ABSTRACT:
A method of removal of hydrocarbons from soils using solids-loaded polymer foam. A first step involves providing a solids-loaded polymer foam consisting of an open-celled polymer foam matrix with zeolite dispersed and bound throughout the foam matrix. A second step involves mixing soils containing hydrocarbons, solids-loaded polymer and water. It has been found that hydrocarbons are adsorbed by the solids-loaded polymer foam. The order of mixing can be altered to suit particular applications. A recovery step can be added to recover the hydrocarbons from the solids-loaded polymer foam.
