Pyro-thermal-kinetic

This repo contains matlab implementations of some commonly used algorithms in pyrolysis or gasification experiments.

Part of the codes and their modifications were used in papers:

• Kinetics and mechanism of CO2 gasification of coal catalyzed by Na2CO3, FeCO3 and Na2CO3–FeCO3

• Predicting kinetic triplets using a 1d convolutional neural network

• Characterization of Powder River Basin coal pyrolysis with cost-effective and environmentally-friendly composite Na-Fe catalysts in a thermogravimetric analyzer and a fixed-bed reactor

• Some Optional Methods of Activation Energy Determination on Pyrolysis

Currently, functions are not well structured and organised. More descriptions and usage examples will be added .......

Some Key Functions

• preprocess.m: Preprocess data obtained from experiement equipments.
• batch_E.m: Activation energy calculation from different methods.
• daem_point_fit.m: DAEM method in a point-wise style.
• daem_distribution.m: Make plots for decomposed composnents of f(E) from DAEM method.
• daem_simulate.m: Make curves simulated with parameters calculated from DAEM method.
• analysis_plots.m: Making plots for general thermal dynamic variables.
• masterG_modified.m: Making masterplots for deciding reaction functions.
