Book Description
A flow trough type catalytic reactor system was adequately modified for NO related catalytic and adsorption measurements, including the on-line connection of a digital chemiluminescent NO-NO(subscript x) analyzer to the reactor outlet system. Moreover, we have largely completed the installation of an FTIR coupled catalytic system containing a HTEC cell for high temperature DRIFT studies. Three different barium cuprate samples, Ba2CuO3, BaCuO2, and Ba2Cu3O5 were synthesized and characterized by powder XRD for catalytic tests. Prior to catalytic studies over these cuprates, a new, liquid indium based supported molten metal catalyst (In-SMMC) was tested in the reduction of NO by various reductants. In the presence of excess O2 and H2O, the In-SMMC proved to be more active for the selective catalytic reduction (SCR) of NO to N2 by ethanol than most other catalysts. Using C1-C3 alcohols as reductants, self sustained periodic oscillations observed in the NO(subscript x) concentrations of reactor effluents indicated the first time that radical intermediates can be involved in the SCR of NO by alcohols. Further, In-SMMC is the only effective and water tolerant SCR catalyst reported thus far which contains SiO2 support. Thus, this novel catalyst opens up a promising new alternative for developing an effective and durable catalyst for NO(subscript x) abatement in stack emission.

Book Description
This project will investigate a suitable catalyst system for the direct NO decomposition, for post-combustion NO. control. The proposed process will not use a reductant, such as ammonia in case of Selective Catalytic Reduction (SCR) process for catalytic reduction of NO(subscript x) to nitrogen. This is a simplified process basically involving passing the flue gas through a catalytic converter, thus avoiding problems generally associated with the commercial Selective Catalytic Reduction (SCR) process, namely high operating cost, ammonia slip, and potential N20 emissions. A brief description of the proposed work is as follows: Catalysts will be prepared by incorporating metal cations into zeolite supports according to ion exchange procedures widely used in preparation of metal/zeolite catalysts. Zeolites will be modified to improve catalytic activity, by blocking ion exchange sites in the small pores of zeolites with promoter cations of high valence. The catalysts of primary interest include copper (Cu), palladium (Pd), platinum (Pt), silver (Ag), and nickel (Ni) exchanged zeolites.
