ABSTRACT With the development of oil refining technology, petroleum coke, especially petroleum coke with high sulfur is becoming industrial waste.

随着炼油工业的发展，石油焦，特别是高硫石油焦成为工业废物。

The temperature effect on the oil yield was discussed at first. Then, analytical work was carried out as follows: the ultimate analysis and physi-chemical analysis of the pyrolytic oil comprised a sketch of the fuel properties of the oil; Then, through the distillation analysis of the oil, the fraction composition of the "unrefined"oil was known. After that, a general knowledge of the aromaticity and saturation of the hydrocarbons in the oil was provided by the outcome of the FT-IR functional group analysis. Also, from the analysis, the form of the polar functional groups and their distribution in different fractions of the oil were learned.

文中首先对不同热解温度下热解油产率进行分析讨论，然后，针对热解油品质进行了一系列分析：通过元素组成和理化特性的分析，对热解油作为燃料特性有了一个大致了解；通过实沸点蒸馏分析，得到热解油作为一种未提炼油的馏分分布，并为后续热解油馏分的细入分析提供了前提；通过对热解全油和各窄馏分的FT-IR官能团分析，对热解油的芳香性、不饱和性有了整体的了解，并且清楚了热解油中的极性官能团存在型式及其在热解油不同馏分中的分布。

Objective There exists the occurrence possibility of acute poisoning accident in the oil refining process in the petrochemical company. The quantitative risk analysis was made predictively for the consequence of acute poisoning caused by high toxic substances in order to put forward the countermeasures scientifically on the aspect of emergency rescue and management.

目的 某新建石油化工企业炼油生产工艺过程存在急性中毒事故的可能性，针对高毒物质造成的急性中毒后果进行定量预测分析，以科学地在应急救援及管理方面提出相应的对策。

Sinopec is Asia's biggest refiner, with a smaller presence in oil and natural-gas production.

中石化是亚洲最大的炼油企业，石油和天然气的生产规模则相对较小。

According to the company newsletter, the nation's biggest oil refiner has cut back on supplies to Hunan, Hubei and Guangdong.

根据该公司的公告，这个中国最大的炼油公司已经降低了湖南、湖北与广东的供应量。

But I hope to learn about modern refinery systems, too.

同时也希望能学到现代炼油的方法。

"Why are these people in the refinery?"

"为什么这些人会进入炼油装置去？"

Temperature control of heating furnace outlet is often applied in petroleum refinery and chemical industry.

问题的提出加热炉出口温度控制是炼油、化工生产中经常使用的控制方案。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
