Ignition behavior of single coal particle in a fluidized bed under O2/CO2 and O2/N2 atmospheres: A combination of visual image and particle temperature
(Elsevier, 2014)
Single coal particle ignition behavior was studied in a two-dimensional (200 mm × 20 mm × 400 mm) fluidized bed under O2/N2 and O2/CO2 atmosphere with O2 volume concentration in the range of 0–40%, by a combination of ...

Modeling biomass char gasification kinetics for improving prediction of carbon conversion in a fluidized bed gasifier
(Elsevier, 2014)
Gasification of biomass in a fluidized bed (FB) was modeled based on kinetic data obtained from previously conducted thermogravimetric analysis. The thermogravimetric analysis experiments were designed to closely resemble ...

Effect of CO2 on oxy-fuel combustion of coal-char particles in a fluidized bed: Modeling and comparison with the conventional mode of combustion
(Elsevier, 2016)
A char combustion model is developed to study the effect of CO2 on the combustion of coarse char particles under oxy-fuel conditions in a fluidized bed (FB). It is a transient one-dimensional model, taking into account the ...

The effects of calcium and potassium on CO2 gasification of birch wood in a fluidized bed
(Elsevier, 2017)
Birch wood was leached of its naturally occurring ash forming elements and doped with three concentrations of calcium or potassium before being gasified in a laboratory bubbling fluidized bed reactor. The wood samples were ...

Devolatilization of a single fuel particle in a fluidized bed under oxy-combustion conditions. Part B: Modeling and comparison with measurements
(Elsevier, 2015)
A detailed one-dimensional transient model is developed to describe the conversion of a single fuel particle in O2/N2 and O2/CO2 atmospheres in a fluidized bed (FB). The model takes into account the main relevant phenomena ...

Kinetics of H₂S removal using alkaline residue as in-bed sorbent in fluidized bed gasification of biomass and wastes
(Elsevier, 2023-05)
The use of alkaline residue from the acetylene industry (carbide slag, CS) as in-bed sorbent to remove H₂S from syngas from biomass/waste fluidized bed (FB) gasification was investigated. Measurements were conducted in a ...
