Coal-water dispersion |
摘要 |
A storage stable aqueous pulverized-coal dispersion can be pumped and can be burned by conventional techniques. The dispersion comprises stabilizing additives and a coal content which ranges from 60 to 80% by weight. The additives include a combination of (a) sufficient lecithin adsorbed on surfaces of coal particles to provide repulsion between the coal particles by hydration forces and (b) polymer cooperating with the lecithin and comprising at least one polymer having segments of hydrophobic as well as segments of hydrophilic character.
