Comprehensive Evaluation of Catalytic Hydroreduction and Nonthermal Plasma as Alternative Technologies for Detoxification of Chemical Wastes

摘要

The longevity of the catalytic hydrotreatment of chloroethyl ethyl sulfide has been demonstrated over Ni-Mo/AC and Pt/MZ391 catalysts. 99.996% to 99.999% destruction efficiency was achieved. The results suggest that catalytic Hydrotreatment is a promising technology for the detoxification of mustard gas. The RF non-thermal plasma technology has been successfully demonstrated to be effective for the removal and destruction of DNT, TNT, RDX, and Comp B on shell surfaces. Destruction and removal efficiency above 99.99% was achieved for most of the tests. N2, CO2, and H2O are the major decontamination products with small amounts of NO(sub x), mainly NO, generated. The process is economical and environmentally benign. It is estimated that the current nondestructive decontamination process can be scaled up to decontaminate shell casings at an operating cost of less than $30/metric ton.
