,684 kPa.

18 . The process of claim 12 further comprising 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.

19 . The process of claim 12 wherein the gas comprises a ratio of about 2 moles of hydrogen sulfide to one mole of carbon dioxide.

20 . A process for providing hydrogen as a fuel comprising:

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.
