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 ...

Technoeconomic assessment of potential processes for bio-Ethylene production
(Elsevier, 2013)
The use of biomass in the production of plastics can contribute to the depletion of greenhouse gas (GHG) emissions and secondarily to partially fulfill the growing demand for plastics expected in the near future. The aim ...

Tar conversion of biomass syngas in a downstream char bed
(Elsevier, 2020)
The catalytic conversion of biomass-derived tars over char during long tests (over 6 h) is studied. The syngas is generated in a steam-blown fluidized-bed gasifier employing wood pellets and conducted to a second tubular ...

Thermochemical biorefinery based on dimethyl ether as intermediate: Technoeconomic assessment
(Elsevier, 2013)
Thermochemical biorefinery based on dimethyl ether (DME) as an intermediate is studied. DME is converted into methyl acetate, which can either be hydrogenated to ethanol or sold as a co-product. Considering this option ...

Fluid dynamic analysis of dual fluidized bed gasifier for solar applications
(Elsevier B.V., 2021)
A hydrodynamic model of a dual fluidized bed gasifier (DFBG) is developed and its predictions are compared with measurements of solids flux and pressure profiles from a cold flow model (CFM). Then, the performance of a ...

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 ...
