I overcome the problem of producing high-concentration coal water slurry from lignite
Recently, Shaanxi Yulin West Coal Technology Research Center announced that the center's Ren He Feng team used lignite from Hulunbuir City, Inner Mongolia, using self-developed low-rank coal fine dry powder preparation technology to successfully produce coal slurry
with a concentration of 63.
8% and a viscosity of 1200 centiPa on an industrial pilot production line.
This result reaches and exceeds the concentration of coal water slurry produced from Shenmu's high-quality chemical coal, which marks that China has successfully overcome the worldwide problem of preparing high concentration coal slurry from lignite, and made the efficient and clean utilization of lignite a reality
.
Industry experts said that if the technology is promoted and applied in the field of coal chemical industry, it will bring at least 20 billion yuan in revenue
every year.
