    • An ammoxidation reactor includes an outer ring of sets of multistage cyclones suspended in the reactor. Each multistage set of cyclones includes a first stage cyclone having a first stage inlet configured to receive a reactor stream flowing up from a fluidized catalyst bed in the reactor and separate at least a portion of catalyst from the reactor stream. A ratio of square meter of first stage inlet area per square meter of available cross sectional area of the reactor is about 0.03 to about 0.05. An ammoxidation process includes reacting a hydrocarbon stream in a fluidized catalyst bed in a reactor to produce a reactor stream. The process further includes separating catalyst from the reactor stream in an outer ring of sets of multistage cyclones, each multistage set of cyclones including a first stage cyclone having a first stage inlet configured to receive a reactor stream flowing up from a fluidized catalyst bed in the reactor and separate at least a portion of catalyst from the reactor stream. A ratio of cyclone inlet velocity in meters/second to a reactor effluent velocity in meters/second is 15 or greater.
    • 氨氧化反应器包括悬浮在反应器中的一组多级旋风分离器的外圈。 每个多级旋风分离器包括第一级旋风分离器,其具有构造成接收从反应器中的流化催化剂床向上流动的反应器流的第一级入口,并将至少一部分催化剂与反应器流分离。 反应器每平方米可用横截面积的一级入口面积的平方米的比例约为0.03至约0.05。 氨氧化方法包括使烃流在反应器中的流化催化剂床中反应以产生反应器流。 该方法还包括在一组多级旋风分离器的外圈中将催化剂与反应器物流分离,每个多级旋风分离器包括第一级旋风分离器,该第一级旋风分离器具有第一级入口,该第一级入口配置成接收从流化催化剂床流出的反应器流 并将至少一部分催化剂与反应器流分离。 旋风进口速度(米/秒)与反应器流出速度(米/秒)的比例为15或更大。
