Research area 2: Production of bio-based activated carbons (AC) from residual biomass for wastewater treatment

Motivation and objectives

The overall objective of FB 2 is the production of high-quality AK from the IFBB press cakes  [FB 1] for the substitution of conventional AK based on fossil raw materials for the removal of micropollutants from biologically treated wastewater. The aim is to put residual biomass to a higher-value use, create regional value chains and generate ecologically sustainable regional activated carbons.

Methodical approach

The research approach in FB 2 includes a methodical recording of the pyrolysis and activation parameters that influence the quality of the biogenic activated carbons. For this purpose, a continuously operated laboratory pyrolysis reactor (PYREKA, Pyreg GmbH, Dörth, Germany) is used, which enables controlled and reproducible process settings.
