The determination of hydrocarbon types in heavy straight run distillates of petroleum by high ionizing voltage, low resolution mass spectrometry is described. The sample is at first separated into saturate and aromatic fractions by silica gel percolation, and the two fractions are then treated by mass spectrometric analysis separately. The results show that the saturate fraction contains saturated hydrocarbon types, including alkanes(0-ring), single-ring naphthenes and five fused naphthene types with 2-6 rings....

The determination of hydrocarbon types in heavy straight run distillates of petroleum by high ionizing voltage, low resolution mass spectrometry is described. The sample is at first separated into saturate and aromatic fractions by silica gel percolation, and the two fractions are then treated by mass spectrometric analysis separately. The results show that the saturate fraction contains saturated hydrocarbon types, including alkanes(0-ring), single-ring naphthenes and five fused naphthene types with 2-6 rings. A small quantity of mononuclear aromatics is also found in the saturate fraction. Aromatic fraction contains 18 aromatic hydrocarbon types and 3 aromatic thiophenotypes. This method is simple and reliable. The composition data of lubricating oils, catalytic cracking feed stocks, and some paraffin waxes from Daqing, shengli, Renqiu, Dongpu, Changqing and Yangsanmu crude oils are also presented. These data are useful in heavy oil processing studies.

本文介绍了用低分辩、高离子化电压质谱测定石油直馏重馏分油烃类组成的方法。样品首先用硅胶吸附预分离为饱和烃和芳香烃,然后分别进行质谱分析。饱和烃部分含七个类型的饱和烃以及少量单环芳烃。芳香烃部分含十八个类型芳烃及三个芳烃噻吩。本方法简便、可靠。本工作配合重油加工工艺的研究,提供了大庆、任丘、东濮、长庆、胜利及羊三木六种原油中润滑油、催化裂化原料油和几个蜡样的详细组成数据。

The chemical composition of eleven residues, including feedstocks, heavy cycle oils and clarified oils of catalytic cracking, was analyzed by LC, MS, ~1H and ~(13)C NMR, AAS, VPO, elemental analyses, etc.,Based on these analyses the change of chomical composition of residues during catalytic cracking was observed, showing that most atmospheric residues of Chinese crude oils have good crackability and can be directly used as feedstocks for resid cat-cracking, and most vacuum residues can be blended in part with...

The chemical composition of eleven residues, including feedstocks, heavy cycle oils and clarified oils of catalytic cracking, was analyzed by LC, MS, ~1H and ~(13)C NMR, AAS, VPO, elemental analyses, etc.,Based on these analyses the change of chomical composition of residues during catalytic cracking was observed, showing that most atmospheric residues of Chinese crude oils have good crackability and can be directly used as feedstocks for resid cat-cracking, and most vacuum residues can be blended in part with VGO as resid cat-cracking feeds. Aromatics in >359℃ heavy cycle oils and clarified oils are mainly polyaromatics with less and short side chains which are difficult to crack. The coke yield can be reduced by drawing off all or part of them trom the cracking unit. Appreciable amount of the resins in residues can be converted into smaller molecules during resid cat-cracking.

本文应用液体色谱,质谱,~1H和~(13)C核磁共振波谱,原子吸收光谱,元素分析和分子量测定等手段分析了多种催化裂化原料油,循环油和澄清油的化学组成,并在此基础上研究了渣油在催化裂化过程中组成的变化。研究结果表明,我国大多数原油的常压渣油有较好的裂化性能,是良好的催化裂化原料;多数减压渣油可掺入减压蜡油作为催化裂化原料。渣油经裂化后,大于350℃的芳香烃是一些难以裂化的物质,部分或全部除去可以减少焦炭的生成。我国渣油中含量较高的大分子胶质有相当一部分可裂化为小分子烃类和非烃化合物。
