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 .......
