International workshop on 

Development of torrefaction technologies and
impacts on global bioenergy use and
international bioenergy trade

Friday , 17 January 2014, 14.00 - 18.10

Central European Biomass Conference (CEBC), Stadhalle, Graz, Austria

Task 32:
Biomass combustion and co-firing

Task 40:
Sustainable International Bioenergy trade

Workshop rationale and aim

Torrefaction is an interesting pre-treatment technology for biomass before pelletisation and/or combustion. It is a thermo-chemical process for the upgrading of biomass that is usually run at temperatures ranging from 250 to more than 300°C under the exclusion of oxygen and at ambient pressure.

Task 32, in co-operation with Task 40 and the EU SECTOR project organised a workshop on torrefaction as a parallel session within the Central European Biomass Conference 2014 in Graz, Austria.

The presentations can be downloaded below. A summary of the presentations and conclusions of the round table discussion is available here.
