emulsification stabilizer of coal water slurry

Lignosulfonate is a product obtained after sulfonation of lignin. Lignosulfonate can be directly extracted from the waste liquor of sulfite pulping, or it can be obtained by sulfonating papermaking black liquor or lignin under certain conditions. Lignosalts have been widely used in metallurgical manufacturing, cement building materials, agricultural soils, livestock feed, road paving, oil exploration and other fields. The emulsification stabilizer of coal water slurry can make the coal ash into a stable coal water slurry and then burn it, which can make full use of heat energy. This is a major advancement in energy technology. How to make a slurry with good stability and low viscosity is the key to the end , And lignosulfonate is a suitable surfactant for this system.
