LGP catalytic combustion study of porous burner containing perovskite.
Combustion in porous media has been a promising alternative for the production of thermal energy making the process more efficient and low polluting. The Liquefied Petroleum Gas (LPG) combustion in a porous burner catalytically enhanced by perovskites (LaFe0,6Co0,4O3 and LaCoO3) impregnated in alumina...

| Resumo: | Combustion in porous media has been a promising alternative for the production of thermal energy making the process more efficient and low polluting. The Liquefied Petroleum Gas (LPG) combustion in a porous burner catalytically enhanced by perovskites (LaFe0,6Co0,4O3 and LaCoO3) impregnated in alumina spheres (Al2O3). The catalytic phase was synthesized by the Citrate method. The LPG combustion was studied and the process parameters were analyzed (flame speed, total efficiency, equivalence ratio, emissions), the parameters were evaluated in an inert and catalytic medium. By coating the Al2O3 porous medium with perovskite catalysts, a reduction in CO (58%) and NO (87%) emissions was observed in the reduction of the equivalence ratio (ɸ) 0,7. The burner had a maximum total efficiency of 94,31% in the catalytic bed. Temperatures are achieved with higher efficiencies and lower emissions of pollutants in the combustion process with the use of perovskites. |
