Evaluation of synergy during co-pyrolysis of torrefied sawdust, coal and paraffin. A kinetic and thermodynamic dataset

Abstract

This article aims to clarify and expand the information published in the article Evaluation of synergy during co-pyrolysis of torrefied sawdust, coal and paraffin. A kinetic and thermodynamic study, which evaluate kinetically and thermodynamically the existence of synergies during the co-pyrolysis of binary and ternary blends of coal, torrefied pine sawdust and paraffin. These materials were selected because they have been used before in the preparation of briquettes for the steel industry with good results. In order to facilitate the understanding and reproducibility of the main article, the following descriptions, dataset and figures have been provided: description and formulation of iso-conversional methods, some TGA curves and the standard deviation of the TG analysis, the activation energy of all the raw materials and their blends at different level of conversion using Friedman, Kissinger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO) methods, as well as, the linear plots for their calculations for the KAS and FWO models; also the thermodynamic parameters for pyrolysis of all the samples studied and the theoretical and experimental plots for prediction of solid state reaction mechanism using Criado method of several weights of paraffin are include.
