Effective solvent extraction of coal and subsequent separation processes

Effective solvent extraction of coal and subsequent separation processes

The Refcoal process is being developed to produce graphite from coal. Coal is dissolved in dimethylformamide (DMF) and sodium hydroxide (NaOH) is used as additive. After separation, the extracted coal (Refcoal) is precipitated with water and dried. The extraction process and subsequent solid-liquid...
