The influence of the reaction mixture feed rate in a tubular turbulent apparatus with a diffuser–confuser design and its geometric parameters on the fields of turbulent kinetic energy and its dissipation rate has been shown as a result of the physicochemical fluid dynamics modeling of the reaction mixture flow through an apparatus. The reaction mixture consists of toluene, butadiene and particles of the active sediment of TiCl4–Al(i-C4H9)3 catalytic system. It was shown that an increase in the values of the fields of turbulent kinetic energy and its dissipation rate leads to an increase in the degree of dispersion and specific surface area of the catalytically active sediment particles and to an increase of TiCl4–Al(i-C4H9)3 catalytic system activity in the process of obtaining low-molar-mass polybutadiene—a polymer component of sticky glue.

在生产低摩尔质量聚丁二烯(一种粘胶成分)过程中通过改变其分散组成来控制 TiCl4–Al(i-C4H9)3 催化体系颗粒的活性

反应混合物的物理化学流体动力学建模结果表明,在具有扩散器-干扰器设计的管状湍流装置中反应混合物进料速率及其几何参数对湍流动能场及其耗散率的影响已被证明流过一个装置。反应混合物由甲苯、丁二烯和 TiCl4–Al(i-C4H9)3 催化体系的活性沉积物颗粒组成。结果表明,湍动能场值及其耗散率的增加导致催化活性沉积颗粒的分散程度和比表面积的增加以及TiCl4-Al(i- C4H9)3 催化体系在获得低摩尔质量聚丁二烯——粘性胶的聚合物组分的过程中的活性。
