超重力旋转滴流床反应器液膜调控强化加氢催化反应机制研究

滴流床反应器广泛应用于气液固多相加氢催化反应，反应器内液膜厚度、更新速率等流体力学参数是影响界面传递与反应的关键之一。但在常规重力场下，滴流床反应器自身难以实现对液膜流体力学行为的有效调控。本项目创新性地提出新一代超重力旋转滴流床反应器调控液膜从而强化多相催化反应过程的新思想，围绕超重力旋转滴流床反应器液膜调控强化加氢催化反应及选择性机制的关键科学问题，研制适配超重力环境的整体式催化功能填料，创制新结构超重力旋转滴流床反应器，研究超重力环境下液膜的流体力学行为和调控方法，揭示超重力旋转滴流床反应器强化催化反应及选择性的机制，为高效超重力旋转滴流床催化反应器的开发奠定科学基础。

Trickle bed reactors are widely used in gas-liquid-solid catalytic hydrogenation reactions. Liquid film parameters, such as thickness, renewal rate, play an important role on the mass transfer and reaction rate. But the trickle bed reactor itself is difficult to effectively adjust the liquid film’s hydrodynamics. The proposal gives a novel idea of inventing a rotating trickle bed reactor (RTBR) to intensify the catalytic hydrogenation reaction processes. Based on the idea of adjusting the liquid film’s hydrodynamics by the centrifugal force in the RTBR to intensify the hydrogenation reaction, we firstly prepare a monolithic catalyst and then design and fabricate a RTBR. Experiments of liquid film’s hydrodynamics will be conducted and mechanism of catalytic reaction process intensification and selectivity enhancement will be analyzed, which provides scientific basis for the development of a Higee catalytic reactor with high efficiency.
