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.

In this paper, the random copolymers of polyaryl ether ketone ketone and polyaryl ether ether ketone ketone sulfone were synthesized from terephthaloyl chloride, isophthaloyl chloride, diphenyl ether and 4, 4'-diphenoxyldiphenyl sulfone by low-temperature solution polycohdensation in the presenee of Nmethylpyrrolidone with AlCl_3 as catalyst and 1, 2-dichloroethane as solvent. The copolymers were characterized by IR, DSC, TG, X-ray and solubility test in common solvents. The research shows that melting temperatures and crystallinities of the copolymers decrease with increasing sulfone groups content in maromolecular chains, but they still exhibit excellent solvent resistance and thermostability properties.

In this paper, the process for preparing petroleum resins from the C_9 fractions from light oil pyrolysis was studied in detail. The total yield of resins made by the two-step method of radical and cationic polymerization is higher than 60%. The polymerization catalysts were removed by terminating agent and filtration instead of the conventional water washing method to avoid pollution of the environment caused by waste water containing fluorine. Laboratory and pilot plant results indicated that the dark colored resins had excellent solvent compatibility, and the Gardner color of light colored resins was below 8 with a softening point of higher than 120℃.
