The target of investigation - to study regularities of gaseous products formation during thermolysis of BC-CCW mixtures modified by inorganic alkalies or acids, liquid CCW; and to determine ways of conversion products usage.The methods of investigation: modification of BC and BC-CCW mixtures by chemicals; thermoconversion (pyrolysis) of modified samples and their mixtures with liquid wastes; study of thermolysis gaseous products content by gas chromatography, of solid products - by X-Ray and IR-spectroscopy.Products of thermolysis and activation of brown coal-liquid wastes mixtures modified by acid, КОН, FeCl3, NH4NO3 have been studied. The data about reactions and processes that take place during modification and thermolysis of coal, liquid wastes and their mixtures have been generalized. The dependences of gas content on thermolysis conditions, modifier and wastes nature have been revealed. The joint of coal modification and petroleum waste involving enriches thermolysis gaseous products with combustible components (Н2,СО, alkalnes), that allows to obtain gas with calorific value up to 42 МJ/m . It has been developed the way to improving metallurgical coke quality which implies coke treatment by water solution of sodium tetraborate and cetylthreemetylammoniun bromide at 20 - 50оС, that is essentially decreases its reactivity (CRI index) and increases hot strengths (CSR index). Results of work are focused on creation of technology of simultaneous thermochemical conversion of brown coal and industrial wastes into different products including highly combustible gaseous products as natural gas substitutes and raw material for FT-synthesis.
