Description
Abstract: This paper presents the results of experimental study of the columns packed with Palladium deposited on kieselguhr (Pd/k). The characteristic of pressure resistance and separation of hydrogen isotopes of the Pd/k column was investigated. The corresponding relationships among pressure resistance characteristics of Pd/k separation column and Pd/k material physicochemical properties, column structure, and the filling coefficient were determinated. The relation curve between the pressure drop per unit length and the velocity was established under the different inner diameter. And the analysis model between pressure resistance and velocity was set up by calculating the pressure resistance characteristics parameters under certain condition. The separation of hydrogen isotopes (H, D) is performed by displacement chromatography on palladium packed column. The results showed that the Van Deemter model gives a fairly good analysis of the process. Under the experimental condition, the minimum of height equivalent to a theoretical plate (HETP) is less than 0.64cm, which shows the high separation efficiency of packed column for hydrogen isotope separation. The results indicate that the Pd/k column can realize the separation of hydrogen isotopes. This hydrogen isotope processing can apply to the separation of hydrogen isotope gases of the D/T fuel cycle system for fusion reactor.
