摘要
Abstract
The effects of superficial gas velocity
catalyst loading
liquid properties and internal fitting on gas holdup of air/water
air/paraffin oil and air/catalyst/paraffin oil were investigated in a 0 2 m diameter
4 2 m height slurry bubble column reactor operating with methanol synthesis copper-based catalyst and methanol dehydration catalyst. The experimental data showed that gas holdup increased with superficial gas velocity no matter whether there was a heat exchanger. However
no matter whether there was a heat exchanger
gas holdup decreased with the increase of catalyst loading. The existence of heat exchanger favored the increase of gas holdup. The gas holdup in the air-water system was slightly higher than in the air-paraffin system. Empirical correlations for gas holdup data were proposed.
