N2 - Polynuclear aromatic hydrocarbons (PAHs) are very toxic compounds and very stable in the natural environment. Permeable reactive barriers, which employ zero-valent metals (ZVMs) as the reactive material, have been used to treat halogenated organic compounds in contaminated soil and ground water. ZVMs are successfully used on reductive dechlorination, but their reactivities are not enough to reduce PAHs. In general, aromatic hydrocarbons are known to be more toxic than corresponding alicyclic compounds of similar structures. Reduction of naphthalene was conducted using zero-valent bimetals, Pd/alumina catalyst and hydrogen in an aqueous system. One of the two rings of naphthalene was reduced to produce 1,2,3,4-tetrahydronaphthalene, at ambient temperature with Pd/Fe. However, the produced 1,2,3,4-tetrahydronaphthalene was not further reduced with Pd/Fe after two months of experiments. By increasing the hydrogen pressure up to 7 atm and temperature up to 120°C, 1,2,3,4-tetrahydronaphthalene was reduced to cis- and trans-decahydronaphthalene with about one day of half-life.
