Thermochemical biorefinery based on dimethyl ether as intermediate: Technoeconomic assessment
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 ...
Application of biomass gasification fly ash for brick manufacturing
Biomass gasification technology offers an attractive way to use low-grade fuels in energy production with high efficiency and low environmental impact. However, an issue calling for further development is the volume and ...
Modeling biomass char gasification kinetics for improving prediction of carbon conversion in a fluidized bed gasifier
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 ...
The effects of calcium and potassium on CO2 gasification of birch wood in a fluidized bed
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 ...
Tar conversion of biomass syngas in a downstream char bed
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 ...
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 ...
