Additionally, the specific surface area was not considered in the correlations because it was not the main factor affecting the reactivity. The isothermal and non-isothermal gasification reactivities of coal char gradually decreased with the increase of the pyrolysis temperature to some extent. However, I_D1/I_G could act as a rough indicator for evaluating the characteristic temperatures of chars. It was also revealed that the reaction rate was controlled by various chemical structural factors at different stages. Hence, the correlations based on the chemical structure parameters by combining X-ray diffraction and Raman spectroscopy showed credibility on the prediction of char characteristic temperatures as the critical factor varied with the gasification stage.]]> Tue 08 Mar 2022 11:08:23 AEDT ]]> Char reactivity and kinetics based on the dynamic char structure during gasification by CO2 https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38273 Fri 20 Aug 2021 14:01:38 AEST ]]>
