Abstract: The present subject matter is directed to a system and method for producing carbon and syngas from carbon dioxide (CO2). The system includes a first reactor (7) for producing solid carbon (15) from a feed including CO2 and a volatile organic compound such as methane (1), and a second reactor (20) for producing syngas. Reactions in the first reactor (7) are conducted in a limited oxygen atmosphere. The second reactor (20) can use dry reforming, steam reforming, and/or partial oxidation reforming to produce the syngas (22).

Abstract: Disclosed is high conversion and high carbon yielding CARGEN catalyst and a method of preparing the same. The catalyst comprises transition metals that may be supported or unsupported. The preparation method involves mixing a metal material with or without a support in a standard ball milling apparatus to produce a fine and homogenous solid mixture of the transition metal oxide and support. The catalyst is used in the CARGEN system.

Abstract: A method to regenerate and reactivate catalysts used for a carbon and syngas production reaction including a DRM or CARGEN reaction is developed. Carbon dioxide (CO2) is used as the regeneration and activation media. This method of a single step regeneration and activation using CO2 is more effective than the existing conventional two-step process that includes separate reduction and oxidation steps. This method produces pure carbon monoxide (CO) as a byproduct from the regeneration process by utilizing CO2 and carbon.

Abstract: Disclosed is a high yield, high selectivity and high conversion method to produce Dimethyl Carbonate (DMC) from carbon dioxide (CO2) and methanol (MeOH) using optimized concentration of ethylene oxide as water scavenger. The method provides an alternative and optimized solution towards the problem of formation of water in DMC synthesis by reporting optimal feed ratio and scavenger to MeOH feed ratio. The disclosure also discloses an optimal pressure condition that could have significant impact on economy of compression of the feed to the DMC reactor.
