Techno-Economical Analysis for a 3 MWth Gasification Plant Revamping: Use of Enriched Air and Steam as Gasifying Agent
(2010)
An assessment of the revamping of a 3 MWth atmosphericpressure bubbling fluidized bed biomass gasifier was made in order to study the technoeconomical viability of changing the gasifying agent from air to a mixture of ...

Influence of the Stoichiometric Ratio on Tar Composition during Fluidized Bed Gasification
(EUBCE, 2017)
Fluidized bed gasification is a promising technology for the energetic valorization of biomass and wastes. However the presence of heavy tars limits the use of the gas to applications where the gas is not cooled. Several ...

Investigation of Tar Properties for Tar Removal by Scrubbing
(EUBCE, 2010)
A new concept to remove tar by scrubbing from biomass gasification gas is investigated. The concept is based on a system capable to remove the tars in two sequential stages: heavy tars are removed in a first hot absorber ...

Heavy Metals Partitioning during Thermal Conversion of Sewage Sludge in a Fluidized Bed under Conditions Relevant for Pyrolysis and Gasification
(EUBCE, 2017)
There is a growing concern on the final disposal of urban organic wastes, such as municipal solid waste (MSW) and sewage sludge (SS), since they constitute an available energy and material source currently not efficiently ...

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 ...

Biomass oxy-gasification integrated into a coal oxy-boiler.
(EUBCE, 2011)
A biomass gasifier coupled to an oxycombustion boiler is an attractive concept, enabling simultaneous production of syngas of medium heating value and carbon “capture” from concentrated CO2 taken from the fluegas of an ...

Experimental Investigation of Olive Tree Pruning Gasification in a Bench-Scale Fluidized Bed
(EUBCE, 2016)
Olive tree pruning was gasified in a laboratory fluidized bed reactor using air as gasifying agent. Different operating temperatures (800, 850 and 900 ºC) and equivalence ratios (ER) (0.12-0.35) were tested and additional ...

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 ...

Biofuel production from supercritical water gasification of sustainable biomass
(Elsevier, 2022-05)
A review of biofuel production from supercritical water gasification (SCWG) of sustainable biomass has been performed, mainly organic waste, following a critical thinking in this field of knowledge. Thus, sub- and super- ...
