氢气在烃类混合溶剂中高压溶解度的测定
DETERMINATION ON THE SOLUBILITY OF HYDROGEN IN HYDROCARBON MIXTURES AT HIGH PRESSURES
摘要
Abstract
In order to research the regular pattern of hydrogen dissolved in coal liquefied oil and hydrogen consumption in the coal direct liquification process, data on the high-pressure solubility of hydrogen in hexadecane-1,2,3,4-tetrahydronaphthalene, 1,2,3,4-tetrahydronaphthalene-quinoline, hexadecane-quinoline at temperatures from 453.15 K to 623. 15 K and pres sures from 1 MPa to 10 MPa were determined with an experiment-established apparatus that measured the solubility in vapor-liquid phase equilibrium sampling way. Meanwhile, the regular pattern of hydrogen dissolved was revealed in these mixed solvent system. A mathematical model based on Pierotti method and Henry law is proposed. Calculation of solubility of hydrogen in these mixed solvent system with the mathematical model that the expression of model is lnrH2= -a/T + bT+ clnT+dlnpH2 +e, in which related parameters in model is obtained by regression of known solubility data for different solvents showed that the average absolute deviation(r)between regression values and experimental results is around 5.52％, while the average absolute deviation between calculation of solubility of hydrogen in these mixed solvent system with P/N/A model and experimental results is larger. The study indicated that the mathematical model has best application value in counting solubility of hydrogen in organic solvent mixtures.关键词
