油馏分 meaning in Chinese
oil fraction
Examples
- Experimental research on synthesis of dispersing agent for coal water slurry with fraction of naphthalene oil
萘油馏分合成水煤浆分散剂的试验研究 - The gasolene , kerosene , and the gas oil fractions are purified to remove unwanted materials , mainly sulphur compounds
汽油，煤油，和气体油馏分被提纯以去除不想要的物质，主要是硫化物。 - Bitumen and bituminous binders - determination of recovered binder and oil distillate from bitumen emulsions by distillation
沥青和硬沥青粘合剂.用蒸馏法从乳化沥青中回收的粘合剂和油馏分的测定 - 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。
