    • A process for preparing alpha-olefins is provided which comprises:(a) converting a feed containing one or more lower olefins in the presence of a medium pore crystalline silicate zeolite catalyst under reaction conditions providing a mixture of higher olefinic products;(b) contacting at least a part of the mixture of higher olefinic products resulting from step (a) with an alpha-olefin in the presence of a metathesis catalyst under olefin metathesis conditions to provide a mixture of alpha-olefins having a different carbon number than the feed olefin;(c) separating the alpha-olefin product of step (b) into at least two fractions, one fraction containing predominantly lower alpha-olefin hydrocarbons and the other fraction containing predominantly higher alpha-olefin hydrocarbons; and,(d) recycling at least a part of the lower alpha-olefin hydrocarbon fraction resulting from step (c) as feed for step (a).
    • 提供一种制备α-烯烃的方法,其包括:(a)在提供高级烯烃产物的混合物的反应条件下,在中孔结晶硅酸盐沸石催化剂存在下,将含有一种或多种低级烯烃的进料转化; (b)在复分解催化剂存在下,在烯烃复分解条件下使步骤(a)得到的较高级烯烃产物的至少一部分混合物与α-烯烃接触,以提供具有不同碳数的α-烯烃的混合物 比进料烯烃; (c)将步骤(b)的α-烯烃产物分离成至少两个馏分,一个馏分含有主要较低的α-烯烃烃,另一部分含有主要高含量的α-烯烃; 和(d)将步骤(c)得到的低级α-烯烃烃级分的至少一部分再循环作为步骤(a)的进料。
