The solubility equilibria between No.1 light gas oil and liquid SO_2 as well as the distribution of the sulfurous,nitrogenous,and some unsaturated com- pounds(94% H_2SO_4 soluble)in above two phases at -10°,0° & 20℃ were presented. In comparison with other solvents,liquid SO_2 is an excellent solvent for refining shale oil,as it has better selectivity and higher capacity for extrac- tion of sulfur and nitrogen compounds.It was found that at 0℃,with liquid SO_2/oil ratio 0.65(volume ratio)and two theoretical stages,the refined pro- ducts satisfy the requirements for the kerosene and light diesel oil. A method for the solubility equilibrium prediction and an empirical for- mula for calculation of the refined product yield were also given.
