Abstract

This paper reports results on recombination of pulsed CO2 laser dissociation products with Pt/Sn02 catalysts, and supporting studies in a surrogate laboratory catalyst reactor. The closed-cycle, pulsed CO2 laser has been continuously operated for 106 pulses with an overall power degradation of less than five percent. This operation was achieved by flowing the laser gas mixture through a 2% Pt/Sn02 catalyst bed. In the surrogate laboratory reactor experiments have been conducted to determine isotopic exchange with the catalyst when using rare-isotope gases. Some isotope exchange has been observed but a technique for minimizing such exchange has been demonstrated. The effects of catalyst pretreatment, catalyst sample weight, and catalyst composition and temperature on catalyst efficiency have also been determined.
