A process for oligomerising alkenes having from 3 to 6 carbon atoms which comprises contacting a feedstock comprising a) one or several alkenes having x carbon atoms, and, b) optionally, one or several alkenes having y carbon atoms, x and y being different, with a catalyst containing a zeolite of the MFS structure type, under conditions to obtain selectively oligomeric product containing predominant amounts of certain oligomers. The process is carried out at a temperature comprised between 125 and 175° C. when the feedstock contains only alkenes with 3 carbon atoms and between 140 and 240° C., preferably between 140 and 200° C. when the feedstock contains comprises at least one alkene with 4 or more carbon atoms.
一种用于寡聚烯烃的方法,其含有从3到6个碳原子的烯烃,包括将含有a)一个或多个具有x个碳原子的烯烃,以及b)可选地,一个或多个具有y个碳原子的烯烃,其中x和y不同,与含有MFS结构类型沸石的催化剂接触,在条件下,以选择性地获得含有主要某些寡聚体的寡聚产物。当原料只含有3个碳原子的烯烃时,该过程在温度为125至175°C之间进行;当原料含有至少一种含有4个或更多碳原子的烯烃时,该过程在温度为140至240°C之间进行,优选在140至200°C之间进行。
