Because the coal tar (high temperature) wash oil from the high temperature coal tar fractionation of various coking plants, because the process is different, the wash oil of coal tar also has differences, its viscosity, color, and specific gravity are all different (Shanxi high temperature There are differences in coal tar wash oil and high temperature coal tar wash oil produced in Chongqing and Jilin's high temperature coal tar wash oil, etc.), so the process reagents in decolorization are also slightly different, but as long as you master the high temperature coal tar The composition, characteristics and regularity, because they are roughly the same, so they are adjusted in the process ingredients and reagents, and the purpose of decolorization is achieved.
