catalyst regeneration indicators
after catalyst regeneration, k/k0 ≥95% , catalytic activity generally in accordance with the fresh catalyst.
so2/so3 ≤0.3% , national standard is so2 / so3≤ 1%, can greatly reduce congestion and acid corrosion to the back end equipment such as catalyst, air preheater and so on.
chemical life ≥24000h and physical life ≥50000h.
single hole rate ≥95%, higher than similar factories, flue gas effective contact area increases, improve nox removal rate.
regeneration of catalyst deactivation curve in accordance with new catalyst.
catalyst resource recycling system is the only spent catalyst alkaline extraction technology in domestic, short process, low energy consumption, high product recovery rate, vanadium and tungsten recovery rate to 90%, titanium recovery rate to 95%. it product titanium dioxide, sodium tungstate, ammonium vanadate, titanium tungsten powder efficiently and environmental. as an important chemical raw material back into the market, to realize the green industry cycle.
