摘要：Utilizing calcium aluminate (CaAlO) as a catalyst in lignocellulosic biomass pyrolysis offers dual advantages of cost saving and mitigating environmental pollution from industrial waste. This study employs kinetic analysis to validate the catalytic effect of CaAlO on biomass pyrolysis. Thermalgravimetric analysis of walnut shell pyrolysis was conducted, incorporating CaAlO, CaO, and Al2O3 additives to examine catalytic pyrolysis and gas release characteristics. The results reveal that CaAlO exhibits a catalytic effect similar to that of CaO and Al2O3, suggesting its potential as an effective catalyst. Activation energies obtained without additive and with CaAlO, CaO, and Al2O3 by Friedman method are 184, 178, 158, and 176 kJ·mol?1, while by Flynn–Wall–Ozawa (FWO) method are 186, 179, 160, 177 kJ·mol?1. Finally, DAEM analysis was performed, and the obtained parameters were successfully coupled into three-dimensional numerical simulation with some simplifications in the distributed activation energy model (DAEM) integration to reduce calculation cost, showing its potential applicability in biomass pyrolysis investigation. ? 2025 Chemical Industry and Engineering Society of China (CIESC) and Chemical Industry Press Co., Ltd.
