Abstract
Rapid precipitation of the particulate solids e.g. ash, slag, char and mixtures thereof in dilute dispersions of quench cooling and/or scrubbing water as produced in the partial oxidation process for ash-containing solid carbonaceous fuels is effected by mixing with said dispersion an anionic sulfonate surfactant and a water soluble divalent metal salt.
