Abstract

Abstract Catalytic oxidation of propane was studied over metal phosphates using propane rich feed. Oxidation reached measurable rate at 620–700 K over the catalysts. Over Cu2P2O7, Ni2P2O7, and LaPO4, propene, acetaldehyde, and methanol were principal products and the sum of these selectivities reached 70–80 mol%. Maximum selectivity of acrolein, 11.5 mol%, was observed over Mn2P2O7. Selectivity of propene reached 50.7 mol% over Co2P2O7. Deep oxidation was dominant over Cr4(P2O7)3, (ZrO)2P2O7, and CePO4.
