    • A process includes periodically or continuously introducing an olefin monomer and periodically or continuously introducing a catalyst system or catalyst system components into a reaction mixture within a reaction system, oligomerizing the olefin monomer within the reaction mixture to form an oligomer product, and periodically or continuously discharging a reaction system effluent comprising the oligomer product from the reaction system. The reaction system includes a total reaction mixture volume and a heat exchanged portion of the reaction system comprising a heat exchanged reaction mixture volume and a total heat exchanged surface area providing indirect contact between the reaction mixture and a heat exchange medium. A ratio of the total heat exchanged surface area to the total reaction mixture volume within the reaction system is in a range from 0.75 in-1 to 5 in-1, and an oligomer product discharge rate from the reaction system is between 1.0 (lb)(hr-1)(gal-1) to 6.0 (lb)(hr-1)(gal-1).
    • 一种方法包括周期性地或连续地引入烯烃单体,并周期性地或连续地将催化剂体系或催化剂体系组分引入反应体系内的反应混合物中,使烯烃单体在反应混合物中低聚以形成低聚物产物,并且周期性地或连续地 包含来自反应体系的低聚物产物的反应系统流出物。 反应体系包括总反应混合物体积和反应体系的热交换部分,其包含热交换反应混合物体积和提供反应混合物与热交换介质间接接触的总热交换表面积。 反应体系内总热交换表面积与总反应混合物体积之比在0.75-1.5英寸-1的范围内,并且来自反应体系的低聚物产物排出速率在1.0(磅) (hr-1)(gal-1)至6.0(lb)(hr-1)(gal-1)。
