在煤液化制得重油中有大量含硫、氮、氧化合物,在直接使用或进一步加工前须先行脱除,高压加氢是一个有效的过程。酚性氧是煤源油品的主要杂环化合物,因而在加氢过程中,它消耗了大部分的氢,文献中对脱硫、脱氮有较多的论述,但对重油的含氧化合物却只有个别的介绍,对这类油品的含硫、含氧化合物的加氢相对反应性更未见报道。制备色谱分离技术,可以将煤液化重油按化学性质的不同,分成9个馏分,如表1所示,这里可以看出:中性油馏分约占73%,它集中了大部分含硫化合物,而含氮化合物却很少;在酸性油馏分中,则主要是含氧 There are a lot of sulfur, nitrogen and oxygen compounds in heavy oil produced by coal liquefaction, which must be removed before use or further processing. High pressure hydrogenation is an effective process. Phenolic oxygen is the main heterocyclic compound of coal source oil, so it consumes most of the hydrogen in the hydrogenation process, the literature on desulfurization, denitrification are more discussed, but the heavy oil oxygenates Only a few individual introductions have made no reports on the relative reactivity of the sulfur-containing and oxygen-containing compounds in such oils. Preparation of chromatographic separation technology, coal liquefaction of heavy oil can be divided into nine different chemical properties, as shown in Table 1, it can be seen here: about 73% neutral oil distillate, which focuses most of the sulfur compounds, While nitrogen-containing compounds are few; in the acidic oil fraction, it is mainly oxygen
