Carbon Dioxide Separation and Syngas Purification Via Capture and Sequester Ability of Gas Hydrate Nano-Zeolites

This research investigated the carbon dioxide-nitrogen separation efficiency in new nano-zeolite structures named gas hydrates, both for syngas purification as a feed gas for petrochemical plants and for the sequestration potential of carbon dioxide. In a series of experiments simulated under ocean sediment environments, the biosurfactants emulsion and Rhamnolipid showed favorable catalysis of carbon dioxide hydrate formation. This research showed that a potentially cost effective hydrate separation technology applied to nitrogen-carbon dioxide gas, representative of a flue gas, can be improved by adding surfactants as zeolite motivators. It was found that biosurfactants give some beneficial effect on carbon dioxide hydrate formation and might be used to assist carbon dioxide sequestration or to displace natural gas from hydrates already. Our experiments show that a carbon dioxide-philic surfactant for zeolite stimulation, was found that dramatically improved carbon dioxide capture from a gas mixture (flue gas or syngas) in a carbon dioxide-gas hydrate process.
