AI Article Synopsis
- The study examines the pyrolytic behavior of four lignocellulosic biomasses: avocado stone, Agave salmiana bagasse, cocoa shell, and α-cellulose.
- The analysis reveals that the order of pyrolytic decomposition is avocado stone < Agave bagasse < α-cellulose < cocoa shell, with differing reaction models for each material.
- Thermodynamic findings indicate that all biomasses have relatively low activation energy differences, suggesting easy pyrolysis, while avocado stone and Agave bagasse are near thermodynamic equilibrium, contrasting with the higher reactivity of cocoa shell and α-cellulose.
Article Abstract
This study focused on the analysis of the pyrolytic behavior of four lignocellulosic biomasses: avocado stone (AS), Agave salmiana bagasse (AB), cocoa shell (CS), and α-cellulose (CEL). According to the triplet kinetics analysis, the order of pyrolytic decomposition was AS < AB < CEL < CS. The AS was dominated by a second-order reaction, while AB followed a 2D diffusion-Valensi model. On the other hand, the pyrolysis of CS starts with an nth-order reaction and ends random nucleation model, and CEL was dominated by one-dimensional diffusion and first-order reaction. Thermodynamic studies reveal that the difference between the activation energy versus enthalpy change was<6.5 kJ/mol for all biomasses, thus showing the ease of pyrolysis reaction of these biomasses. Furthermore, the AS and AB showed that the reactions are close to thermodynamic equilibrium and stability, whereas CS and CEL indicated high reactivity.
