Description:

Chlorinated aliphatic and aromatic liquid wastes are highly toxic and are difficult to destroy by incineration. In particular, incomplete thermal incineration of polychlorinated biphenyls can lead to the formation of highly toxic polychlorinated dioxins and furans. To minimize formation of these toxic byproducts, incinerators are generally grossly overdesigned, leading to increased construction and operating costs.

An alternative to the incineration of chlorinated organics is detoxification. Low temperature catalytic hydrogenolysis converts Chlorinated hydrocarbons (CHCs) to much more benign hydrocarbons and HCl. The hydrocarbon and HCl can be recycled or the hydrocarbon can be burned for its fuel value. Catalytic hydrogenolysis is typically performed by platinum group metals, however, it is well known that HCl is a strong poison for platinum group metals and rapidly deactivates the catalysts. Therefore, TDA Research proposes to develop high surface area non-precious metal catalysts for the catalytic hydrogenolysis of CHCs. Previous work has shown that the proposed materials are good hydrogenolysis catalysts and are resistant to the poisons that degrade platinum-group catalysts.
