Effects of Phosphorous Promoter on Catalytic Performance for Oligomerization of Butene over Ni-based Catalysts

摘要

In dimerizing n-butenes to mixed octenes, mixed dodecenes (C_(12) Olefins) are produced simultaneously as a result of side reaction, trimerization. The industrial needs for mixed dodecenes are very small compared to that of mixed octenes. For the production of raw materials such as plasticizers, it is highly desirable to find a method which enhances dimmer's selectivity and yield(1-7). The effects of phosphorous over Ni-based catalyst on C_8 yield and selectivity in dimerization reaction were investigated. The effects of 1,3-butadiene in butenes on catalyst life for oimerization were also tested.
