Catalytic decomposition of ethanol on V2O5/AIPO(4) catalysts

Different ratios of vanadium pentoside supported on aluminum phosphate (1-3 0 mol%) have been prepared by an impregnation method. The original and calc ined samples were characterized by TG, DTG, DSC, X-ray diffraction, IR spec tra, hi adsorption and electrical conductivity measurements. The catalytic decomposition of ethanol has been carried out at 210 degrees C in a flow sy stem at 1 atm using air as a carrier gas. The results indicate that the cat alysts calcined at 400 degrees C were active and selective towards ethene f ormation whereas the samples calcined at 600 degrees C showed a drastic red uction in both activity and selectivity.
