Abstract
PURPOSE: To obtain the titled additive which enhances agglomeration of coal powder in a coal slurry and increases recovery ratio for the coal powder without any complicated procedure by addition to the coal slurry together with an oil, which comprises a nonionic surfactant prepd. by the addition of ethylene oxide to an aliph. alcohol.
CONSTITUTION: An additive for the agglomeration of coal powder comprising as an essential component a nonionic surfactant of HLB 7W11, prepd. by the addition of ethylene oxide to a 12C or higher aliph. alcohol, pref. a 15C or higher aliph. alcohol, more pref. a 15C or higher aliph. alchol contg. at least one unsaturated bond, for recovering coal powder from a coal-water slurry contg. 1W65% coal by use of an oil. It is possible for the additive to remarkably enhance agglomeration of the coal and to exceedingly increase recovery ratio for the coal powder by mixing with a coal slurry together with an oil such as crude oil, heavy or kerosene.
