氢气和一氧化碳在混合辛烯中溶解度的测定

Solubility determination of hydrogen and carbon monoxide in mixed octene

采用高压反应釜,在温度为343～380 K,压力为2～5 MPa的条件下,测定了氢气(H2)和一氧化碳(CO)在混合辛烯中的溶解度,并采用正规溶液理论中的Prausnitz-Shair方法得出相应的计算值。结果表明,H2和CO在混合辛烯中的溶解度随着压力或温度的升高而增大,且在相同的温度和压力下,CO在混合辛烯中的溶解度大于H2的溶解度;H2,CO溶解度计算值与实验值最大相对误差分别为11.3%,6.6%。

The equilibrium solubility of H2 and CO in mixed octene were measured in a mechanically agitated autoclave within the range of 343 - 380 K and 2 -5 MPa, and also estimated by using the Prausnitz - Shair method. The results showed that H2 and CO solubilities in mixed oetene increased with the temperature and the pressure rising, and at the same temperature and pressure, CO solubility in mixed octene was larger than that of H2. The maximum relative error of the experimental data with the calculation results for H2 and CO were 11. 3% and 6.6% respectively.
