摘要 在1立升的高压机械搅拌釜中,采用气体间歇吸收技术,在80~160℃,0.5~5MPa的范围内,测定了氢气和一氧化碳在混二甲苯中的溶解度。氢气和一氧化碳的溶解度随着温度和压力的增加而变大,且在相同的温度和压力下,一氧化碳的溶解度大于氢气的溶解度。与它们在间二甲苯中的溶解度相比,在混二甲苯中的溶解度是较小的.此外,使用正规溶液理论的Prausnitz-Shair方法对它们的溶解度进行了估算。可以看出,一氧化碳在二甲苯中的溶解度的估算值与实验结果较相符。氢气由于临界温度较低,没有合适的估算式,故用实验回归的公式结合Prausnitz-Shair方法中的其它公式进行估算,估算值与实验值大体相符。 The equilibrium solubility of the hydrogen and the carbon monoxide in mixed xylene was measured as functions of temperature (353K^433K) and pressure(l^5MPa) in a 1 liter mechanically agitated autoclave. The solubility of carbon monoxide and hydrogen in the mixed xylene were estimated by using the Prausnitz-Shair method. In the range of operating conditions investigated, the solubility values for the hydrogen and the carbon monoxide in the mixed xylene increased with the pressure and the temperature.
