Titanium tungsten powder for SCR denitrification catalyst has the advantages of small grain size, stable performance, uniform appearance and maximum surface area, and is generally prepared by ammonium metatungstate (AMT).
Characteristic
Small grain size, small lattice distortion and stable performance; The particle concentration was the lowest, the morphology was uniform, and the tungsten distribution was the most uniform. The larger the surface area than the surface area, the better the activity of the catalyst.
Preparation
It is prepared by ammonium metatungstate (AMT) preparation, AMT is an ideal precursor for preparing titanium tungsten powder, denitration catalyst for production of titanium tungsten powder, tungsten salt species will produce important influence on the performance of titanium tungsten powder in the end, the different tungsten salt in the dispersion of metatitanic acid pulp and calcined reaction mechanism will be different.
