Ordered mesoporous carbon as a support for palladium-based hydrodechlorination catalysts
Abstract
Ordered mesoporous carbon (OMC) was employed as a support for palladiumnanoparticles in catalysts for the gas phase hydrodechlorination (HDC)of trichloromethane (TCM). 1 wt% palladium was incorporated using threemethods: incipient wetness (IW); a dilute solution (DS) method; and asolid-liquid (SL) method. The effect of the preparation method oncatalyst structure and activity was investigated. Catalyst compositionand nanostructure were studied using gas physisorption, highspecification transmission electron microscopy and X-ray photoelectronspectroscopy. Catalytic conversion and product selectivities weredetermined in steady-state activity tests at temperatures between 70 and300 °C. Two of the catalysts (IW and DS) showed excellent dispersion offine Pd nanoparticles of average diameter ~2 nm. These materials showedexcellent activity for HDC of TCM which compares favourably with theperformance reported for Pd on amorphous carbon catalysts. In addition,they showed relatively high selectivities to the more valuable higherhydrocarbons. However, the SL method gave rise to catalysts with largerparticles (~3 nm) and a less uniform palladium distribution. Thisresulted in lower conversion and lower selectivities to higherhydrocarbons and in more severe catalyst deactivation at the highestreaction temperatures.
