概述/General Introduction

固定床反應(yīng)器裝填有固體催化劑或固體反應(yīng)物用以實現(xiàn)多相反應(yīng)過程的一種反應(yīng)器。固體物通常呈顆粒狀，粒徑2～15mm左右，堆積成一定高度（或厚度）的床層。床層靜止不動，流體通過床層進(jìn)行反應(yīng)。

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.

流化床反應(yīng)器是一種利用氣體或液體通過顆粒狀固體層而使固體顆粒處于懸浮運動狀態(tài)，并進(jìn)行氣固相反應(yīng)過程或液固相反應(yīng)過程的反應(yīng)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 .
