Problems solved by technology

However, there are still problems of narrow applicable coal types and high cost
[0012] Therefore, for the above-mentioned problems that most additives cannot solve, such as high price, poor adaptability to coal types, low stability, etc., the development of CWS additives with high cost performance and wide adaptability to coal types can promote the development of CWS. Improve the economic efficiency of the enterprise

Abstract

The invention relates to the technical field of additives, and particularly discloses an application of a coal water slurry additive. The application comprises the following steps of manufacturing, liquid preparation and mixing of the coal water slurry additive. The dosage is small, and efficiency is high. The prepared coal water slurry is low in surface viscosity, high in concentration and good in stability. Meanwhile, the coal water slurry additive can be used for coal of different metamorphic grades and is high in applicability.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to the application of an additive for coal water slurry. 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...
