Slurry bubble column reactor (SBCR) is the preferred choice of reactor for Fischer – Tropsch (FT) synthesis. However, the understanding of the catalyst flow dynamics in FT-SBCR is still lacking. In this work, hydrodynamics of the FT catalyst were studied using computer aided radioactive particle tracking (CARPT) technique at the mimicked conditions of FT synthesis for the first time. Solids ensemble averaged velocity, turbulent kinetic energy, Reynolds normal and shear stresses were experimentally obtained. Effect of operating conditions on the velocity flow field were investigated. Further, studies were conducted to quantify the difference in flow field due to the change in the liquid and solid phases. It was found that the change of solids turbulence is insignificant with pressure and solids loading at the studied operating conditions. Further, it was found that the surface tension of the fluid and the solid properties plays a dominant role on the turbulence.

淤浆鼓泡塔反应器（SBCR）是费-托合成（FT）合成反应器的首选。然而，仍然缺乏对FT-SBCR中催化剂流动动力学的理解。在这项工作中，首次在模拟的FT合成条件下，使用计算机辅助放射性粒子跟踪（CARPT）技术研究了FT催化剂的流体动力学。实验获得了固体集合平均速度，湍动能，雷诺法向和切应力。研究了工作条件对速度流场的影响。此外，进行了研究以量化由于液相和固相变化而引起的流场差异。发现在所研究的操作条件下，固体湍流的变化与压力和固体负载无关紧要。更多，
