Adsorption and desorption characteristics of barium oxide at high temperature
چکیده انگلیسی
Relaxation time for adsorption ranged from 4 to 9 min depending on the preparation methods and that for desorption was 6 min regardless of the preparation methods. Breakthrough experiment with the sorbent prepared by the sol-gel method was performed. The adsorption breakthrough curves at 600 °C showed two plateau regions. One was at about 3.5%, and the other was 20%. The first plateau region is related to the sharp transition point of the oxygen adsorption isotherm. Though the relaxation time for adsorption was 6 min, the time required from the end of the first plateau to the beginning of the second plateau was just 2 min. During the desorption, a plateau region at 3.5% of oxygen concentration was observed regardless of the desorption flow rate.
