Degradation Of Polycyclic Aromatic Hydrocarbons To Render Them Available For Biodegradation
Degradation Of Polycyclic Aromatic Hydrocarbons To Render Them Available For Biodegradation
US Patent:
8557565, Oct 15, 2013
Filed:
Mar 24, 2008
Appl. No.:
12/053980
Inventors:
David Wavrek - Salt Lake City UT, US

International Classification:
A62D 3/00, A62D 3/02, B09B 3/00, B09C 1/10, C02F 1/00, C02F 1/02, C02F 3/34, C10G 32/00
US Classification:
435262, 210600, 210767, 4352625, 435281
Abstract:
A method for the degradation of polycyclic aromatic compounds is disclosed that involves dissolving ozone in a bipolar solvent comprising a non-polar solvent in which is of sufficiently non-polar character to solubilized the polycyclic aromatic compounds, and a polar-water-compatible solvent which is fully miscible with the non-polar solvent to form a single phase with the non-polar solvent. The bipolar solvent with dissolved ozone is contacted with the polycyclic aromatic compounds to solubilize the polycyclic aromatic compounds and react the dissolved polycyclic aromatic compounds with the ozone to degrade the dissolved polycyclic aromatic compounds to oxygenated intermediates. The bipolar solvent is then mixed with sufficient water to form separate non-polar and polar phases, the non-polar phase comprising the non-polar solvent and the polar phase comprising the non-polar solvent and the oxygenated intermediates. The polar phase is then diluted and incubated with bacteria to biodegrade the oxygenated intermediates.
