Abstract
TS-1 monolithic catalysts were prepared on cordierites honeycomb ceramics supports by dip-coating method in TS-1/H2O suspension. The cordierites honeycomb ceramics supports were treated with different methods, such as coated with a thin layer of sodium silicate, immersed in 0.5N hydrochloric acid. The monolithic catalysts were characterized by Scanning Electron Microscopy. The distribution of TS-1 Catalysts onto supported was observed. The immobilized stability of TS-1 monolithic catalysts was evaluated by ultrasonic cleaning and washing out experiment. TS-1 catalysts were uniformly deposited onto inner smoothed surface of cordierites honeycomb ceramics supports, which ware coated sodium silicate film. And experiment data proved that TS-1 catalysts may be firmly immobilized onto supports coated sodium silicate.
