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 ...

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 . ...

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 ...

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 ...

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 ...
