Abstract: A multi-stage decomposition reactor and method for thermochemical decomposition (pyrolysis, cracking, direct decomposition) of a hydrocarbon feedstock of various compositions that may include mixtures. The feedstock in a supply flow passing through a heating stage is activated by raising its temperature to a decomposition temperature, dependent on the nature of the feedstock. The physical length of the heating stage and a velocity of flow once activated are tuned such that a heating residence time of the flow is shorter than an average decomposition onset time at the decomposition temperature ( e. g., before 1% or more feedstock decomposition ). The heating stage is followed by a decomposition stage that supports a decomposition residence time that is longer than the average decomposition onset time. A molten material can be present in the decomposition stage that can be rotated to facilitate mopping up of carbon depositions.

Abstract: An electrochemical system, an electrochemical stack and a method for carbon dioxide capture and carbon dioxide recovery. The system has a CO2 capture device where a metal hydroxide base solution reacts with CO2 to produce carbonates and bicarbonates. The electrochemical stack has one or more electrochemical cells, each with a gas diffusion anode having a hydrogen supply, a cathode spaced from the anode to define an electrolysis region between them for a salt solution, a cation exchange membrane in the electrolysis region next to the cathode and a metal hydroxide region separated from the electrolysis region by the cathode. A voltage potential between the anode and cathode produces an acid solution in the electrolysis region, conditions the metal hydroxide base solution in the metal hydroxide region and evolves hydrogen at the cathode. A CO2 evolution device uses the acid and the carbonates and/ or bicarbonates to recover CO2 and to recover the salt solution for reuse in the electrochemical stack.
