Low-rank coal to water-coal slurry
Thread Content
Regarding the production of water-coal slurry from low-rank coal, especially slurry for use as a raw material in the chemical industry, are there any good technologies available at present? I would appreciate your guidance. The main methods for concentrating coal slurry include the use of additives, grading, and coal blending. However, low-rank coals have high internal moisture and ash content, resulting in an unsatisfactory slurry concentration; a large amount of chemicals is required, which increases costs, yet the slurry-forming properties remain poor. Are there any good methods to improve the slurry-forming properties of low-rank coals such as lignite? Where can such technologies be found? Where are the demonstration projects? Hope everyone can offer some guidance?

Super fine grinding can be used to increase the concentration of water-coal slurry; coal upgrading can also be employed, with semi-coke being used to raise the concentration of water-coal slurry. . . . . . . . . . . . . . . .
