Abstract

The invention provides a coal water slurry additive and a preparation method thereof. The method comprises the following steps: (1) adding glucose allyl amide, an alkaline regulator and water into a reaction kettle, starting stirring, and starting heating; (2) after the temperature rises to 55-70 DEG C, adding formaldehyde, continuing reacting for 0.1-1 hour, adding a sulfonating agent, and keeping the temperature for 0.1-1 hour; (3) continuing heating to 70-90 DEG C, adding methyl allyl polyethenoxy ether, unsaturated fatty acid, vinyl phosphoric acid and salt thereof, stirring uniformly, and dropwisely adding a 1-10 wt% initiator solution, wherein the initiator solution is prepared from the initiator and water, the dropwise addition time is controlled at 0.5-4 hours, and the dropwise addition temperature is controlled at 90-100 DEG C; and (4) after the dropwise addition, keeping the temperature to continue reaction for 1-4 hours, cooling and discharging to obtain the coal water slurry additive.

Description

technical field [0001] The invention belongs to the field of fine chemicals, in particular to a coal-water slurry additive and a preparation method thereof. Background technique [0002] Coal accounts for about 72% of my country's total energy consumption as primary energy consumption. For a long time, my country's energy consumption structure will still be dominated by coal. Due to the problems of large environmental pollution and low fuel utilization rate in the traditional coal burning method, with the goal of building a resource-saving and environment-friendly society, there is an urgent need for a clean coal utilization method. [0003] Coal-water slurry is a high-concentration coal-water mixture. As a coal-based oil-replacing clean fuel, it has the characteristics of low pollution, easy pumping, atomization and combustion, and is an important part of clean coal technology. Coal water slurry is a solid-liquid dispersion system composed of 60% to 70% coal, 30% water and...
