Original Abstract
Concentrated water-based lignite suspensions (pastes) posses unpleasant flow behaviour. Under extrusion-like conditions suspension is rapidly compacted, viscosity rises considerably and flow effectively ceases. Using diluted aqueous solution of carboxymethylcellulose sodium salt as a dispersion medium eliminates this adverse phenomenon and keeps liquid-like flowing of suspension. Moreover, effective dilatant suspension behaviour is transformed to pseudoplastic.
