TL;DR: In this article, a new criterion for determining the ash sintering temperature measured using the pressure-drop technique, based on the first-order and second-order derivatives of the pressure drop curves as a function of temperature, was proposed.

TL;DR: In this article, the effect of NO/NO2-sensitised oxidation of methane was experimentally studied with two fuel-lean mixtures, viz. 2.5% methane-in-air and 0.05% methane in-air mixtures at atmospheric pressure, over temperature ranges of 823-948 K, and 8731023 K, respectively.

TL;DR: In this article, a facile synthesis route for the production of mesoporous alumina (MA) with tuneable structural properties including BET surface area, pore volume and pore size was systematically investigated by tailoring the amount of template P123 used in the synthesis.

TL;DR: In this paper, the role of inherent inorganic matter and additives in low-lemperatures oxidation and spontaneous combustion of a Victorian brown coal was investigated and the relative effectiveness of the additives was determined by comparing their critical ambient temperatures with that of the acid-washed coal.

TL;DR: In this article, a study of mathematical modelling of pyrolysis of large coal particles using the distributed activation energy model is reported. But, the model is not suitable for the case of coal combustion and the model predictions are more sensitive to the kinetics than the heat transfer coefficient, which suggests that the pyroolysis of the large coal particle under conditions discussed in this paper is primarily kinetically controlled.
