Abstract: The relevance of the work is determined by the fact that the yield of the main products of coco-chemical production is the most important factor determining the technical and economic indicators of production. Prediction of the yield of coking products from coal raw materials is necessary both for designing of new coke and chemical enterprises, and for evaluation of the operation of existing plants.
This paper presents the results of a study of the relationship between the yield of chemical coking products and the petrographic characteristics of coal.
Nine samples of coking coals of technological grade Ж (fatty), which were characterized by the data of technical, elemental, and petrographic analyses, were used as objects of the study. It was established that among the samples of the same brand, differences were observed in the carbon content, hydrogen, and yield of volatile substances and in the values ​​of vitrinite reflection indices.
The analysis of the applicability of empirical formulas for calculating the yield of chemical products of coal coking by their classification parameters (yield of volatiles, thickness of the plastic layer) and petrographic indicators (reflection coefficient of vitrinite, the sum of thinning components) was carried out. A correlation relationship was found between the yield values ​​of the main chemical products of coking calculated according to the model based on the results of petrographic analysis and the index of chemical potential.

Key words: coal volatiles yield elemental and petrographic analyses chemical coking products yield
