A study on the polymer catalyst manufacturing technology

Heavy water is used as moderator and coolant in Pressurized Heavy Water Power Plants. According to the governmental long-term plan for power supply, Korea is scheduled to construct new four pressurized heavy water power plants till the year 2006. Total heavy water demand for these plants would be 1988 Mg during the period 1992-2006. Reformed hydrogen processes is considered best suited to Korea. Hydrophobic catalysts for this process were manufactured and the performance of hydrogen isotope exchance was investigated. The overall mass transfer coefficients varied between 0.004 and 2.295 m3 HD/m3 Bed.sec. and heavy water separation processes using the catalysts were optimized. (Author)
