Coal liquor clarification with water-soluble, high molecular weight polymers having low concentration of cationic moieties |
摘要 |
Coal liquors are clarified by contacting them with high molecular weight copolymers of from about 70 to about 99 mole percent of a nonionic water-soluble monomer such as acrylamide and from 1 to 30 mole percent of a cationic monomer such as methacryloylethyl trimethyl ammonium chloride or methacrylamidopropyl trimethyl ammonium chloride.
