摘要

Abstract

Thisworkwas focused on the measurement of the solubility of hydrogen (H

) in anthraquinoneworking solution at temperatures of 30.0-80.0℃ and pressures of 0.2-3.0 MPa by the method of experimental and COSMO-RS model study. The influence of various factors

i.e.

including pressure

temperature and solvent volume ratio

on H

solubility was investigated. According to the experimental results

solubility in anthraquinone working solution increases with the increase of pressure. At low pressures

the temperature had little effect on H

solubility while under high pressures H

solubility increases with increasing temperature. Henry's constant ln

has a good linear relationship with 1/

(ln

=-1319.1/

+9.91). The effect of volume ratio of trioctyl phosphate to trimethylbenzene on the solubility of hydrogen was studied and the results showed that increasing the amount of trimethylbenzene was conducive to the dissolution of hydrogen. In addition

there is a linear relationshi

p between ln((

)/(

)) and the time

. Gas-liquid mass transfer coefficient was obtained by calculating the slope of the line.
