    • A novel liquid phase polymerization process for preparing a polyolefin product having preselected properties is disclosed. The process includes the steps of providing a liquid feedstock which contains an olefinic component and a catalyst composition consisting of a stable complex of BF3 and a complexing agent therefor. The feedstock may comprise any one or more of a number of olefins including branched olefins such as isobutylene, C3 to C15 linear alpha olefins and C4 to C15 reactive non-alpha olefins. The feedstock and the catalyst composition are introduced into a residual reaction mixture recirculating in a loop reactor reaction zone provided in the tube side of a shell and tube heat exchanger at a recirculation rate sufficient to cause intimate intermixing of the residual reaction mixture, the added feedstock and the added catalyst composition. The heat of the polymerization reaction is removed from the recirculating intimately intermixed reaction admixture at a rate calculated to provide a substantially constant reaction temperature therein while the same is recirculating in said reaction zone. The conditions in the reactor are appropriate for causing olefinic components introduced in said feedstock to undergo polymerization to form the desired polyolefin product in the presence of the catalyst composition. A product stream containing the desired polyolefin product is withdrawn from the reaction zone. The introduction of the feedstock into the reaction zone and the withdrawal of the product stream from the reaction zone are controlled such that the residence time of the olefinic components undergoing polymerization in the reaction zone is appropriate for production of the desired polyolefin product.
    • 公开了一种用于制备具有预选性质的聚烯烃产品的新型液相聚合方法。 该方法包括提供含有烯烃组分的液体原料和由稳定的BF 3络合物及其络合剂组成的催化剂组合物的步骤。 原料可以包括许多烯烃中的一种或多种,​​包括支链烯烃如异丁烯,C 3 -C 15直链α-烯烃和C 4 -C 15反应性非α-烯烃。 将原料和催化剂组合物引入到在壳管式热交换器的管侧中设置的环管反应器反应区中再循环的残留反应混合物,其循环速率足以引起残余反应混合物的密集混合,加入的原料 和添加的催化剂组合物。 将聚合反应的热量从循环的紧密混合的反应混合物中除去,其速率被计算为在其中提供基本上恒定的反应温度,同时在该反应区中再循环。 反应器中的条件适合于在催化剂组合物存在下使引入所述原料的烯烃成分进行聚合以形成所需的聚烯烃产物。 从反应区取出含有所需聚烯烃产物的产品流。 控制将原料引入反应区和从反应区中引出产物流,使得在反应区中进行聚合的烯烃组分的停留时间适于生产所需的聚烯烃产物。

    • Apparatus for olefin polymerization includes a plurality of shell and tube olefin polymerization reactors, each of which has an olefin polymerization reaction mixture inlet connection and a crude polyolefin product outlet connection. Each reactor is equipped with a recirculation system including a pump arranged to circulate a reaction mixture through the tube side of the reactor independently of the introduction of olefin polymerization reaction mixture into the reactor. The apparatus also includes an inlet reaction mixture distribution manifold and an outlet polymerization reaction mixture collection manifold interconnecting the reactors for operation in parallel. The apparatus also includes catalyst composition and catalyst modifier inlets for each reactor arranged such that a catalyst modifier to may be introduced into each reactor at a rate which is independent of the introduction of catalyst composition. The apparatus further incorporates a crude polyolefin product catalyst removal and wash system including a plurality of settler vessels, associated piping and an inlet for a catalyst killing agent. This crude polyolefin product catalyst removal and wash system operates to receive crude polyolefin product from the crude polyolefin product outlet and remove residual catalyst therefrom.
