Modelo de reator pirolítico por indução eletromagnética

Abstract

The demand for alternative energy sources drives technological development in such a way that many fuels and energy conversion processes, previously thought to be inadequate or even unfeasible, are now competitors of traditional fuels and processes. Thus, biomass plays an important role, being considered a source of renewable energy. Biomass contributes a significant fraction of the Brazilian energy matrix. Several types of pyrolysis processes have been studied in recent years, with emphasis on the rapid biomass pyrolysis process to obtain bio-oil. Within this context, comparing the lines of research in the literature, many develop different configurations in relation to the type of bed used in the reactors or even with the aid of catalysis in the pyrolytic equipment, but using reactors with the same operating principles: resistance heating electricity, use of exhaust gases (gasification) or burning of fossil fuels, facilitating the control of heating rates. However, these models consume a lot of energy during their operation and also have limitations regarding their volume, since for large reactor volumes there is a decrease in the uniformity of heat transfer to the biomass that is more centralized in the reactor bed. It is characteristic of chemical engineering to use multidisciplinary concepts to obtain results in processes and improvement in general, for this reason in the present work, a model almost never mentioned in the literature for the operation of a pyrolytic reactor, through an Inductive / Capacitive (LC) circuit oscillatory with development of a reactor project to perform pyrolysis through electromagnetic induction. This project aims to compare the efficiency and energy consumption between the two types of reactors (and verify their operating advantages and disadvantages in relation to the model used in the laboratory, Electrical resistance, electromagnetic induction), and describe their results.
