费托产物中α-烯烃与烷烃分离技术及应用

Separation Technology and Application of α-Olefin and Alkane in Fischer-Tropsch Products

烯烃作为石化行业一类重要原料,已广泛应用于生产共聚单体、聚α-烯烃(PAO)基础油、高碳醇、(重)烷基苯及α-烯烃磺酸盐等领域。高温费托合成产物中拥有高含量且连续分布的α-烯烃和烷烃,因此分离相同碳数α-烯烃与烷烃工艺技术成为提高费托产物高附加值的关键。

As an important raw material for the petrochemical industry,α-olefin has been widely used in the production of comonomers,poly-α-olefin(PAO)base oils,higher alcohols,(heavy)alkylbenzenes,andα-olefin sulfonates.High-temperature Fischer-Tropsch synthesis products have a high content and continuous distribution ofα-olefins and alkanes,so the separation ofα-olefins and alkanes with the same carbon number process technology becomes the key to increase the high added value of FischerTropsch products.
