Preparation of Wet-proofed Catalyst for Tritium Removal

Abstract

Wetproofed catalysts have been developed for the hydrogen isotopic exchange reaction between hydrogen gas and liquid water. A styrene divinylbenzene copolytner (SDBC) was selected as effective support of the hydrophobic Pt catalyst. Preparation conditions and physical properties of the SDBC were investigated experimentally. The SDBC having the larger pore size, higher surface area and larger particle size were prepared by the particular solvent and stirring speed. The H2 adsorption isotherm on a supported Pt catalyst was measured and the hydrogen isotopic exchange reaction was verified in the exchange column.
