FICFB Gasification Process |
Overview
of the FICFB (Fast Internally Circulating Fluidized Bed)
gasification process, development, components and flow
concepts. Development process and summary
gasification results. Authors: Hofbauer, Veronik,
Flecl, Rauch, Mackinger, Fercher. |
|
Gasifier efficiency
|
Summary
of experience with FICFB gasifier efficiency, main
parameters affecting yield,
LHV 10-14 MJ/m3/s. Authors:

|
Gasification plants in
Austria |
Review of
two Austrian gasification demonstration plants and their
performance/history. FICFB plant at Güssing
compared with twin-fire downdraft system in Neustadt;
the former is a larger community approach, the latter is
a smaller system and approach. Authors:
Bolhàr-Nordenkampf, Hofbauer. |
|
Gasifier future development |
Development of the FICFB reactor to adapt to flexible
feedstocks (e.g. MSW, sewage sludge, hog fuel).
System summary. Experience with Güssing and
Oberwart plants. Comment on other systems under
development; suitability of a modified FICFB system.
Development at the Technical University of Vienna.
Possible limitations needing management in any move to
developing flex-fuel systems. Authors:
Pfeifer, Schmid, Pröll, Hofbauer. |
|
Plastics gasification
review |
Since
both light and heavy plastics make up the majority of
the fossil component of MSW, understanding the impact of
this on gasification is important for MSW processing.
Concludes that plastics can be gasified but with limits
on upper content threshold before supplementary gas is
required to augment operations. Authors: Wilk,
Kern, Kitzler, Koppatz, Schmidt and Hofbauer. |
|
Plastics gasification
review |
Review of
plastics gasification. Comment on high quality
stable syngas composition. References other
studies. Concludes that plastics can be gasified,
fluidized beds being most promising. Addresses tar
levels using catalysts, reactor temperature etc.
Authors: Arena, Zaccariello and Mastellone,
University of Naples. |
|
Integrated drying using
gasification |
Integrated Combine Cycle gasification using BICBF
gasifier (HRI), to contribute to feedstock drying.
Impact of moisture and carbon content. Different
drying options. Authors: Bolhàr-Nordenkampf,
Hofbauer. |
|
Electrical generation from
Syngas
|
Use of
FIFCB gasifier syngas to power electrical generation
using a gas-hybrid system fuel cell, due to the high
yield and stable output of the FICFB system at Güssing,
Austria. Chemical process and performance summary,
impact on heat recovery cycle & efficiency.
Authors: Proell, Aichernig, Rauch, Hofbauer. |
|
Güssing demonstration plant
status |
Review of
the FICFB plant at Gussing, Austria to end 2004, by the

on system suitability for further development including
Fischer-Tropsch diesel. Authors: Rauch,
Hofbauer, Bosch, Siefert, Aichernig, Tremmel,
Voigtlaender, Koch, Lehner. |
|
Hydrogen-rich syngas study |
Original
analysis of the production of hydrogen-rich syngas from
the original pilot plant, 2001. Documentation of
process, development and aspects affecting performance
and management. Role in catalytic conversion
processes. Product gas composition/analysis.
Experience with start-up system. Authors:
Hofbauer, Rauch. |
|
Polygeneration at Oberwart |
Polygeneration at Oberwart gasifier, Austria (heat,
electricity, hydrogen for biofuels). Impact of
trade-off between hydrogen purity and overall yield.
Impact on polygeneration. Authors: Mayer,
Makaruk, Diaz, Bosch, Miltner, Harasek, Hofbauer. |

within the FICFB process. Impact of gas cleaning
using catalysts. Authors: Pfeifer, Rauch, Hofbauer. |
|
Water consumption in the
FICFB gasifier |
Analysis and discussion of the use of water and steam in
the FICFB process and system. Exclusion of
nitrogen. Relationship of steam, feedstock/fuel
and temperature in reducing tar generation.
Extended pilot project analysis. Authors:

designs for FICFB to improve in situ conversion of
hydrocarbons (i.e. relevant for MSW). Reduction or
avoidance of volatile hydrocarbons by developing a Dual
FICFB system. Authors: Schmid, Pfeifer, Kitzler,
Pröll, Hofbauer. |
