Ammonium salts,(NH4)6HPMo11MO40(M = Ni,Co,Fe),have been investigated for the oxidation of propane,with molecular oxygen,at temperature ranging between 380 ℃ and 420 ℃ after insitu pretreatment performed at two heating rate of 5 or 9 ℃/min.They were characterized by BET method,XRD,31P NMR,UV-Vis and IR techniques.The catalysts were found active in the propane oxidation and selective to propene or acrolein,in particular for samples pre-treated with the heating rate of 9 ℃/min.
Ammonium salts, (NH4) 6HPMo11MO40 (M = Ni, Co, Fe), have been investigated for the oxidation of propane, with molecular oxygen, at temperature ranging between 380 ° C and 420 ° C after insitu pretreatment performed at two heating rates of 5 or 9 ° C / min. They were characterized by BET method, XRD, 31P NMR, UV-Vis and IR techniques. The catalysts were found active in the propane oxidation and selective to propene or acrolein, in particular for samples pre-treated with the heating rate of 9 ° C / min.
