摘　　要：气液及气液固三相浆态鼓泡塔的气相轴向返混系数宋同贵，赵玉龙，苏晓丽，张碧江（中国科学院山西煤炭化学研究所，煤转化国家重点实验室，太原０３０００１）关键词：气液鼓泡塔，浆态鼓泡塔，气相轴向返混１前言在鼓泡塔反应器的设计、放大及数学模拟中，气相轴向返混系...Gas phase axial dispersion coenicients in a bubble column slurry reactor(BCSR)have beenmeasured in the range of column diameter 10,20 cm;gas velocity 2～20 cm/s;solid concen-tration 5%～20%and particle size 53 μm,by measuring RTD of gas tracer H_2 and the methodof curve fitting in the time-domain.Acorrelation of E_g in the case of water as liquid medium ispresented as follows:E_g=18.68 U_gD￣(1.44) (gas-liquid)E_g=104. 91 U_gD￣(1.44)C_(gas-liquid-solid)From comparison of E_g got from paraffin liquid as liquid medium with that of water,it can befound that the effects of both U_gand c_gon E_g decrease significantly and a correlation equation ofE_g was not obtained.
