STUDY OF PROPYLENE CATALYTIC OXIDATION PROCESS IN A FLOW-TYPE TUBULAR REACTOR

The effect of partial pressure and contact time on the oxidation process of propylene in zinc-vanadium oxide catalyst samples was studied in a flow-type tubular reactor and the optimal conditions were determined. It was shown that propylene oxidation products in the taken catalyst samples consist of acetic acid, carbon dioxide, acetone and acetaldehyde. Based on the obtained results, the effect of partial pressure of propylene, oxygen, water vapor and contact time on the oxidation process of propylene was studied in order to determine the optimal oxidation conditions of propylene in the indicated catalyst. The oxidation of olefins in the liquid and gas phase is based on obtaining a number of target and intermediate products with the participation of various binary catalysts. The oxidation of propylene, which is an example of olefins, in the liquid phase involves the oxidation of titanium and its alloys with molecular oxygen on the contact surfaces of this catalyst. The highest form of oxidation of olefins in the gas phase is catalyst indicates molybdenum, cobalt, iron, bismuth, antimony and silicon oxides. One of the catalytic oxidation products of propylene is acetic acid
