摘要: Abstract The catalytic oxidation properties of HY, HZSM5 and HZSM11 zeolites modified by vanadium–phosphorus oxide or vanadium–oxide deposition catalysts obtained from V–silicalite precursors are analyzed in the selective conversion butadiene to furan maleic anhydride para–and meta–xylene ammoxidation, pure ZSM5 with different Si/Al ratios tested propane aromatics presence O 2 . In HY deposited PV clusters interact protondonor centers giving rise an inhibition formation butadiene. This effect is not present zeolite. An analogous change behavior found for ammoxidation xylenes. insertion V framework silicalite leads to, after activation, sites synthesis Selectivity increases Si/V atomic ratio. oxygen feed on zeolites. a function concentration OH attributed radical–like surface sites.
