Abstract:

During the final year of this program, novel catalysts were developed and tested for the destruction of the CWA simulant, DMMP. The breakthrough result of over 100 hours of continuous operation at a nominal conversion of 99.9 was demonstrated, with no apparent poisoning of the catalyst Products and spent catalysts were characterized using IC, FTIR, XPS, BET, and GC techniques and mechanistic pathways were postulated. In addition, a model was used to design a photocatalytic reactor for the destruction of DMMP on titania. A prototype reactor was constructed and the conversion efficiency was measured to be in reasonable agreement with the models prediction. Reactor size requirements were calculated for optimum destruction of DMMP.
