    • A solid product resulting from the nucleated growth of the product on solid material of either the same or different composition and having a density higher than the reaction medium is formed from one or more liquid phase reactants by a method which comprises tangentially introducing the liquid phase reaction medium into the lower, smaller end of an inverted, frusto-conical reactor-separator, thereby imparting an upward swirling motion to the reaction medium in the reactor-separator, the horizontal velocity at the bottom of the reactor-separator being sufficiently large to cause fluidization of larger, solid product particles and concentration of them in the central lower portion of the reactor-separator and the vertical velocity at the top of the reactor-separator being sufficiently small to avoid carry-over of the smaller solid particles but sufficiently large to concentrate them in the upper portion of the reactor-separator; at least periodically recovering the larger, solid product particles in spherical form from the bottom of the reactor-separator; and recovering fluid products from the top of the reactor-separator. The method described is useful in a variety of reactions wherein a solid product forms by a nucleated growth mechanism. Examples of such reactions include thermal upgrading of petroleum derived feedstocks and coal liquids, synthesis of zeolites and Ziegler-Natta polymerization of olefins.
    • 由相同或不同组成的固体材料产生的具有比反应介质高的密度产生的固体产物由一种或多种液相反应物形成,该方法包括切向引入液相反应 介质进入倒立的截头圆锥形反应器分离器的较小的较小端,从而向反应器分离器中的反应介质施加向上旋转运动,反应器分离器底部的水平速度足够大以致 更大的固体产物颗粒的流化和它们在反应器分离器的中心下部的浓度以及反应器分离器顶部的垂直速度足够小以避免较小固体颗粒的滞留,但足够大以至 将它们集中在反应器分离器的上部; 从反应器分离器的底部至少周期性地回收球形的更大的固体产物颗粒; 并从反应器分离器的顶部回收流体产物。 所描述的方法可用于通过有核生长机制形成固体产物的各种反应。 这种反应的实例包括石油衍生的原料和煤液体的热升级,沸石的合成和烯烃的齐格勒 - 纳塔聚合。
