<p>Liquid fuel based on pulverized coal, water and additives, the coal content being at least 55 %. The fuel is suitable for transport in pipelines or direct combustion. A heavily increased dispersion effect as compared with prior art additives is achieved by chemical addition or connection of several aromatic rings to a hydrophilic polymer chain. The polymer chain preferably comprises an anionic or non-ionic graft block copolymerisate. </p> |
