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.

测定了液体二氧化硫和抚顺页岩1号粗轻油在-10°、0°和20°时的液-液平衡溶解度,以及硫、氮和不饱和分在上述两相中的分布情况.试验证明,液体二氧化硫是一种精制页岩油的优良溶剂.与其他溶剂精制法比较,其选择性、脱硫和脱氮效率均较高;在得到相同氮含量和硫含量的产品时,所需的溶剂量及处理段数均最少.确定用二氧化硫精制的适宜条件为:温度0°,溶剂用量比为0.65(体积),处理段数为两段.在上述条件下经过处理后,所得精制油基本上可以合乎煤油和高速柴油的规格.根据实验结果提出了平衡数据的推算方法,并求得计算在不同条件下精制油收率的经验公式.

The liquid-liquid equilibrium data for ternary systems: propionic acid-ethyl aceta te-water at 15℃, butyric acid-ethyl acetate-water at 15° and 30℃, and mixed acids (acetic, propionic, butyric acid)-ethyl acetate-water at 15℃ were determined. Thevapor-liquid-equilibrium data for binary systems of acetic-propionic acid, propionicbutyric acid, and acetic-butyric acid under normal pressure were also given. The authors regarded that the non-ideal behavior of vapor-liquid equilibrium is mainly attributed to the vapor phase association between molecules, and they derived a correlative equation for calculating the vapor-liquid equilibria in case of molecular association. The vapor-liquid equilibrium data for acetic-butyric acid calculated by the equation derived check with the experimental result.

测定了15℃时丙酸,15℃及30℃时丁酸和15℃时乙、丙、丁混合酸在乙酸乙酯和水中的液-液相平衡数据。也测定了乙酸-丙酸,丙酸-丁酸及乙酸-丁酸三个二元系统在760毫米汞柱压力时的汽-液平衡。我们认为汽-液平衡的非理想主要是由于汽相分子的缔合。于是推导了计算分子缔合时的汽-液平衡关系式,推算的乙酸-丁酸二元系统的汽-液平衡数据和实验结果相符合。
