固定（流化）床反应器

　　固定床反应器装填有固体催化剂或固体反应物用以实现多相反应过程的一种反应器。固体物通常呈颗粒状，粒径2～15mm左右，堆积成一定高度（或厚度）的床层。床层静止不动，流体通过床层进行反应。

　　The fixed bed reactor is a reactor filled with a solid catalyst or a solid reactant foe the realization heterogeneous reaction. Solid matter is usually granular granular particle size of about 2-15mm ,stacked into a certain height on the bed .the bed is stationary and the liquid reacts through the bed.

　　流化床反应器是一种利用气体或液体通过颗粒状固体层而使固体颗粒处于悬浮运动状态，并进行气固相反应过程或液固相反应过程的反应器。

　　The fluidized bed reactor is a reactor in which the solid particles are in a suspended state by means of a gas or a liquid through a solid layer and subjected to a gas-solid or liquid-solid reaction .
