摘要

Abstract

In this work

the solubility data and liquid-phase mass transfer coefficients of hydrogen (H

)

methane (CH

) and their mixtures in vacuum gas oil (VGO) at temperatures (353.15-453.15 K) and pressures (1-7 MPa) were measured

which are necessary for catalytic cracking process simulation and design. The solubility of H

and CH

in VGO increases with the increase of pressure

but decreases with the increase of temperature. Henry's constants of H

and CH

follow the relation of ln

=-413.05/

+ 5.27 and ln

=-990.67/

+ 5.87

respectively. The molar fractions of H

and system pressures at different equilibrium time were measured to estimate the liquid-phase mass transfer coefficients. The results showed that with the increase of pressure

the liquid-phase mass transfer coefficients increase. Furthermore

the solubility of H

and CH

in VGO was predicted by the predictive COSMO-RS model

and the predicted values agree well with experimental data. In addition

the gas-liquid equilibrium (GLE) for H

+ CH

+ VGO

system at different feeding gas ratios in volume fraction (

i.e

85% + CH

15% and H

90% + CH

10%) was measured. The selectivity of H

to CH

predicted by the COSMO-RS model agrees well with experimental data. This work provides the basic thermodynamic and dynamic data for fuel oil catalytic cracking processes.
