摘要：
A method for improving the light olefin yield in the process of preparation of a light olefin using an oxygen-containing compound, more specifically, in which, a multi-stage dense phase fluidized bed comprising k secondary pre-carbon deposition zones (k≧1) and n secondary reaction zones (n≧1) is used as a reactor, and a multi-stage dense phase fluidized bed regenerator comprising in secondary regeneration zones (m≧2) is used as a main equipment, and by re-refining hydrocarbons with four or more carbons obtained in the separation section, or adding naphtha, gasoline, condensate oil, light diesel oil, hydrogenation tail oil or kerosene in the reaction zone, the method primarily solves the problems in the prior art of the uniformity of carbon deposition amount and the carbon content of the catalyst being difficult to control, and the light olefin yield being low.
摘要（中）：
一种在使用含氧化合物制备轻质烯烃的方法中提高轻烯烃产率的方法，更具体地说，其中包括k级第二预碳沉积区（k≥1）的多阶段致密相流化床 ）和n个次级反应区（n≥1）用作反应器，并且将包含在次级再生区（m≥2）中的多级密相流化床再生器用作主要设备，并且通过重新精炼碳氢化合物 在分离段中获得四个或更多个碳，或在反应区中加入石脑油，汽油，冷凝油，轻质柴油，氢化尾油或煤油，该方法主要解决了现有技术中碳沉积均匀性的问题 量和催化剂的碳含量难以控制，轻烯烃产率低。
