“…Also, the third disc (Pt C Pd/ -Al 2 O 3 ) has been prepared via two successive impregnations; the first using Pd (NO 3 ) 2 solution and the second one used H 2 PtCl 6 with the requisite quantity of the metal precursor (10 4 gm of Pt and 10 4 gm of Pd). More details have been given elsewhere (Deriase et al, 2012).…”

“…The objective of this work is to extend the previous work (Deriase et al, 2012) to focus on studying the factors affecting carbon monoxide emissions by predicting a model equation used to establish the influence of both the axial mean temperature distribution along the catalytic flames and the axial distance over the current catalytic disc burners of Pt, Pd, and (Pt C Pd) supported on -Al 2 O 3 disc to give a new insight into their simultaneous effects on the volumetric percentage of CO emissions. Multiple non-linear regression approach has been applied.…”

“…The catalytic combustion model was for a mixture of CO, NO, and air using the stagnation-point flow geometry. The proposed chemical reaction mechanism was able to reduce NO and oxidation of CO. Deriase et al (2012) investigated experimentally and numerically the catalytic combustion of gaseous turbulent diffusion flames operating over noble metal burners containing Pt, Pd, and (Pt C Pd) supported on -Al 2 O 3 . These catalytic flames have proved to be highly stable and have highly thermal distribution and lower values of CO and NO.…”

Performance of a combustion system is often constrained by limits of pollutant emissions such as CO. Catalytic combustion over noble metals promotes efficient combustion with minimum pollutant formation. In this study, the volumetric percentage of carbon-monoxide distribution along the catalytic flames operating over noble metal disc burners Pt, Pd, and (Pt C Pd) supported on -Al 2 O 3 discs are analyzed through non-linear exponential model function. The numerical prediction correlates the response variable (CO %) with two explanatory (independent) variables: the axial mean temperature and axial distances over each catalytic burner simultaneously. The fitting process indicates high adequacy matching with the experimental data. The response surface construction, with corresponding contour maps, has been established to visually analyze the proposed model equations and to fully identify the extent of the estimated relationship in the combustion domain. These constructions reveal clearly that the response variable (CO %) is mainly dependant on the axial mean temperature distribution and slightly on the axial distances along the catalytic flames and also indicate the effectiveness of the three noble disc burners in reducing CO emissions along the catalytic flames minimizing the environmental pollution.
