Preparation of Anthracite-based Briquettes Using Coal Liquefaction Residue as Binder

Briquettes for the pressurized gasification were prepared using typical high ash content anthracite as the raw material and the coal liquefaction residue( CLR) as the primary binder. Results demonstrated that the compressive strength of as-prepared briquettes gradually increased with the increasing of molding pressure; nevertheless,the compressive strength decreased after the pressure over the critical point,due mainly to the collapse of coal...
