Title:
DESULFURIZATION OF LIQUEFIED COAL
Document Type and Number:
Japanese Patent JPS57200489
Kind Code:
A
Abstract:
In a solvent refined coal liquefaction process, more effective desulfurization of the high boiling point components is effected by first stripping the solvent-coal reacted slurry of lower boiling point components, particularly including hydrogen sulfide and low molecular weight sulfur compounds, and then reacting the slurry with a solid sulfur getter material, such as iron. The sulfur getter compound, with reacted sulfur included, is then removed with other solids in the slurry.
