Abstract: A method for recycling a carbon-containing greenhouse gas emissions such as carbon dioxide and methane (natural gas) or a hydrocarbon homolog thereof. The method includes the steps of capturing the emissions, sequestering them in an underground or undersea storage area, withdrawing them from the storage area after storage therein, and converting them to carbon-containing compounds such as methanol, dimethyl ether and derived products.

Abstract: In one example, we describe a method and system that uses iron oxide as its sole sorbent, specifically micron-sized nano-porous iron oxide particles. The sorbent is housed inside a horizontally rotating sorbent bed. The horizontally rotating sorbent bed is housed inside of a larger secondary compartment. At the top of the secondary compartment, there is an escaped sorbent particle containment membrane. One example uses a self-cleaning horizontally rotating sorbent drum membrane design that unclogs particulates lodged in the membrane by reversing particulate air flow direction during a small portion (e.g., about 20 degrees) of each full 360 degree rotation of the drum. When air flow passes through the porous horizontally rotating sorbent drum's membrane, which occurs at the location where the rotating sorbent bed membrane comes into contact with the air feed manifold, particulates are air-dislodged from the inner facing surface of the drum's membrane. Other variations are discussed.
