Laboratory Test: PAH research
Contact: Sebastian Meyer
Aim:
- Suitability assessment of analysis methods for the determination of the content of polycyclic aromatic hydrocarbons (PAH) in wood gasification residues.
- Evaluation of the efficiency of a thermal process for the reduction of the PAH content in gasification residues.
Method:
- Application of the analysis methods DIN 13877:A (extraction with acetone) and DIN 13877:B (Soxhlet extraction with toluene) for the determination of the PAH content in gasification residues.
- Analysis of the PAH content of untreated and thermally treated gasification residues.
Results:
- Analysis method DIN 13877:A (extraction with acetone) is not suitable for the determination of the PAH content in gasification residues. The application of the analysis method DIN 13877:B (Soxhlet extraction with toluene) is recommended for this purpose.
- The Σ EPA16 PAH content in gasification residues was reduced by up to 82% after thermal processing of the residues.
