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。

考察了硝基甲烷对撫順頁岩油各餾分的萃取选择性。測定了其与撫顺2号粗輕油在20°和40°时的液-液平衡溶解度,以及氮、主烴和非烴等在平衡相中的分布。并进行了以硝基甲烷为溶液的三段逆迴間断式与小型連續逆流式的撫順2号粗輕油溶剂精制。根据試驗結果与相图計算,提出了較适宜的工业抽提操作条件:溫度为20°,溶剂比为2(重量),抽提塔的理論塔段数为5;并証明硝基甲烷为精制頁岩油各餾分的优良选择性溶剂,其对頁岩油中氮化合物的萃取选择性較之液体二氧化硫与80%酒精均高。硝基甲烷溶剂精制油經少量稀硫酸輔助洗滌后,所得到的輕柴油品貭优良,安定性极高。
