Abstract
PURPOSE: The titled additive capable of stably dispersing powder coal in an alcohol, which comprises a compd. having a SC3H group or OSO3 group.
CONSTITUTION: A compd. having a SO3H group or OSO3 group in the molecule such as an alkylbenzenesulfonic acid or 2-sulfo fatty acid ester, or a metal salt, amine salt, ammonium salt, etc. thereof is used as an additive for a coal/alcohol slurry. About 10W90wt% powder coal of particle size ≤100 mesh, about 5W 85wt% alcohol such as methanol and about 0.05W2wt% said additive are mixed to form a coal/alcohol slurry with prolonged excellent dispersion stability.
