| Summary: | Title screen The need to develop resource-efficient solutions for thermal processing of organic raw materials to reduce the environmental impact causes the increasing popularity of microwave pyrolysis. However, in spite of its many advantages, it is still relevant to find the ways for enhancing the process energy efficiency by reducing the processing time. This work reveals the influence of the liquid pyrolysis products on the initiation time and development of the microwave pyrolysis process for 8 different types of organic raw materials with various geological ages and demonstrates how these parameters affect the total energy consumption. By means of experimental and analytical studies, the numerical dependence between the process duration and yield of liquid pyrolysis products is found in the form of a corresponding equation. The revealed dependence is applied to develop an approach to reduce energy consumption of microwave pyrolysis by creating mixed compositions containing organic raw materials with different liquid products yields, where one of the components acts as an intensifying additive. On the example of manure and pine nutshells in mixtures with hard coal, it is demonstrated that the increase in the mass fraction of the additive from 10 to 50 % shortens process energy costs by 2.6–7.3 % and 10–32 %, respectively. These results allow predicting and choosing optimal compositions of organic fuels to decrease their processing time under microwave heating conditions that will significantly reduce the energy costs for microwave pyrolysis, costs of secondary pyrolysis products, and greenhouse gas emissions Текстовый файл AM_Agreement |
