Abstract

The invention provides a modified wash oil coal water slurry additive and a preparing method thereof. According to the method, wash oil serves as a starting raw material, and is subjected to a sulfonation reaction with concentrated sulfuric acid, and then subjected to concentration polymerization with glucose allyl amide and formaldehyde under a certain technology condition, after the reaction is finished, under existence of an initiator, the product is subjected to a polymerization reaction with vinyl phosphoric acid, salt of vinyl phosphoric acid and a cross-linking agent, finally an alkaline conditioning agent is added for carrying out neutralization, and the product is cooled and discharged to obtain the modified wash oil coal water slurry additive. The coal water slurry additive product contains multiple functional groups such as a glucosyl group, a phosphate group, an amide group and a sulfo group and has the advantages of being small in mixing amount, excellent in dispersity, high in stability and the like.

Description

technical field [0001] The invention belongs to the field of fine chemicals, in particular to a modified oil-washing coal-water slurry additive and a preparation method thereof. Background technique [0002] Energy has always been the basis for the progress and development of human society. According to the latest prediction results of the U.S. Energy Information Administration, with the development of the world economy and society, the world's energy demand will continue to increase in the future. China is a big country in energy production and consumption, and energy plays an absolutely important role in the development of the national economy. From the analysis of my country's energy structure, my country is a country rich in coal, poor in oil and little in gas. my country's coal reserves account for about 90% of the total petrochemical energy reserves, while oil and natural gas reserves account for about 10%, and coal consumption accounts for about 72%. . Therefore, fo...
