Abstract

A system for producing hydrogen gas from biomass is disclosed that includes a first reaction chamber having one or more hydroxides, a Ni/ZrO 2 catalyst, and a source of moistened seaweed biomass therein. A heat source is in communication with the first reaction chamber. One or more product streams exit the first reaction chamber including, hydrogen gas, a carbonate, or combinations thereof. A recycle stream provides recycled hydroxide to the first reaction chamber and the product stream is produced as a result of reaction of the seaweed biomass source with the one or more hydroxides in the presence of the Ni/ZrO 2 catalyst.

First claim

What is claimed is:

1 . A system for producing hydrogen gas from biomass comprising:
a first reaction chamber having therein one or more hydroxides, a nickel catalyst, and a source of moistened seaweed biomass; a heat source in communication with the first reaction chamber; one or more product streams exiting the first reaction chamber including hydrogen gas, a carbonate, or combinations thereof; and a recycle stream for providing recycled hydroxide to the first reaction chamber;
wherein the one or more product streams are produced as a result of reaction of the seaweed biomass source with the one or more hydroxides in the presence of the nickel catalyst.

2 . The system according to claim 1 , further comprising at least an additional reaction chamber in fluid communication with the first reaction chamber, the additional reaction chamber having an additional hydroxide therein.

3 . The system according to claim 1 , wherein the one or more hydroxides includes sodium hydroxide, potassium hydroxide, calcium hydroxide, or combinations thereof.

4 . The system according to claim 2 , wherein the additional hydroxide includes sodium hydroxide, potassium hydroxide, calcium hydroxide, or combinations thereof.

5 . The system according to claim 1 , wherein the one or more catalysts is Ni/ZrO 2 .

6 . A method of producing hydrogen gas from biomass comprising:
providing a reaction medium including a moistened seaweed biomass, one or more hydroxides, and a nickel catalyst; performing a thermal treatment of the reaction medium at a temperature between about 400° C. and about 600° C. to produce a hydrogen product and a carbonate product; and recycling the carbonate product as a recycled hydroxide.

7 . The method according to claim 6 , wherein the reaction temperature is about 500° C.

8 . The method according to claim 6 , wherein the one or more hydroxides is sodium hydroxide, potassium hydroxide, calcium hydroxide, or combinations thereof.

9 . The method according to claim 6 , further comprising sequestering carbon dioxide formed during thermal treatment of the reaction medium in at least a second hydroxide.

10 . The method according to claim 6 , wherein the thermal treatment is performed below supercritical pressure.

11 . The method according to claim 10 , wherein the thermal treatment is performed at about atmospheric pressure.

12 . The method according to claim 7 , wherein the seaweed biomass includes brown seaweed, green seaweed, red seaweed, or combinations thereof.

13 . The method according to claim 8 , wherein the one or more catalysts is Ni/ZrO 2 .

14 . A system for producing hydrogen gas from biomass comprising:
a first reaction chamber including a reaction medium including one or more hydroxides and a source of moistened seaweed biomass; an additional reaction chamber including a Ni/ZrO 2 catalyst and one or more additional hydroxides, a heat source in communication with at least the first reaction chamber; one or more product streams exiting the first reaction chamber including hydrogen gas, a carbonate, or combinations thereof; and a hydroxide recycle stream in communication with the one or more product streams and the first reaction chamber;
wherein the product stream is produced as a result of reaction of the seaweed biomass source with the one or more hydroxides in the presence of the Ni/ZrO 2 catalyst.

15 . The system according to claim 14 , wherein the one or more hydroxides includes sodium hydroxide.

16 . The system according to claim 14 , wherein the hydroxide recycle stream includes one or more hydroxides recycled from a carbonate product stream.

17 . The system according to claim 14 , wherein the one or more additional hydroxides is sodium hydroxide, potassium hydroxide, calcium hydroxide, or combinations thereof.

18 . The system according to claim 14 , wherein the seaweed biomass includes brown seaweed, green seaweed, red seaweed, or combinations thereof.

19 . The system according to claim 14 , wherein the heat source is configured to maintain a reaction temperature between about 400° C. and about 600° C. to produce a hydrogen product and a carbonate product.

20 . The system according to claim 14 , wherein the reaction temperature is about 500° C.
