文摘

Kinetic modeling of quinoline HDN over two supported NiMoS2 catalysts. Effects of support acidity on the activity and the selectivity on quinoline HDN. Competitive adsorption of nitrogen compounds is stronger over NiMo(P)/ASA than over NiMo(P)/Al2O3. Acidity of the support modifies the electronic properties of sulfide phase.
