Abstract

The invention belongs to the field of fine chemical engineering and provides a modified aliphatic CWS (coal-water-slurry) additive and a preparation method thereof. The preparation method comprises steps as follows: (1) acetone, a sulfonating agent and water are added to a reaction kettle, heated to the temperature of 30-60 DEG C and stirred for a sulfonating reaction for 1-3 h; (2) cardanol sodium sulfonate and cardanol phosphate are added after the sulfonating reaction ends, evenly stirred and continuously heated to the temperature of 80-100 DEG C, and formaldehyde is dropwise added for 0.5-4 h; (3) unsaturated carboxylic acid, a salt of the unsaturated carboxylic acid and unsaturated aliphatic amine are added to the reaction kettle and evenly stirred, then an initiator solution with the mass concentration of 1%-10% is dropwise added, and the initiator solution is prepared from an initiator and water in parts by weight; the addition time is controlled to be 0.5-4 h, and the temperature is controlled to be 90-120 DEG C during addition; (4) the temperature is kept for a continuous reaction for 1-4 h after addition, and the temperature is reduced for discharge.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a modified aliphatic coal-water slurry additive and a preparation method thereof. Background technique [0002] Energy is an important basic resource for the development of human society. Coal, oil and natural gas are a few conventional forms of energy. Among them, coal is the conventional energy with the largest reserves and the widest distribution in the world. my country is one of the few countries in the world whose energy is dominated by coal, and it is also the largest coal consumer in the world. 84% of China's coal is used for combustion. In the next few decades, coal will continue to play the role of the main energy source in China. However, the direct combustion of coal will produce a large amount of CO 2 , SO 2 , NOx and dust particles and other environmental pollutants will inevitably lead to further deterioration of the global climate and continuous poll...
