Abstract:
The conversion(dehydration/dehydrogenation) of 2-propanol and methanol over M0.05Al0.95PO4 (M=V, Cr, Mn, Fe, Co, or Ni) catalysts were studied at different temperatures and flow rates in a fixed bed catalytic reactor. The activation and kinetic parameters were calculated using Arrhenius and frying equations. Among all the samples VOAlPO4 showed highest conversion and selectivity towards olefin formation. Selectivity studies indicated that 2-propanol and methanol dehydration followed a combination of parallel and consecutive pathways while surface poisoning studies suggested that mostly Bronsted acid sites participated in the dehydration as well as cracking reactions.
