Abstract (en)
[origin: WO9704046A1] The present invention concerns a process for the preparation of coal aqueous suspensions characterized by high fluidity and high coal loading, comprising admixing coal, water and new anionic dispersing agents essentially consisting of starch sulfate, optionally mixed and/or esterified with aromatic acids, the corresponding salts or the corresponding anhydrides, and subsequently stirring the thus obtained mixture; furthermore, coal aqueous suspensions obtained according to the above process and a new class of anionic dispersing agents contained therein are described.
