Beschreibung
Zusammenfassung:	A preparation method of a butylene oxidative dehydrogenation catalyst is characterized in that the catalyst is prepared through a two-step gel formation and coprecipitation technology, and the method comprises the following steps: 1, adding ammonia water to an aqueous solution containing Fe, Zn and Ca series elements in a dropwise manner to control the pH value of a system to 7.0-8.0; and 2, stopping dropwise addition of the ammonia water, continuously introducing CO2 for 0.5-2h, keeping the pH value of the system unchanged, adding Sesbaria cannabina powder, mixing to obtain a precipitate, ageing the precipitate, washing the aged precipitate, drying the washed precipitate, and roasting the dried precipitate to obtain the butylene oxidative dehydrogenation catalyst.
