A study of Multi-Functional Membrane Filters made of Fine Catalyst Particles

<div class="section abstract"><div class="htmlview paragraph">A multi-functional membrane filter was developed through deposition of agglomerated Three-Way Catalyst particles with a size of 1 ~ 2 microns on the conventional bare particulate filter. The filtration efficiency reaches almost 100 % from the beginning of soot trapping with a low pressure drop and both reductions of NO and CO emission were achieved.</div></div>
