Research highlights

Ø  To raise diffusion questions in present gasification/combustion reaction kinetics measurements. A novel experimental method is applied to compare the diffusion and reaction characteristics in different particle swarms and TGA experiments. It is revealed that the diffusion conditions and temperature effects should be reconsidered in previous kinetics measurements of coal and petcoke gasification and combustion reactions. (Fuel 2019, 241: 973-984; AIChE J 2018, 64 (11): 4009-4018; Energy & Fuels 2019, 33 (4): 3057-3067.)

Ø  To raise a reaction mode of high ash content coal char gasification regarding to the residual carbon in slag. The novel reaction mode indicated that the increase of reaction temperature not only increase the reaction rate but also decrease the residual carbon in molten slag. (Energy & Fuels 2018, 32 (11): 11335-11343; Energy Fuel 2018, 32 (2): 1550-1557)
Ø  Investigation of the reaction kinetics of single petcoke particle at high temperatures. It is revealed that the reaction rate increased with the conversion. The pore development demonstrated the increase of surface area. What’s more, the pore development is related to the non-uniform distribution of reactive sites and the high graphitization of carbon. Reaction mode of single petcoke particle is developed.(in press, Chinese J. Chem. Eng. DOI: 10.1016/j.cjche.2019.02.025.)

Ø  Particle fluctuating motions induced by chemical reactions. A novel particle fluctuating motions induced by chemical reaction are investigated. The fluctuating velocity of particles increased with the combustion temperature. It is revealed that the irregular micro-structure of particles and nonuniform distribution of active sites on particle surface account for the particle fluctuations.
