Reduction of the Preparation Cost for the Commercial Hydrophobic Platinum Catalyst
Wolsong Tritium Removal Facility (WTRF) is being constructed at Wolsong Nuclear Power Plant for reduction of the radiation hazards from tritium. The Liquid Phase Catalytic Exchange (LPCE) process developed by KAERI and KEPRI was selected for the transfer process in WTRF. Approximately 2,000 litres of the hydrophobic platinum catalyst will be charged in the LPCE column. It was estimated that more than half of material cost for the catalyst preparation arised from H2PtCl6 as a platinum precursor and high purity hydrogen gas as a reducing agent. In order to reduce material costs for the catalyst preparation, various catalysts were prepared and characterized using three kinds of H2PtCl6 and two kinds of high purity hydrogen gas. It appears from the experiment that characteristics of the catalyst does not depend on both a kind of H2PtCl6 and purity of hydrogen in the experimental conditions.
