To address the issues of cities being overwhelmed by the waste and energy crisis, the pyrolysis of municipal solid waste (MSW), oil shale (OS) and their blends was investigated using a thermogravimetric simultaneous thermal analyzer in this study. The experimental research was conducted to investigate the thermal behavior and kinetic parameters of the different blending ratios of MSW and OS, to better utilize these intractable resources, observing whether there is a synergistic effect and trying to find the optimal process conditions. The Ozawa–Flynn–Wall method and the Kissinger–Akahira–Sunose method were used to calculate the activation energy at four different heating rates. The existence of interactions between MSW and OS was confirmed by comparing the experimental thermogravimetric and derivative thermogravimetric curves with the calculated ones. The findings of the thermogravimetric analysis, the calculation of theoretical and experimental curves, and kinetic analysis confirmed the interaction between the components and that the optimal blending ratio is 30% MSW and 70% OS. The optimality results in a relatively smaller activation energy (Eave = 115 kJ/mol), better comprehensive pyrolysis characteristics, and a more beneficial mutual effect.
