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 ...

The Effect of Temperature and Steam Concentration on the Yields of Tar Compounds in Fluidized Bed Pyrolysis
(EUBCE, 2011)
The effect of temperature and steam concentration on the yields of different tar compounds was investigated. Wood pellets and dried sewage sludge spheres (DSS) were pyrolyzed in a fluidized bed reactor in the temperature ...

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 ...

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 ...

Devolatilization of two agricultural residues in fluidized bed: product distribution and influence of fluidization agent
(EUBCE, 2011)
Devolatilization of two agricultural residues; corn stover and a solid by-product from enzymatic hydrolysis of biomass (cake), was carried out in a fluidized bed at temperatures between 750 and 900 ºC. The distribution of ...

Gasification kinetics of char from olive tree pruning with CO2 and stema in fluidized bed
(EUBCE, 2013)
Kinetics of gasification of char from olive tree pruning was measured in a fluidized bed at temperatures between 760 and 900 ºC. Experiments were carried out using H2ON2 and CO2N2 mixtures to measure the rates of the ...

Gasification of Char from Dried Sewage Sludge with Steam and CO2 in Fluidized Bed
(EUBCE, 2010)
Kinetics of gasification of char obtained from dried sewage sludge (DSS) with steam and CO2 have been measured in a laboratory fluidized bed (FB) reactor at temperatures between 800 and 950 ºC with steam and CO2. Char was ...
