前言用悬浮有很小粒状催化剂的鼓泡反应器进行某些类型的氢化反应。在一定条件下,反应器的效能取决于催化剂的活性,但是也会明显地受到各个相界面上传质的影响。连续过程的各步骤的速率可以由下列方程确定: 气液界面上氢气转移速率: r=k_La(C~+-C_L) ①液相一催化剂界面上的氢传递速率: r=mk_sa_s(C_L-C_s) ②和表
Preface Certain types of hydrogenation reactions are carried out with bubbling reactors suspended with small particulate catalysts. Under certain conditions, the efficiency of the reactor depends on the activity of the catalyst, but it is also significantly affected by the mass transfer at the interface of each phase. The rate of each step of the continuous process can be determined by the following equation: Hydrogen transfer rate at gas-liquid interface: r = k_La (C ~ + -C_L) (1) Hydrogen transfer rate at the liquid-catalyst interface r = mk_sa_s (C_L-C_s ) ② and table
