dc.description.abstract | Accidental leakage and/or spillage of crude oil contaminates soil occurring during petroleum extraction, which can have harmful effects both on the environment and human beings. Therefore, petroleum contaminated soil needs to be effectively decontaminated. As a study of thermal remediation of petroleum-contaminated soil, a real soil sample contaminated with petroleum was pyrolyzed at different pyrolysis conditions. In particular, carbon dioxide (CO2) was used as the pyrolysis medium for effective thermal remediation of the petroleum-contaminated soil. At temperatures above 620 degrees C, pyrolytic gas evolution patterns obtained in CO2 condition were distinguishable from those obtained in N-2 condition; the generation of carbon monoxide (CO) was observed. The formation of CO at temperatures higher than 620 degrees C might be a clue about the role of CO2 in pyrolysis of the petroleum-contaminated soil in that CO2 helps form CO via reactions between CO2 and volatile species evolved from the petroleum hydrocarbons deposited on the soil during the pyrolysis. For further investigating the effect of CO2 on the pyrolysis, two-stage pyrolysis of the petroleum-contaminated soil was conducted. The CO evolution also occurred in the CO2 condition during the two-stage pyrolysis at >210 degrees C. The different compositions of pyrolytic oil obtained from the pyrolysis in N-2 and CO2 were identified in that the formation of polycyclic aromatic hydrocarbons was restricted by the consuming the source of carbon. The pyrolysis operated under CO2 atmosphere would be an effective decontamination method to treat petroleum-contaminated soil. | - |
