煤液化催化剂多级逆流浆态反应器流体分布与传质研究

以煤为载体的煤直接液化高效催化剂的制备需要在湍动剧烈的环境中分散和合成,气液固三相反应器的设计是其核心技术。主要从反应器的设计要求、气相含率及体系氧传质系数来研究此反应器的流体力学与传质特性。此反应器能满足催化剂制备时的要求,而且可以大幅度的减少气液相的传质阻力的影响。 The preparation of the coal direct liquefaction catalyst need make the material in the highly dispersion state and promote the chemical reaction,so g-l-s three phrase reactor is a main technical equipment.In this paper,the fluid mechanics and mass transfer character of the reactor has been researched on the follows the design requirements,air content and oxygen transfer efficiency.The reactor can meet the preparation of catalyst,the influence of the gas-liquid phrase mass transfer resistance can be reduced
