Abstract
Increase in catalytic activity performance of a stoichiometric NiMoO4 system has been studied using a periodic flow reactor system. Aging results in an increase of selectivity, a decrease in BET surface area, a weak decrease in activity and a change in surface morphological properties. alpha-Nickel molybdate exposed to the reaction gases and temperature tends to transform progressively toward an alpha-aged phase more and more like to the most selective beta-phase.File in questo prodotto:
