Systems useful for the production of hydrogen and/or carbon dioxide

A vessel comprising:

• an input,
• an output,
• a first material, and
• a second material;
• wherein:
• the first material is positioned between the input and the output,
• the second material is positioned between the input and the output,
• the first material is configured to convert a first fluid into a second fluid,
• the second material is configured to convert the second fluid into a third fluid, and
• the first fluid comprises:
• a carbon containing compound,
• a hydrogen containing molecule that is not a hydrocarbon, or
• a combination of a carbon containing compound and a hydrogen containing molecule that is not a hydrocarbon;
• (i) when the first fluid comprises a carbon containing compound:
• the second fluid comprises carbon dioxide and at least one impurity;
• the third fluid comprises carbon dioxide and optionally at least one impurity;
• and
• the concentration of carbon dioxide in the third fluid is greater than the concentration of carbon dioxide in the second fluid;
• (ii) when the first fluid comprises a hydrogen containing molecule that is not a carbon containing compound:
• the second fluid comprises water, and at least one impurity;
• the third fluid comprises water and optionally at least one impurity;
• and
• the concentration of water in the third fluid is greater than the concentration of water in the second fluid;
• (iii) when the first fluid comprises a combination of a carbon containing compound and a hydrogen containing molecule that is not a carbon containing compound:
• the second fluid comprises carbon dioxide, water, and at least one impurity;
• the third fluid comprises carbon dioxide, water and optionally at least one impurity;
• and
• the concentration of carbon dioxide in the third fluid is greater than the concentration of carbon dioxide in the second fluid.

A process, the process comprising the steps of:

• contacting a first fluid with a first material in a first vessel to produce a second fluid, and contacting the second fluid with a second material in a second vessel to produce a third fluid;
• wherein:
• the first fluid comprises:
• a carbon containing compound,
• a hydrogen containing molecule that is not a hydrocarbon, or
• a combination of a carbon containing compound and a hydrogen containing molecule that is not a hydrocarbon;
• (i) when the first fluid comprises a carbon containing compound:
• the second fluid comprises carbon dioxide and at least one impurity;
• the third fluid comprises carbon dioxide and optionally at least one impurity;
• and
• the concentration of carbon dioxide in the third fluid is greater than the concentration of carbon dioxide in the second fluid;
• (ii) when the first fluid comprises a hydrogen containing molecule that is not a carbon containing compound:
• the second fluid comprises water, and at least one impurity;
• the third fluid comprises water and optionally at least one impurity;
• and
• the concentration of water in the third fluid is greater than the concentration of water in the second fluid;
• (iii) when the first fluid comprises a combination of a carbon containing compound and a hydrogen containing molecule that is not a carbon containing compound:
• the second fluid comprises carbon dioxide, water, and at least one impurity;
• the third fluid comprises carbon dioxide, water and optionally at least one impurity;
• and
• the concentration of carbon dioxide in the third fluid is greater than the concentration of carbon dioxide in the second fluid.
