New project about carbonization processes [29.11.2013]

The new project "Analysis and assessment of different carbonization processes for utilizing biogenic residues under technological and economic aspects" has started.

Carbonization is considered as a possibility to convert biogenic residues into biochar for a more efficient energetic or material use. At present, various carbonization processes are under development, which differ significantly regarding the selected process conditions. Within this project, Biomass Steam Processing (BSP), Hydrothermal Carbonization (HTC), slow Pyrolysis as well as a related process, Torrefaction, should be examined more closely.

The project aims at analyzing and assessing the selected carbonization processes for biogenic residues under technological and economic aspects. As a first step, all biogenic residues in Baden-Württemberg, which are relevant for these processes, should be identified. Then the carbonization processes are evaluated using both the assessment of literature data and pilot plant scale experiments for the conversion of biogenic residues into biochar by steaming treatment (BSP process). On this basis the different carbonization processes are compared with the help of their technical and economic parameters. This includes the consideration of aspects and factors relevant for the decision on the production site and plant capacity.

The project is carried out in collaboration with the Engler-Bunte-Institute / Division of Combustion Technology.
