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 (CO) is used as the regeneration and activation media. This method of a single step regeneration and activation using COis 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 COand carbon.

Regeneration and activation of catalysts for carbon and syngas production

Disclosed is a high yield, high selectivity and high conversion method to produce Dimethyl Carbonate (DMC) from carbon dioxide (CO) 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.
