Organically bound metals in a solvent-refined coal: metallograms for a wyoming subbituminous coal.
Fractions of a solvent-refined coal that contain organically bound species of magnesium, calcium, titanium, iron, copper, or zinc have been isolated. The fractions represent a wide range of chemical types and molecular size. Their isolation is a step toward speciation.
