The oxidation characteristics were discussed in combination with elemental analysis of water-soluble fractions. Results showed that reactive inorganics elements account for 30–40% in water-soluble fractions of the three agro-stalks and carbon was oxidized at two separate stages. Four stages were found during oxidation of water-soluble fractions – (1) devolatilisation of organics (100‒400 °C); (2) oxidation of char (400–650 °C); (3) oxidation of char with melting of salts or decomposition of carbonate (650–800 °C); (4) vaporization of KCl (800–1000 °C). This work provides a base study for an optimized design of combustion for agro-stalks and pharmaceutical waste.</p> <p> </p>}, number={3}, journal={Eurasian Chemico-Technological Journal}, author={Zhao, Rongkui and He, F. and Behrendt, F. and Cai, J. and Dieguez-Alonso, A. and Liu, Y.}, year={2021}, month={Nov.}, pages={181–189} }
