Abstract: A rotary moving bed and process for separating a carbon dioxide from a gas stream is disclosed. The rotary moving bed can have a rotational assembly rotating on a vertical axis, and a plurality of sorbent cells positioned horizontally to the axis of rotation that fills a vertical space in the moving bed, where the sorbent cells adsorb the carbon dioxide by concentration swing adsorption and adsorptive displacement. The sorbent can be regenerated and the carbon dioxide recaptured by desorbing the carbon dioxide from the sorbent using concentration swing adsorption and desorptive displacement with steam. The gas flows in the system flow in a direction horizontal to the axis of rotation and in a direction opposite the rotational movement of the sorbent cells.

Abstract: A system and method for separating and/or purification of CO2 gas from a CO2 feed stream is described. The system and method include a plurality of fixed sorbent beds, adsorption zones and desorption zones, where the sorbent beds are connected via valve and lines to create a simulated moving bed system, where the sorbent beds move from one adsorption position to another adsorption position, and then into one regeneration position to another regeneration position, and optionally back to an adsorption position. The system and method operate by concentration swing adsorption/desorption and by adsorptive/desorptive displacement.

Abstract: A process for separating a carbon dioxide from a gas stream is disclosed. The process can include passing the gas stream over a sorbent that adsorbs the carbon dioxide by concentration swing adsorption and adsorptive displacement. The sorbent can be regenerated and the carbon dioxide recaptured by desorbing the carbon dioxide from the sorbent using concentration swing adsorption and desorptive displacement. A carbon dioxide separation system is also disclosed. Neither the system nor the process rely on temperature swing or pressure swing adsorption.

Abstract: Systems and methods are provided for performing CO2 sorption and regeneration processes that can take advantage of phase changes between solutions of amine-CO2 reaction products and precipitate slurries, where the slurry particles can include solid precipitates formed based on the amine-CO2 reaction products. An amine solution can be used to capture CO2 from a gas phase stream. During this initial capture process, the amine-CO2 reaction product can remain in solution. The solution containing the amine-CO2 reaction product can then be exposed to a set of conditions which result in precipitation of a portion of the amine-CO2 reaction product to form a slurry. The precipitate slurry can be passed into one or more release stages where the conditions for the slurry are altered to allow for release of the CO2.

Abstract: Disclosed is a process for converting organic material of oil-shale to predominantly liquids. The oil-shale is first heated to a temperature from about 360.degree. C. to 475.degree. C. in an inert atmosphere. The resulting liquids and gases are collected and the residue is extracted with a microemulsion capable of extracting organic material from the heat treated oil-shale.
