ABSTRACT:
Imidazoline quaternary salts are added to oil slurries of solid particulate carbonaceous material such as a coal oil mixture (COM) or a coke oil mixture to stabilize the slurry during storage and dispensing at various temperatures. The imidazoline quaternary salts are added to either the oil or slurry (or during the grinding of the carbonaceous material) and are effective with or without the addition of water. Coal/coke oil slurries may contain from about 40 to about 90 parts by weight of oil, about 10 to about 60 parts by weight of powdered coal or coke, about 0.01 to about 6.0 parts by weight of imidazoline quaternary salt and about 0 to about 10 parts by weight of water.
