1. A system comprising:
a reactor comprising an inlet and an outlet, wherein the reactor contains an amount of catalyst, wherein the amount of catalyst is absorbed with carbon dioxide, and wherein when steam is injected via the inlet pushes the catalyst out of the outlet;
a regenerator having an inlet, a first outlet and a second outlet, wherein the regenerator is fed the amount of catalyst absorbed with carbon dioxide via the inlet, wherein carbon dioxide is desorbed from the amount of catalyst absorbed with carbon dioxide within the regenerator, wherein carbon dioxide exits via the first outlet, and wherein the amount of catalyst which is not absorbed with carbon dioxide exits via the second outlet;
a first pump having an inlet and an outlet, wherein the first pump is configured to assist in the desorption of the carbon dioxide from the amount of catalyst absorbed with carbon dioxide in the regenerator by drawing the desorbed carbon dioxide from the first outlet of the regenerator via the inlet, and wherein the first pump is configured to output carbon dioxide via the outlet; and
a photocatalytic reformer having a radiation source, at least one inlet and at least one outlet, wherein the photocatalytic reformer contains an amount of photocatalyst, wherein the photocatalytic reformer is configured to receive carbon dioxide output by the regenerator via the at least one inlet, wherein the reformer is configured to output methane and oxygen via the at least one outlet, and wherein the reactor receives at least some of the methane output by the photoactivity reformer.
