Description
The performance of mesoporous silica catalysts in hydrolysis of cyclosiloxanes was measured in a fixed-bed reactor under various experimental conditions in order to protect the hydrogen recombination catalyst used in the off-gas treatment system of a boiling water reactor from poisoning by cyclosiloxanes. The hydrolysis of decamethyl cyclopentasiloxane (D5) over Zr-SBA15 and Ti-SBA15 was found to depend on the residence time but not on the reaction temperature or the amount of catalyst loaded on the honeycomb (100–150 g/L). The conversion of D5 by hydrolysis over Zr-SBA15 was 0.95 at 423–523 K with a linear velocity of 2.9 m/s in a honeycomb of 120 mm in height. The hydrolysis of D5 over Zr-SBA15 and Ti-SBA15 was a first-order reaction and the conversion of D5 could be predicted from an Arrhenius plot. In a DSS durability test, the performance of Ti-SBA15 declined less than that of Zr-SBA15.
