Burn the contaminants! Investigating the fate of PAHs in pyrolysis
- Beschreibung
Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds made up of multiple fused aromatic rings. PAHs are widely recognized for their environmental persistence toxicity and pose risks to human health and ecosystems. They are commonly found in air, water, and soil, accumulating in these environments. For solid samples contaminated with PAHs, one strategy to remove them could be the thermal treatment of the solid, using pyrolysis.
In this project, you would study the fate of PAHs during the pyrolysis of contaminated solids. You will explore how these toxic compounds are degraded or formed when pyrolyzed. The goal is to ensure that PAHs are minimized or eliminated during this waste treatment. Special attention will be given to the effect of different temperatures on developing or removing such substances.
The working plan is divided into three main tasks:
- What is pyrolysis and how to do it? You will perform the pyrolysis of the solid contaminated with PAHs, selecting different pyrolysis temperatures.
- How to analyze PAHs in pyrolyzed solids? You will prepare pyrolyzed solid samples for PAHs analysis at an external laboratory, with the opportunity to visit the lab, see the equipments and understand the methodology.
- What is the best pyrolysis temperature to remove PAHs? Based on the obtained data, you will analyze the results, identify trends, and formulate hypothesis regarding the fate of PAHs during pyrolysis.
