Method for preparing shaped coal for coking by adding industrial discarded binding agent
The invention discloses a method for preparing shaped coal for coking by adding an industrial discarded binding agent. The method is used for preparing the shaped coal with low cost. According to the technical scheme, the preparation method comprises the steps of synthesizing a binding agent: mixing phenol residual oil and remnant residual oil, and stirring a mixture so as to form a uniform binding agent for the shaped coal; preparing a shaped coal raw material: adding the binding agent for the shaped coal to coal charges, and stirring at the temperature of 80-150 DEG C; preparing the shaped coal by pressing: feeding the shaped coal raw material into a coal shaping machine, and rolling by using the coal shaping machine so as to obtain the shaped coal for coking. The preparation method has the advantages that the preparation cost of the shaped coal can be effectively reduced by using discarded residual oil materials of coking plants and petrochemical plants as the binding agent for the shaped coal, the environmental pollution caused by waste discharging is avoided, and the circular economy is realized. 1. A kind of interpolation for coking industry to discard the binder forming coal preparation method, is characterized in that the method comprises the following steps: A. Synthetic binder, according to the residual oil and residual phenol residual oil 1:8-15 the mixing ratio of, the mixture at 80-150 the stirring [...] , forming a uniform adhesive for coal; B. Preparation forming coal raw materials, the binder for forming the coal into the coal material, the adding amount of the binder for forming the coal of the of the total weight of the coal raw materials 2%-10%, and the the 80-150 [...] temperature under stirring; C. Press forming coal, the coal sees somebody off in forming coal raw materials, the type of rolling can be formed for coking coal, coal-forming pressure is 10t-20t.
