OSTI ID:6559159
Solvent pretreating of coal fines prior to briquetting results in coal briquettes which have no added binder and which will withstand weathering conditions better than binder containing briquettes. The solvents are generally described as organic Lewis base solvents which are capable of electron donor action, and include among others, acetone, methyl ethyl ketone, and ethylene diamine.
