Solvent extraction of nitrogen compounds from coal liquids

Solvent extraction of nitrogen compounds from coal liquids

Nitrogen compounds were separated efficiently from coal liquids by solvent extraction with methanol and water. Middle distillates of Wandoan and Battle River coal liquid and a mixture of model compounds were employed as feed oils. This paper reports the experimental conditions for the effective sepa...

Zusammenfassung:Nitrogen compounds were separated efficiently from coal liquids by solvent extraction with methanol and water. Middle distillates of Wandoan and Battle River coal liquid and a mixture of model compounds were employed as feed oils. This paper reports the experimental conditions for the effective separation of nitrogen compounds, such as quinoline and indole. In particular, the effects of extraction solvents on extraction yield and selectivities of nitrogen compounds were investigated.
