Problems solved by technology

In recent years, China University of Mining and Technology, Anhui University of Science and Technology and Shanxi University of Science and Technology have done some research on this subject. The proposed emulsified diesel collectors and their preparation methods are different. The biggest problems are poor stability, poor selectivity, The yield is low, it cannot be applied industrially, and it can only stay in the experimental stage. Therefore, it is particularly important to develop an emulsified diesel collector with high stability, good selectivity, and high yield

Abstract

The invention provides an industrial coal slime emulsified diesel oil collector and a preparation method thereof. The collector comprises LAE9, sodium petroleum sulfonate, 8-DEG C oleic acid, sesame oil sodium soap, dodecylbenzenesulfonic acid, diesel oil and water. The diesel emulsion prepared by the method has high stability, selectivity and yield, solves the problem of low emulsion stability caused by the water hardness, can be industrially applied and has the characteristic of saving diesel oil resources; and moreover, the invention can improve the flotation selectivity and yield of the coal slime, has low cost and high efficiency and meets the requirements of energy conservation and environmental protection.

Description

Technical field: [0001] The invention relates to an emulsified diesel oil collector and a preparation method thereof, which are suitable for coal slime flotation in a coal preparation process. Background technique: [0002] Coal preparation is the most basic, economical, applicable and practical way to remove or reduce impurities such as ash, gangue and sulfur contained in raw coal, improve coal quality and reduce pollution. If the current 61.5 billion tons of raw coal consumed by power plants and industrial boilers in the country is changed to washed coal, 65 million tons of coal can be saved each year, and CO2 emissions can be reduced by 3 million tons. Therefore, it is of great significance to give priority to the development of coal preparation. Flotation is one of many coal preparation methods. It uses the difference in wettability of the surface of coal and gangue to separate coal from impurities. It is especially suitable for washing coal slime with small particle si...
