Research Abstract |
Characteristic structural changes that occur in hydrates and semi-clathrate hydrates are important for understanding hydrate properties for gas separation application. In this work, gas adsorption equilibria for H_2 and for CO_2 with the organic liquids clathrate hydrate particles and with the quaternary ammonium salts semi-clathrate hydrate particles. The higher temperature, the H_2/CO_2 selectivity was higher. In 2.6 mol TBAB semi-clathrate hydrate, this value is higher than 100, the hydrates was confirmed adaptability to the gas separation process.
