Abstract
In order to prepare the catalytic filters based on V2O5/TiO2 for the removal of NOx and particulate simultaneously from the flue gas stream, the experimental study was carried out. The effective method to support TiO2 layer in the pore of the commercial ceramic filter element was developed. TiO2 layer was supported on the filter element by three methods; impregnation with Ti solution, sol-gel dip coating and sol-gel centrifugal coating. As the model test to check the catalytic activity, NO reduction in the oxidizing stream was investigated. The catalytic filter prepared by applying the centrifugal force showed the best NO conversion more than 90% when the face velocity was 0.02 m/sec. This was a very promising result for the application of catalytic filter for the flue gas control at high temperature. The supporting methods by the impregnation and dip coating were not recommended because the TiO2 layer was concentrated in the exterior layer of the filter element.
