The use of formate-based ammonia precursors as alternatives to urea in the selective catalytic reduction (SCR) process requires that formic acid released upon their thermolysis in the hot exhaust is rapidly decomposed to carbon dioxide. This work aims at t ...
The kinetics and the mechanism of the selective redn. of nitric oxides (NOx) by hydrogen is studied on a trimetallic Pt-Mo-Co/a-Al2O3 catalyst under oxidizing conditions. This system is interesting in view of an exhaust gas control of power plants or lean- ...
The Swiss limit for NOx exhaust gas emissions from decentralised electrical power and heat cogeneration units using stationary I.C. engines operating on natural gas, despite a recent increase from 80 to 250 mg/mN3 (5% O2), remains the most severe in force ...
The kinetics and the mechanism of the selective reduction of nitric oxides (NOx) by hydrogen is studied on a trimetallic Pt–Mo–Co/a-Al2O3 catalyst under oxidising conditions. This system is interesting in view of an exhaust gas control of power plants or l ...
NOx is removed from gas by redn. with at. N in a plasma jet at 50-1000 M and 5000-6000 K. The NOx-contg. gas is injected into the plasma jet at 30 m/s resulting in the reaction NO + N = N2 + O. A high redn. degree of NOx is attained with no salt wastes. Th ...
Real-world vanadium-based catalysts for the selective catalytic reduction (SCR) of NO with NH3 are occasionally exposed to high temperatures, which can induce catalyst aging. In this work, a 2.0 wt% V2O5/WO3-TiO2 catalyst based on commercial WO3-TiO2 was l ...
Co-impregnation of vanadia and tungsta on titania produced highly active catalysts for the reduction of nitrogen oxides with ammonia but showed aging tendencies at temperatures around 600 °C. In order to preserve their low temperature activity after hydrot ...
A medium size diesel engine converted to natural gas operation on the Otto principle has been studied under stoichiometric and lean burn operation in order to evaluate the potential to reduce the NOX exhaust gas emissions below the stringent limit prescrib ...
One possibility for the removal of volatile organic compounds (VOCs) is catalytic oxidation. For the removal of VOCs in low concentration (≲ 3000 ppmv for propane) it is not possible to sustain the required oxidation temperature over the catalyst wit ...
The redn. of NOx with CO and H2 on Pt-Mo/a-Al2O3 catalysts as an alternative for Pt-Rh catalysts was studied for exhaust gas purifn. in lean-mixed engines in oxidizing range. The NOx content has a significant influence on the catalyst activity. The H2/O2 r ...
