本文采用气体间歇物理吸收技术，在一立升的表面进气式高压机械搅拌釜中，在温度（３７３～５７３Ｋ）、气体压力（１～４ＭＰａ）和混合速度（１３．３Ｈｚ）的实验条件下，测定了Ｈ２、ＣＯ在液体石蜡、正二十八烷烃、ＦＴ３００蜡中的体积传质系数（ｋＬａ），实验中发现：两种气体在三种液体介质中的体积传质系数均随温度的升高而增加，随气体分压的增加而增加。在同一种液体介质中，Ｈ２和ＣＯ的体积传质系数具有相同的数量级。两种气体的体积传质系数随液体分子量的增加而降低。并对Ｈ２液体石蜡体系，考察了不同的混合速度（６．７～２０．０Ｈｚ）、液体体积和固体颗粒浓度（０～１５Ｗ％）对气体的体积传质系数的影响，实验结果表明：氢气的体积传质系数随混合速度的增加而增加，随液体体积的增加而降低，在颗粒浓度较低的情况下，氢气的体积传质系数高于不含颗粒时的ｋＬａ值，但当颗粒浓度进一步增加时，体积传质系数呈下降趋势。
In this paper, the gas intermittent physical absorption technique was used in the experiments of a rising surface air inlet high-pressure mechanical stirred tank under the experimental conditions of temperature (373 ~ 573K), gas pressure (1 ~ 4MPa) and mixing speed (13.3Hz) , The mass transfer coefficient (kLa) of H2 and CO in liquid paraffin, n-octacosane and FT300 wax was measured. It was found in the experiment that the volumetric mass transfer coefficients of both gases in the three liquid mediums varied with the temperature Increase with increasing gas partial pressure increases. In the same liquid medium, the volumetric mass transfer coefficients of H2 and CO are of the same order of magnitude. Volumetric mass transfer coefficients of both gases decrease with increasing liquid molecular weight. The effects of different mixing velocity (6.7 ~ 20.0Hz), liquid volume and solid particle concentration (0 ~ 15W%) on the volumetric mass transfer coefficient of gas were investigated for H2 liquid paraffin system. The experimental results show that hydrogen The volumetric mass transfer coefficient increases with the increase of mixing velocity and decreases with the increase of liquid volume. At lower particle concentration, the mass transfer coefficient of hydrogen is higher than that without particles, but when the particle concentration With further increase, the volumetric mass transfer coefficient shows a downward trend.
