Determinación de la cinética química del proceso de gasificación de briquetas provenientes de cáscara papa y tusa de maíz mediante análisis termogravimétrico

Abstract

The demand for fuels, the depletion and prices of fossil fuels, and the generation of significant amounts of organic waste from industries and the population are some of the reasons for the search and determination of the viability of energy alternatives through garbage. Therefore, this research aimed to determine the chemical kinetics of the gasification process of briquettes from potato peel and corncob by thermogravimetric analysis. The methodology had a qualitative and quantitative approach, a longitudinal experimental design using several variables over time, documentary and empirical research, and operating methods, techniques, and instruments such as elemental analysis, thermogravimetric, and kinetic modeling were also applied. Data was used as a methodology to obtain on the annual production of residues of potato husk and corncob and the biomass gasification process that allowed the creation of models with kinetic parameters: activation energy (E) and pre-exponential factor (A) and their respective adjustment to minimize the error between the experimental and calculated values. Therefore, the chemical kinetics of the gasification process of briquettes from potato peel and corncob were determined by thermogravimetric analysis with two different models, in addition to the feasibility of using and exploiting these residues.
