Abstract
A pumpable aqueous suspension of slag, fly-ash, char, and mixtures thereof which contains a surfactant and has a reduced viscosity and increased resistance to sedimentation. The aqueous suspension is produced by quench cooling and/or scrubbing a raw effluent gas stream from the partial oxidation of solid carbonaceous fuel. It may have a solids content of about 1.0 to 50.0 weight percent. The surfactant comprises an anionic or nonionic adduct of an alkyl phenol and polyoxyethylene or polyoxypropylene. In one embodiment, a solid carbonaceous fuel is wet ground with the aforesaid aqueous suspension and make-up water, if any, to produce a stable aqueous slurry feed to the partial oxidation gas generator.
