Method for hydrogenating a solvent-refined coal

A method for hydrogenating a solvent-refined coal, comprising: (a) hydrogenating coal in the presence of a hydrocarbon solvent and an iron catalyst; (b) obtaining a solvent-refined coal material therefrom, which has a boiling point of at least 400 DEG under atmospheric pressure conditions; (c) remov...

Beschreibung
Zusammenfassung:	A method for hydrogenating a solvent-refined coal, comprising: (a) hydrogenating coal in the presence of a hydrocarbon solvent and an iron catalyst; (b) obtaining a solvent-refined coal material therefrom, which has a boiling point of at least 400 DEG under atmospheric pressure conditions; (c) removing preasphaltenes from said solvent-refined coal material to obtain a substantially preasphaltene free solvent-refined coal; and (d) hydrogenating the solvent-refined coal in a fixed bed under hydrogen pressure.
