Hydrocarbon type distribution of the narrow cuts of acid-treated gas oil fraction (166~350℃) from Fushun shale oil crude is studied by use of distillation, adsorption and urea extractive crystallization techniques. 89—90% by weight of hydrocarbons and 10—11% by weight of non-hydrocarbons are found in each narrow cut.

Hydrocarbon type distribution of the narrow cuts of acid-treated gas oil fraction (166~350℃) from Fushun shale oil crude is studied by use of distillation, adsorption and urea extractive crystallization techniques. 89—90% by weight of hydrocarbons and 10—11% by weight of non-hydrocarbons are found in each narrow cut. The content of paraffinic and cycloparaffinic hydrocarbons increases from 31.3% to 41.0% as the boiling point of the fractions is raised, and in which two-third of the saturates are composed of paraffins with straight chain structure. The amount of unsaturates is about one-third of each fraction and about half of the unsaturates are olefins of normal structure. The content of aromatics differs slightly in different cuts. In analogous manner, hydrocarbon type composition of wide cut of gas oil (166~350℃) from Fushun shale oil crude is studied, except that the separation of hydrocarbons and non-hydrocarbons is effected by elution chromatography instead of acid treatment. The hydrocarbons thus obtained amount to 73.5%, whereas non-hydrocarbons are 26.5% (with nitrogenous compounds predominating). In the hydrocarbon portion, normal paraffinic, cycloparaffinic and branched paraffinic, normal olefinic, isoolefinic and cycloolefinic, monocyclic aromatic and polycyclic aromatic hydrocarbons amounts to 20.4, 7.4, 13.9, 12.1, 8.5 and 9.6% respectively. Apart from that, about 1.6% dark colored tarry matter is separated from the hydrocarbon portion. A simplified procedure for the hydrocarbon type analysis of gas oil fraction from shale oil crude by adsorption chromatography is also recommended.

本文首先介紹了撫順頁岩油酸洗油166~350°各窄餾分的化學組成。所應用的研究方法為蒸餾、吸附及尿素結晶抽提等,其中以吸附分離為主.試驗結果說明各餾分含有89~90%(重量)的烴及10~11%的非烴,烷-環烷的含量隨着餾分沸點的昇高而增大,由31.3%增至41.0%,其中正構烷約佔三分二。不飽和烴約佔各餾分的三分之一,其中直鏈烯約佔一半。各餾分中芳煙的含量大致都很接近。又應用類似的方法對撫順頁岩油柴油寬餾分(166~350°)進行了詳細烴族組成研究。不同之處就是應用了粗孔硅膠作為吸附劑的冲洗色譜法代替酸洗祛分離煙與非烴。所得結果烴部分為73.5%,非烴部分為26.5%(以氮化合物為主)。烴部分中有正構烷20.4%,異構烷-環烷7.4%,直鏈烯13.9%,異構烯-環烯12.1%,單環芳烴8.5%及多環芳烴9.6%。烴部分中還分出了1.6%黑色粘稠的非烴物質。還建立了一個測定頁岩油柴油餾分烴族組成的簡易色譜方法。本法用活性細孔硅膠作為吸附劑,分離是以冲洗色譜法為基礎的。

Investigations of hydrogenation of No. 1 light gas oil and absorbed oil from Fushun oil shale at 70 and 200 atm. with catalyst MoS_2-active carbon were made. The hydrogenate above 220℃ from hydrogenation of No. 1 light gas oil at 70 atm. can be used as No. 10 diesel oil, and the fraction below 220℃, if mixed with the absorbed oil and hydrogenated at 70 atm. once more, can produce jet fuel T-2. It was found that the 50% boiling point range 150—182℃ of the hydrogenate may be considered as the main constituent of jet fuel. In one stage hydrogenation of No. 1 light gas oil at 200 atm. with MoS_2 catalyst, the yield of jet fuel T-2 is 24.7%. If submitted the diesel oil fraction to further destructive hydrogenation, 12.9% jet fuel and 22.9% base oil of aviation gasoline were obtained.

中国某些产地的原油具有低硫、高石蜡烃和低芳烃含量的特性。用这类原油炼制所得的减压柴油馏分具有同样特征,因而预测将有良好的裂解性能。为此进行了工艺研究。 在处理量约为2公斤/时,温度和压力分布可以模拟的裂解装置中,进行了中国减压柴油动力学研究和裂解产品分布规律试验。根据模试结果;综合中试和部分工业数据,提出了减压柴油裂解反应速度常数方程的有关参数值,以及原料特性和工艺参数对裂解产品收率关联图及数学关联式。 在处理量为100公斤/时的中试裂解装置中进行产品分布试验和工艺过程有关技术研究,着重考察了炉管对流段、辐射段的运转情况、高压急冷锅炉的操作特性。 研究结果表明,在760℃中等裂解深度时,汽油比为0.75—1,停留时间0.4—0.5秒,烃分压0.8公斤/厘米~2,主要产品收率为:乙烯22.5—23%,丙烯16—17.5%,丁二烯4.7—5.2%,重质燃料油10—12%。该油品与国外中东轻柴油裂解所得产物收率相仿,是工业管式炉的一种好原料。
