• Influence of Solvent Type on the Behavior of Brown Coal Fractionation Utilizing Solvent Extraction at High Temperature

抄録

We have recently proposed a new coal fractionation method utilizing solvent extraction at lower than 350℃, and have succeeded in separation of bituminous coals into fractions with different molecular weight without decomposition of the coal by the proposed method. For brown coals, not only such separation but also upgrading is essential to recover useful fractions. And it is important to combine upgrading and separation efficiently. In this research the proposed method was applied to a brown coal using either tetralin or 1-methylnaphthalene as an extraction solvent, and the effect of solvent type on properties of the product was examined. Mild hydrogenation as a means of upgrading brown coals was expected by using the tetralin. It was found that the fractionation method using tetralin could separate the brown coal into fractions having different elemental compositions and significantly hydrogenate the fractions at the same time. The fraction extracted using tetralin, was more abundant in hydrogen and aliphatics than that using 1-methylnaphthalene.
