WhatsApp: +86 18838072829Coal oil is made by heating cannel coal with a controlled amount of oxygen, a process called pyrolysis. Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes.

WhatsApp: +86 18838072829Coal sludge, also known as slurry, is the liquid coal waste produced by mining activities. After mining, coal is crushed and washed to remove the surrounding soil and rock. The washing process generates huge amounts of liquid waste, and the mining process itself produces millions of tons of solid waste. Coal companies usually dispose of this ...
