Abstract

PURPOSE: To effect efficient wet granulation of a coal powder in a short time, by adding a binder oil emulsion prepared in the presence of a specified nonionic surfactant to an aq. slurry of the coal powder followed by agitation.
CONSTITUTION: A nonionic surfactant of formulaIor II (wherein R1 is 8W12C alkyl or alkenyl; R2 is 8W18C alkyl or alkenyl; n1 is 4W12; n2 is 9W13) with relatively low emulsification ability such as a polyoxyethylene (4 molar) octylphenyl ether or polyoxyethylene (9 molar) lauryl ether is used. An oil component such as fuel oil, a raw material and about 0.01W20wt%, based on said oil component, said surfactant are charged into water and emulsified by mixing at a rate of revolution of a stirring blade tip ≥5m/sec by the use of a line mixer, colloid mill, etc. Then the obtd, emulsion is added as a binder oil to an aq. slurry of a coal powder to granulate the coal powder.
