MODEL OF PYROLYSIS OF ORGANIC MATTERS OF VARIABLE COMPOSITION

Abstract

The organization of the process of slow pyrolysis of organic substances, in the general case of unknown and variable composition, is considered. The relevance of the work is determined by considering the possibility of using various organic waste without preliminary sorting and drying to obtain secondary energy resources of controlled composition. The novelty of the work is due to the development of a model of the method of controlled pyrolysis or gasification of organic substances with a minimum amount of solid residues with a maximum calorific value of the resulting mixture of combustible gases. The process scheme proposed for consideration is based on the organization of the associated flow of feedstock and reaction products. As a result, the resulting carbon dioxide and water vapor are used as additional oxidizing agents. As a result, the carbonaceous residue decreases with a simultaneous increase in the composition of the mixture of gaseous products of carbon monoxide and hydrogen. A real-time monitoring scheme for the composition of the feedstock during pyrolysis (gasification) is proposed. Knowing the composition allows you to manage the process of its processing with the aim of: a) organizing the optimal gasification process in terms of maximizing the quantity and energy value of the mixture of gaseous reaction products; b) manage the flow of processed feedstock in order to produce the quantity of product gas required at each moment of time.
