Abstract

The invention provides a coal water slurry dispersant synthesized from petroleum waste phenol residues and a synthesis method of the coal water slurry dispersant. The invention relates to the technical field of coal water slurry dispersants. The raw materials comprise the following components in parts by weight: 10-60 parts of waste phenol residues, 20-100 parts of sodium p-styrenesulfonate, 5-20parts of 32% liquid sodium hydroxide, 0.7-2 parts of ammonium persulfate, 1-3 parts of 27% hydrogen peroxide, 300-600 parts of deionized water, 0.5-1.5 parts of 3M, 200-320 parts of a monomer PEG 200-600, 0.5 to 2 parts of VC, 20 to 40 parts of methacrylic acid, and 2 to 10 parts of hydroxyethyl ester. The waste petroleum phenol residues are used for industrial production, resource waste caused bydirect treatment of the waste petroleum phenol residues is avoided, environmental pollution caused by waste discharge during physical and chemical treatment is avoided, and application of the waste petroleum phenol residues in the new field is achieved.

Description

technical field [0001] The invention relates to the technical field of coal-water slurry dispersants, in particular to a coal-water slurry dispersant synthesized by using petroleum waste phenol residue and a synthesis method thereof. Background technique [0002] Phenolic residues from petrochemical plants have the characteristics of complex composition, high concentration, high toxicity, dark color, and great harm to human body and environment. At present, the more treatment process used is deep oxidation + biochemical, and the deep oxidation process includes iron-carbon internal electrolysis, ozone and other methods. Waste residue treatment is complicated, consumes a lot of energy, and costs a lot. The resulting environmental pollution has not been effectively resolved. The secondary cost of petroleum waste phenol residue is low, and the problem of solving environmental pollution and other problems will definitely play its economic and social benefits in the development ...
