摘要

Abstract

The understanding of the gas-liquid flow characteristics in a micro-packed bed reactor is still immature

especially for many gas-organic working systems commonly used in industry. Accordingly

this study proposes a platform to investigate the gas-liquid flow characteristics in a micro-packed bed reactor and presents a unified expression for these characteristics of both organic and aqueous liquid phase. The influence of two-phase flow rate

working solution viscosity

and packing particle size on the liquid holdup and pressure drop were studied. The gas-organic working systems results show that the liquid holdup ranges between 0.5 and 0.8 and pressure drop ranges from 50 to 350 kPa·m

-1

. In particular

a strong correlation between the two flow characteristics parameters (liquid holdup and pressure drop) was proposed for the first time. Finally

a general pressure drop mathematical prediction model in micro-packed bed were developed.
