Beschreibung
Zusammenfassung:	The invention relates to a selective oxidation method of light olefins. According to the selective oxidation method, reaction raw materials propylene, water, and air are subjected to preheating using a preheater at a temperature higher than 120 DEG C, and then are delivered into a fixed bed single pipe reactor; and salt bath heating is carried out. The fixed bed single pipe reactor is filled with a propylene selective oxidation catalyst; the selective oxidation catalyst contains molybdenum, bismuth, iron, nickel, cobalt, and tungsten, and also contains magnesium-based lanthanum hexaaluminate. Structure of the selective oxidation catalyst is stable; loss of the active ingredients, such as molybdenum, is not easily caused; phase transformation of the active phases is not easily caused; and selectivity and yield of target products are improved.
