2 Research Significance The ceramic membrane has been getting more attention and is being rapidly developed for the application of CO 2 separation / recovery in recent years. This is due to the worldwide restrictions against emission of CO 2 gas which causes the green-house effect. In particular, ceramic membranes have good thermal, chemical and structural stability, long life application, and capacity of having catalytic and electrical properties. In spite of their excellent properties, the potential applications of ceramic membranes for CO 2 / gas separation have not been fully realized because of current limitations such as lack of confidential manufacturing techniques, difficulty of microstructure control, and high production cost. Intensive studies should be continued in future for the development of these membranes and their practical application to CO 2 / gas separation. In this work, zeolite composite membranes (ZSM-5 and NaY types) have been synthesized using a hydrothermal treatment of porous α-alumina tubes in the reaction solution which was optimized for making each type of zeolite crystals. The CO 2 separation efficiency of synthetic zeolite membranes has been evaluated via measuring and examining both the gas permeabilities of various gases and the separation factors of CO 2 to N 2 in their mixtures. The effects of process parameters on CO 2 separation of zeolite membranes are also discussed. NanoPore Materials Lab.

3 Research Objectives - Optimization of zeolite types in the Na-Si-Al system for maximizing the high temperature CO 2 / N 2 separation efficiency - Development of the thin film technique for forming zeolite membrane layers on the porous ceramic support - Investigation of CO 2 / N 2 gas permeation and separation mechanisms in zeolite composite membranes at ordinary and high temperatures - Establishment of techniques for evaluating microstructures and defects of composite membranes - Development of zeolite composite membranes having the following performances and specifications: Time Item Membrane Type Mechanical Strength Pore size of Membrane layer Operating Temperature Permeability of mixed gas CO 2 / N 2 separation factor High temperature stability Final Tubular (L: 10 cm, D out < 1 cm) > 15 kg f / cm < 6.0 > 250 o C > 100 barrer > 50 > 30,000 h 1st year Tubular (L: 10 cm, D out < 1 cm) > 15 kg f / cm < 10 > 25 o C > 100 barrer > 10 > 100 h

11 Conclusions ZSM-5 and NaY type zeolites could be synthesized by the hydrothermal treatment of each reaction solution at 170 o C for 24h and 100 o C for 7h, respectively. Tubular zeolite composite membranes were also synthesized by the hydrothermal treatment of a α-alumina tube (pore size 0.1 ~ 1.0 µm) in the synthesis solution at the same conditions as those in case of powder synthesis. The ZSM-5 zeolite composite membrane surface-modified with the polymeric silica sol showed a high CO 2 / N 2 separation factor of 17.3 and a large permeability of 10-8 mol / m 2. s. Pa at room temperature. The permeation / separation mechanism of CO 2 through zeolite membranes was known to be a adsorption and surface diffusion. Compared to ZSM-5 zeolite membranes, the NaY type zeolite composite membrane under being developed seems to be more promising in practical points such as low synthesis temperature and easy surface modifications like ion-exchanging for applications of CO 2 or other gas separation.
