Abstract
Catalysts for the flue gas denitrification via the SCR process (selective catalytic reduction) up by the catalytic active oxides of Ti, V and W totally, own some disadvantages (thermal and mechanical stability, high content of heavy metal ions, disposal of waste catalysts), which could be avoided by a supported catalyst. A supported catalyst was produced by coating a ceramic support (cordierite honeycomb) with the catalytic active component dip coating via a sol gel process from titanium-tetraethoxide, vanadyl-tripropoxide and tungsten-hexachloride in the sol stage. Structure e.g. pore size distribution and catalytic activity were determined.
