Gas - Liquid mass Transfer in a Slurry Bubble Column Reactor under High temperature and High Pressure

摘要

The gas-liquid mass transfer of H_2 and CO in a high temperature and high-pressure three-phase slurry bubble column reactor is studied. The gas-liquid volumetric mass transfer coefficients k_L a are obtained by measuring the dissolution rate of H_2 and CO. The influences of the main operation conditions, such as temperature, pressure, superficial gas velocity and solid concentration, are studied systematically.
