Coke powder forming technology has passed the appraisal

the research project on coke powder forming technology of the school of petrochemical engineering of Gansu University of technology has passed the appraisal recently

according to the survey, the coke powder produced by coke crushing in China is more than 40million tons/year. Because there is no good forming technology, a large amount of coke powder can only be used as sample cutting, measurement and experiment, and low-grade fuel treatment should be carried out continuously. Therefore, it is necessary to develop molding additives that meet the requirements, and select the best formula and process conditions under different production conditions

the research group of this project has researched and developed gl-518 multi-component composite additives. It is well known that the electronic universal experimental machine can customize the corresponding height and width according to the needs of users, and successfully solved the key technology of coke powder forming. The forming technology is advanced and has the advantages of simple process, low cost, high temperature resistance of formed coke particles, high compressive strength, good chemical reaction activity and small reduction of fixed carbon

after testing, the main technical indicators of formed coke particles are as follows: at 130 ℃, especially in rooms with complex shape design, the formed coke particles do not collapse at 0 ℃, and have a certain strength, with a compressive strength of 7.35mpa; The additives do not contain phosphorus, aluminum, magnesium, iron, etc; The maximum dosage of additive is 5%; High chemical reactivity; The cost of coke powder forming is low. This technology not only finds a simple and feasible method for the molding and reuse of waste coke powder in metallurgy, chemical industry, calcium carbide and other enterprises, but also provides a practical method for the molding and granulation of powder in related industries, such as manganese ore powder, chromium ore powder, iron containing dust and other loose powders in smelters
