Performance of catalytic micro combustion using PtAl2O3 catalyst foam and lpg as fuel / Norashima Salleh
Kajian ini membincangkan prestasi pembakaran pemangkin menggunakan mikro Pt / Al2O3 busa pemangkin dan LPG sebagai bahan api dengan mendapatkan komposisi suhu gas serombong dan dinding pembakar menggunakan nisbah udara dan bahan api yang sama untuk semua sampel pemangkin. Pemangkin Platinum disokong ke busa pemangkin alumina telah dibangunkan melalui kaedah pengisitepuan dan kehadiran platinum pemangkin dikenalpasti menggunakan SEM dan EDX. Pemangkin yang dibangunkan mempunyai kadar Pt pemangkin 0.1% berat, 0.2% berat, 0.17% berat dan 0.07% berat. Proses pembakaran bermula pada suhu bilik ambien menghasilkan komposisi SO2 dan NOx yang rendah dan api dapat dikekalkan lebih daripada setengah jam. Dari data eksperimen, Sampel 2 menunjukkan kecekapan pembakaran tertinggi dengan 67,15% pada suhu 261.7oC. Berdasarkan analisis sampel diuji, mangkin yang lebih tinggi mampu memberi kecekapan pembakaran yang lebih tinggi, pelepasan haba yang tinggi dan pengeluaran gas berbahaya yang lebih rendah. _______________________________________________________________________________________________________ This study addresses the performance of catalytic micro combustion using Pt/Al2O3 catalyst foam using LPG as fuel by obtaining the composition of flue gas and the wall temperature of combustor using constant air to fuel ratio for all developed samples. Platinum catalyst supported onto alumina catalyst foam is developed through impregnation method and the presence of platinum catalyst is justified by characterizing the developed catalysts using SEM and EDX. The developed catalysts have Pt catalyst loading of 0.1 wt%, 0.2 wt%, 0.17 wt% and 0.07 wt%. Combustion process starts in ambient room temperature produces low composition of SO2 and NOx and the flame sustain over half an hour. From experimental data, Sample 2 shows the highest efficiency of combustion with 67.15% at temperature of 261.7oC. Based on the analysis of the samples tested, higher catalyst loading can provide higher combustion efficiency, high heat release and lower emission of harmful gaseous.
