Journal ArticleDOI
Biomass pyrolysis kinetics: A comparative critical review with relevant agricultural residue case studies
TL;DR: A critical review of kinetic models and mathematical approximations currently employed in solid state thermal analysis is provided and analysis of thermal decomposition data obtained from two agricultural residues, nutshells and sugarcane bagasse reveals the inherent difficulty and risks involved in modeling heterogeneous reaction systems.
Journal ArticleDOI
Analysis of aluminium based alloys by calorimetry: quantitative analysis of reactions and reaction kinetics
TL;DR: Differential scanning calorimetry has been applied extensively to the analysis of light metals, especially Al-based alloys as discussed by the authors, and is used for analysis of solid state reactions, such as precipitation, homogenisation, devitrivication and recrystallisation.
Journal ArticleDOI
Combustion characteristics of Malaysian oil palm biomass, sub-bituminous coal and their respective blends via thermogravimetric analysis (TGA).
TL;DR: The thermogravimetric analysis demonstrated that the EFB and PKS evolved additional peak besides drying, devolatilisation and char oxidation steps during combustion, which resulted in highest activation energy during combustion of PKS followed by PMF, E FB and MB coal.
Journal ArticleDOI
Combined kinetic analysis of solid-state reactions: a powerful tool for the simultaneous determination of kinetic parameters and the kinetic model without previous assumptions on the reaction mechanism.
TL;DR: A modification in the combined kinetic analysis is proposed by using an empirical equation that fits every f(alpha) of the ideal kinetic models most extensively used in the literature and even their deviations produced by particle size distributions or heterogeneities in particle morphologies.
Journal ArticleDOI
Advantages of Combined Kinetic Analysis of Experimental Data Obtained under Any Heating Profile
TL;DR: In this paper, the combined analysis of experimental data by means of the logarithmic expression of the general differential equation is used for the determination of the kinetic parameters of solid-state reactions.

Kinetics of Phase Change. I General Theory
TL;DR: In this paper, the theory of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment.
Journal ArticleDOI
Kinetics of Phase Change. II Transformation‐Time Relations for Random Distribution of Nuclei
TL;DR: In this article, a relation between the actual transformed volume V and a related extended volume V1 ex is derived upon statistical considerations, and a rough approximation to this relation is shown to lead, under the proper conditions, to the empirical formula of Austin and Rickett.
Journal ArticleDOI
A New Method of Analyzing Thermogravimetric Data
TL;DR: In this paper, a new method of obtaining the kinetic parameters from thermogravimetric curves has been proposed, which is simple and applicable to reactions which can not be analyzed by other methods.
Journal ArticleDOI
Granulation, Phase Change, and Microstructure Kinetics of Phase Change. III
TL;DR: In this paper, a comprehensive description of the phenomena of phase change may be summarized in Phase Change, Grain Number and Microstructure Formulas or Diagrams, giving, respectively, the transformed volume, grain, and microstructure densities as a function of time, temperature, and other variables.
