Booming oil exploration activities in Nigeria have constantly caused environmental pollution. Over three million barrels of crude oil spilled into the Niger Delta region. Thermal remediation technologies are established for treating oil contaminated soil but suffer from high energy costs. The aim of the research is to applying microwave pyrolysis for contaminated soils and draw comparisons with traditional pyrolysis methods. The specific objectives are to optimise processing parameters in microwave pyrolysis, to characterise the oils released and compare the energy consumption with microwave pyrolysis. In particular, the impact of soil composition and moisture content on the removal of crude oil in microwave pyrolysis are being determined. It has been shown for the first time that oil removal comparable to traditional pyrolysis can be achieved for soils rich in clay.
