Abstract

The invention relates to the technical field of additives, and particularly discloses a multi-component water-coal-slurry additive. The additive comprises the following components in percentage by weight: 30 to 50 percent of an aliphatic dispersant, 10 to 30 percent of a lignin-based dispersant, 10 to 20 percent of a melamine dispersant, 2 to 5 percent of a grinding aid, 10 to 20 percent of a stabilizing agent, and 5 to 10 percent of an auxiliary agent. The additive is low in dosage and high in efficiency, and the prepared water coal slurry is low in surface viscosity, high in concentration and good in stability; as the additive can be applied to coals with different metamorphic grades, the additive has wide applicability.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to a coal water slurry additive. Background technique [0002] As one of the clean coal technologies, coal-water slurry gasification has been widely used in China after years of continuous scientific and technological research and production practice since its research and development in the early 1980s, and its production and application scale rank first in the world. High-concentration coal-water slurry not only maintains the original physical and chemical properties of coal, but also has good fluidity and stability like petroleum, and its safety is better than petroleum. Coal-water slurry, as an ideal fuel-saving fuel substitute, has received widespread attention from all over the world as soon as it appeared. With the rapid expansion of the coal chemical industry led by coal-water slurry gasification, the application scale of gasified coal-water slurry will maintain a strong ...
