    • A process for producing ethylene from ethanol combining the catalytic conversion of hydrocarbons: an ethanol feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, and a coked catalyst and an target product of ethylene are obtained after separating the reaction stream; a hydrocarbon feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, a spent catalyst and an oil vapor are obtained after separating the reaction stream, and the oil vapor is further separated to give the products such as gas, gasoline and the like; a part or all of the coked catalyst and a part or all of the spent catalyst enter the regenerator for the coke-burning regeneration, and the regenerated catalyst is divided into two portions, wherein one portion returns to be contacted with the hydrocarbon feedstock, and the other portion, after cooling, returns to be contacted with ethanol feedstock. This process not only reasonably utilizes the excessive thermal energy of the hydrocarbon conversion, but also solves the problem of heat supply for the conversion of ethanol, thus ensuring the continuous catalytic conversion of ethanol and generating enormous economic benefits. For the catalytic conversion of the ethanol, the content of ethylene is 95 vol% or more in the gas product; and the conversion of ethylene is not less than 99%. For the catalytic conversion of the hydrocarbons, the yield for the light olefins increases slightly by at least 2 mol%.
    • 一种用于从乙醇组合烃的催化转化生产乙烯的方法:乙醇原料与Y型沸石含催化剂,得到的产物料流,和结焦的催化剂与乙烯的目标产物分离反应流之后获得接触; 的烃原料与Y型沸石含催化剂,得到的产物料流,废催化剂和油蒸汽被分离反应流之后获得接触,和油蒸汽被进一步分离,得到产品:如天然气,汽油和 等; 的一部分或全部的结焦催化剂和部分或全部的废催化剂进入用于烧焦的再生的再生器,和再生的催化剂分成两个部分,worin一个部分返回到与所述烃原料接触,并 另一部分,冷却后,返回到与乙醇原料接触。 这个过程不仅合理利用烃转化的过量的热能,因此解决了但热供应用于乙醇转化的麻烦,从而确保了乙醇的连续催化转化并产生巨大的经济效益。 对于乙醇的催化转化中,乙烯的含量是在气体产品95体积%以上; 和乙烯的转化率不小于99%。 用于烃的催化转化,产量为轻质烯烃稍微增加至少2摩尔%。
