| Petroleum coke was used to remove high molecular weight hydrocarbons from
Sucarnoochee soil, a fine-sized high-organic soil. Fine coke in slurry form was blended
with synthetically contaminated soil (Sucarnoochee soil and Hunt Crude Oil in an 85:15
weight ratio), and agglomerates were removed in a standard flotation cell. oil in the
remediated soil was reduced from the original 15.0% to approximately 0.5% by a one-step
process and to approximately 0.2% by a two step process. Oil removal of approximately
98.0% was obtained. The results obtained with the coke process were comparable to an
identical soil remediation process using fine coal. Keywords:
