“…Furthermore, sufficient attention has been paid to the development and research of mathematical and simulation models of various pyrolysis plants and their separate components (reactors, circulation systems, heat exchangers, etc.) [25][26][27][28], including the use of fuzzy logic, soft computing and other intelligent techniques [29,30]. Also, currently, a sufficient number of examples of the successful application of intelligent and other advanced algorithms and devices for the implementation of effective control of certain technological variables of waste utilizing complexes have been presented [31,32].…”

control of the pyrolysis process of municipal solid waste (MSW) of variable composition and moisture content. The fuzzy control method is developed and studied that makes it possible to carry out the proper automatic control of the pyrolysis plant with the determination of the optimal ratio of air/MSW for various types of waste and with different moisture content values to ensure high efficiency of the MSW disposal process. The effectiveness study of the proposed fuzzy control method is performed in this paper on a specific example, in particular, when automating the pyrolysis plant for the MSW disposal with the reactor volume of 250 liters. The obtained simulation results confirm the high efficiency of the developed method, as well as the feasibility of its use for designing automatic control systems of various pyrolysis plants that operate under conditions of changes in the composition and moisture content of input waste.

“…The above-described fast pyrolysis kinetic models with the reaction mechanisms and the kinetic data are listed in Table 8. Tuntsev et al (2015) developed a simple mathematical model to simulate the fast pyrolysis of wood waste in a fluidized bed reactor. The model can predict the temperature distribution along the particle radius, the effect of reactor temperature on the kinetics, and the effects of temperature and reactor length on the product yield.…”

Thermochemical processes, which include pyrolysis, torrefaction, gasification, combustion, and hydrothermal conversions, are perceived to be more efficient in converting waste biomass to energy and value-added products than biochemical processes. From the chemical point of view, thermochemical processes are highly complex and sensitive to numerous physicochemical properties, thus making reactor and process modeling more challenging. Nevertheless, the successful commercialization of these processes is contingent upon optimized reactor and process designs, which can be effectively achieved via modeling and simulation. Models of various scales with numerous simplifying assumptions have been developed for specific applications of thermochemical conversion of waste biomass. However, there is a research gap that needs to be explored to elaborate the scale of applicability, limitations, accuracy, validity, and special features of each model. This review study investigates all above mentioned important aspects and features of the existing models for all established industrial thermochemical conversion processes with emphasis on waste biomass, thus addressing the research gap mentioned above and presenting commercial-scale applicability in terms of reactor designing, process control and optimization, and potential ways to upgrade existing models for higher accuracy.

“…We believe that the transfer of gaseous products of thermochemical decomposition from the zone of decomposition is carried out by filtration according to Darcy's law. With intensive thermal decomposition, the formation of additional channels of motion of the steam-gas mixture (SGM) due to the destruction of the porous framework is possible [9].…”

The paper provides an overview of the methods of utilization and processing of used wooden sleepers. The advantages and disadvantages of these methods are revealed. A mathematical description of the process of processing used sleepers by the method of fast pyrolysis is presented. We presented the results of theoretical and experimental studies of the volume of yield of thermal decomposition products in dependence on the process temperature, the hold-up time of the steam-gas mixture in the reaction zone, and the used wooden sleepers’ particle size.
