The dual-competitive parallel kinetic model with an efficient optimization algorithm for describing polymer pyrolysis accurately

Thermal analysis is an important method to evaluate the thermal stability of polymer materials; however, efficiently describing complex pyrolysis process polymers remains a great challenge. In this paper, new dual-competitive parallel-reaction kinetics model proposed for thermogravimetric lines material processes. method, peak analysis, reaction form, and parallel mechanism are combined build kinetic resin pyrolysis. The includes peak-determined components, each component divided into two competitive reactions. reactions obtained by conducting initial subsequent global parameter optimization. rebuilt line via agrees well with experimental data, few compositions low computational cost. addition, synthetic natural biomass also successfully described high accuracy. This work provides updated accurately, which may advance in developing behavior.
