In this study, a CFD-DEM reacting model featuring thermochemical sub-models is
developed for describing gas–solid reacting flow related to raceway dynamics and coke …

This study is a critical approach to the widespread use of the first order form of the Langmuir–
Hinshelwood (LH) equation for analyzing kinetics in heterogeneous photocatalytic …

Biomass can be converted into heat and power in fixed or fluidized fuel beds. Even though
the use of these combustion techniques is widespread, detailed knowledge of the …

CO 2 gasification with different coals and a petroleum coke from China were performed in a
thermogravimetric analyzer (TGA). Initial gasification rates of these sample chars were …

Staged gasification is an efficient method of converting biomass, producing a gas with a low
concentration of tar and with high process efficiency. This is achieved with reasonable …

Understanding apparent kinetics of single large fuel particle combustion is of significance to
the design and optimization of grate-firing and circulating fluidized bed boilers. Based on the …

Pressurized oxy-fuel combustion of coal in fluidized bed (FB) holds the potential to realize
low-cost CO 2 capture. However, the fundamental study in this manner is still rare due to the …

The gasification rate of char from olive tree pruning was measured in a fluidized bed at
temperatures between 760 and 900° C. Experiments were carried out using gas mixtures …

Most of the time char particles in commercial FB units encounter considerably lower oxygen
concentrations than that in the entrance, say between 2% and 10%, and the effects of the …

A high temperature stage microscope to investigate the temperature effect caused by
particle size on char gasification is applied in this study. Experiments were carried out with …
