A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700° F. and typical pressures between 200 and 3,000 psi, according to known liquefaction processes.

 · variations in ash content. In addition fine coal is sometimes placed together with other materials and this also affects the scope for utilisation. Historically, blending, briquetting and drying have been adopted to facilitate use of fine coal. This report considers the scale of the resource that these residues represent at global and national ...
