The pyrolysis process of the melon seed shell in nitrogen atmosphere was used as the research object by the thermal weight loss method. The main components of the shell of melon seeds are: hemicellulose, cellulose, and lignin. It is assumed that the shell of melon seeds is formed by three independent parallel reactions during the thermal decomposition process, respectively, genetic algorithm (GA) and nonlinear least squares method. (NLS), Gaussian fitting-genetic algorithm (GGA), establish the kinetic model of the pyrolysis of the melon seed shell, the kinetic parameters of melon seed shell during thermal decomposition were solved. The results show that the GGA algorithm has the minimum deviation between the simulated data and the experimental data and the best performance. The deviation is only 1.12%.
