Coal-oil slurries containing a surfactant
Patent
·
OSTI ID:5903920
Unwanted settling in a composition comprising a suspension of fine particles of coal in fuel oil is eliminated or substantially reduced by adding an effective amount of a polyoxypropylenepolyoxyethylene copolymer which corresponds to the formula: y((C2h4o)m(C3h6o)nh)x wherein Y is the residue of an organic compound having from about 1 to 6 carbon atoms and containing X reactive hydrogen atoms in which X has a value of at least one, M has a value such that the oxyethylene content of the molecule is from about 10 to 40 weight percent and N has a value such that the total molecul weight of the polyoxyalkylene groups is from about 2000 to 6000.
