Miroshnichenko D. Optimization of reactiivity as an integral index of coke quality

An object in the dissertation work is the process of formation process under the action of raw materials and process factors of mechanical, physical- chemical, thermochemical properties of coke at the level of its molecular, grain and lump structures. The subject of research is reaction capacity as an integral characteristic of quality of coke. The purpose of the work was basic principles of formation of reaction capacity and thermomechanical strength of coke as a product of thermomechanical conversion of initial coal of different organic and mineral composition and development of the scientifically grounded techniques of regulating the reaction capacity and t thermomechanical strength of coke. Standard methods of studying of process properties of coal and different properties of coke are used in work. Scientific novelty of the results - kinetics of gasification and the mechanism of destruction during thermomechanical tests of coke was studied for the first time. A method was developed on the prognosis of reaction capacity (CRI) and strength of coke after reaction (CSR) of coke on the basis of proximate analysis of the raw material base of coking or chemical composition of its ash. The practical value - technological receptions which are instrumental in adjusting of reactionary ability of blast-furnace coke are developed; the method of method of complex estimation of quality of coke is improved on the indexes of reactionary ability and thermomechanical durability.. The area of application of the results of the work is coke making.
