固定（流化）床反應器 Fixed bed reactor-菲立化學工程（上海）有限公司

概述/General Introduction

固定床反應器裝填有固體催化劑或固體反應物用以實現多相反應過程的一種反應器。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，流體通過床層進行反應。

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，并進行氣固相反應過程或液固相反應過程的反應器。

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 .
