Improvement of V2O5-WO3/TiO2 Supported Catalytic Sheet Filter for Simultaneous Reduction of NOx and Particulates

Phule A. D., Choi J. H., and Kim J. H.
Abstract—Improvement of V2O5-WO3/TiO2 (VWT) supported catalytic sheet filter (SF) has been achieved by using a simple dip coating method with varied concentration of ball milled catalyst coating solution (10-30 wt%) and discussed their NO conversion performances at different reaction temperature (220-380 ˚C). Increase in the catalyst concentration more than 15 wt% it observed the bimodal particle size distribution with the particle size of ~1 micron and >2 micron, which leads to increase in pressure loss of catalyst filter as result to improve the NO conversion performance from 50% (BM10SF) to more than 90% (BM25SF and BM30SF) at reaction temperature range of 260-360 ˚C with Nx leakage less than 50 ppm in the reaction temperature range of 280-340 ˚C. Microstructural study with the help of an optical images explained the surface morphology of the SF with empty and buried (with VWT catalyst) pores. The filtration rate was less than 0.01 m / s, the NO conversion rate of 90% or more was achieved.

Index Terms—Ball milling, dip coating, NOx and particulates reduction, SCR catalyst, V2O5-WO3/TiO2 catalytic sheet filter.
