摘要: 通过对FX-01沸石催化剂上苯与丙烯的烷基化反应中试工况进行模拟,判识了合适的外扩散传质关联式,并计算出外扩散传质阻力,得出了反应过程的控制步骤。固定床鼓泡反应器中烷基化反应过程阻力的大小顺序为:气液膜阻力>液固膜阻力>内扩散阻力与化学反应阻力之和。

Abstract: By simulating the pilot plant of the alkylation of benzene with propylene over β zeolite in a fixed bubble reactor, the suitable external mass transfer correlation equations from literature were chosed to calculate coefficients and external mass transfer resistance. The resistance values of alkylation process are in the following order: gas - liquid film > liquid - solid film > internal diffusion and reaction.
