Abstract

A solution is provided for CO₂ and other green houses gas reduction at the Coal Fired Power Plants (CFPP). The methods and devices disclosed herein provide an inexpensive source of hydrogen and a hydrogen generating system powered by on-site excess heat generated at the CFPP without producing additional CO₂ emission.

Claims

1. A system for producing hydrocarbon compounds comprising:

a. a hydrogen producing unit containing a hydrogen producing catalyst having aluminum, copper, and silver;

b. a coal furnace producing heat and carbon dioxide, wherein the coal furnace receives oxygen from the hydrogen producing unit, wherein the coal furnace supplies hot water to heat up the hydrogen producing unit and the hot water becomes cold water to circulate back from the hydrogen producing unit to cool a heat exchanger at the coal furnace;

c. a hydrocarbon converter, wherein the hydrocarbon converter receives hydrogen from the hydrogen producing unit; and

d. a methanol converter coupled with the hydrogen producing unit, wherein the methanol converter receives hydrogen from the hydrogen producing unit, separately receives the carbon dioxide from the coal furnace, and outputs an amount of 10%-30% of ethane to the coal furnace and 70%-90% of methanol to the hydrocarbon converter, wherein the ethane generates heat at the coal furnace as a source of heat for the hydrogen producing unit, wherein the hydrogen from the hydrogen producing unit is split into a first portion for supplying to the methanol converter and a second portion for supplying to the hydrocarbon converter.

2. The system of claim 1, wherein the furnace comprises a coal fired power plant.

3. The system of claim 1, wherein the furnace comprises a coal-combustor.

4. The system of claim 1, wherein the methanol converter comprises a CO₂-to-methanol converter.

5. The system of claim 1, wherein the hydrocarbon converter comprises a methanol-to-gasoline converter.

6. The system of claim 1, wherein the heat generates the hot water to be supplied to the hydrogen producing unit.

7. A system for producing hydrocarbon compounds comprising:

a. a hydrogen producing unit containing a hydrogen producing catalyst having aluminum, copper, and silver;

b. a coal furnace producing heat and carbon dioxide, wherein the coal furnace receives oxygen from the hydrogen producing unit, wherein the coal furnace supplies hot water to heat up the hydrogen producing unit and the hot water becomes cold water to circulate back from the hydrogen producing unit to cool a heat exchanger at the coal furnace;

c. a hydrocarbon converter, wherein the hydrocarbon converter receives hydrogen from the hydrogen producing unit; and

d. an ethanol converter coupled with the hydrogen producing unit, wherein the ethanol converter receives hydrogen from the hydrogen producing unit, separately receives the carbon dioxide from the coal furnace, and outputs an amount of 30% methane to the coal furnace and carbon monoxide to the hydrocarbon converter, wherein the methane generates heat at the coal furnace as a source of heat for the hydrogen producing unit, wherein the hydrogen from the hydrogen producing unit is split into a first portion for supplying to the ethanol converter and a second portion for supplying to the hydrocarbon converter.

8. The system of claim 7, wherein the furnace comprises a coal fired power plant.

9. The system of claim 7, wherein the furnace comprises a coal-combustor.

10. The system of claim 7, wherein the ethanol converter comprises a CO₂-to-ethanol converter.

11. The system of claim 7, wherein the heat generates the hot water to be supplied to the hydrogen producing unit.

12. The system of claim 7, wherein the hydrocarbon converter comprises a Fischer-Tropsch processing unit.

13. The system of claim 7, wherein the hydrocarbon converter comprises a paraffin producing unit.

14. The system of claim 7, wherein the hydrocarbon converter comprises a naphtha, kerosene, or diesel producing unit.
