One of the most essential characteristics of biochar (charcoal) is its higher heating value. The higher heating value for the dry ashless state of 35 samples of raw vegetable materials and charcoal was determined to establish the dependencies between the quality of the raw material and the produced biochar samples. Biochar production was carried out using modernized equipment under the patented technology. Mathematical and graphical dependencies of the experimental and calculated higher heating values for the vegetable raw materials to produce pyrolysis gas and charcoal were established.

This article discusses the production of high-performance fertilizers with promising modifiers. A study of various types of sorbents has shown that the nanoporous structure allows controlling their dissolution in the soil and reducing nutrient losses and greenhouse gas emissions into the environment. Experiments were conducted to produce biochar from various organic raw materials by pyrolysis. The microporous structure of the obtained biofuel samples was studied by scanning microscopy with elemental microanalysis.

The article analyzes the use of biochar in various industries and the national economy (as a sorbent, fuel, reducing agent in the metallurgical industry, a component of coal coke blends, biocomposites, modification of explosives, fertilizers, etc.) It is noted that the direction of use depends on the quality and characteristics of biochar (size, physical properties, chemical composition), which are determined by the nature of the raw material, its chemical composition and carbonization temperature.

The use of charcoal (CC) for various industries was analysed; the modern ideas about the factors influencing the process of obtaining CC were considered. The effect of raw materials nature (wood or agricultural wastes) and their characteristics (size, physical properties, chemical composition), as well as carbonization temperature, heating rate, oxygen level and pressure on the yield and quality of CC was described.

The structure and principle of work of the developed machine for packing wood charcoal is considered. Design features, control system and advantages of the developed automaton are specified.
