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 ...

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 ...

Empirical Correlations for Biomass Pyrolysis Predictions
(EUBCE, 2010)
This work provides literature data on the characteristics of biomass pyrolysis. It is analyzed the behavior of product yields and properties on pyrolysis peak temperature dependence (within 200-1000ºC). Empirical relationships ...

A Tar Conversion Model for Fluidized Bed Biomass Gasifiers
(EUBCE, 2014)
A comprehensive tar conversion model for biomass gasification has not been developed up to date due to the great deal of processes involved, whose stoichiometry and kinetics are not well known. Therefore, simplified schemes ...

Gasification of Wastes in a Pilot Fluidized Bed Gasifier
(EUBCE, 2011)
A technical assessment of gasification of various wastes in fluidized bed was made by conducting test in a 100 kWth pilot plant. The reactor was operated under simulated autothermal and adiabatic conditions, thus allowing ...

Study of the Potential Ecological Risk of Heavy Metals in the Residue from Thermal Conversion of a Sewage Sludge
(EUBCE, 2018)
The thermal conversion of the sewage sludge by pyrolysis, gasification and combustion can be an attractive alternative because it reduces the volume of the residue and improve its properties for safe disposal. However, the ...
