Mathematical Modeling of Conversion CO To CO2 in Batch Mode CO2 Laser System


The oxidation of carbon monoxide CO over supported noble metal catalyst is animportant part of the catalytic control in sealed-off TEA CO2 laser system. In this model,the activities of supported noble metal catalysts (Pt/Al2O3 and Pd/Al2O3) separately inremoval CO as CO2 gas phase are studied at isothermal conditions. A batch equation is usedin this model to study the effect of reaction rate parameter k (sec −1 ) on conversion processesat contact time t =2500 (sec) and to control the path of gases from and the reactor cavity toindicate the effect of contact time. These results are confirming that the dissociated gases areremoved by using catalysts to regenerate CO2 molecules during the electrical discharge.
