Abstract

Catalytic Converter adalah teknologi yang digunakan untuk mengurangi polusi udara yang dipasang pada saluran gas buang (knalpot) kendaraan motor bensin. Catalytic Converter ini berfungsi untuk mempercepat oksidasi emisi gas Hidrokarbon (HC) dan Carbon Monoksida (CO), serta mereduksi Nitrogen Oksida (NOx).Perubahan emisi gas buang tersebut di atas sangat dipengaruhi oleh temperature kerja pada Catalytic Converter. Material logam Tembaga Krom sebagai bahan katalis, akan diteliti ini diuji dalam skala laboratorium, yang pertama untuk melihat pengaruh perubahan putaran mesin terhadap temperature, kedua perubahan temperature saat mengunakan Catalytic Converter dengan katalis Tembaga dan ketiga perubahan temperature saat menggunakan Katalis Temnbaga Krom pada saluran gas buang. Hasilpenelitian diperoleh pertama bahwa perubahan putaran mesin  mempengaruhi kenaikan temperatur Catalytic Converter, semakin tinggi putaran mesin temperature naik dan sebaliknya pada putaran mesinrendah terperature cenderung turun. Kedua pemasangan Catalytic Converter menyebabkan temperature menjadi turun, pada putaran mesin 3000 rpm (tampa Catalytic Converter) temperature 317,5 ºC dan turunmenjadi 227,36 ºC pada 5 sel katalis, 218 ºC pada 10 sel dan 230 ºC pada 15 sel. (dengan Catalytic Converter Cu). Sedangkan pada pemasangan Catalytic Converter katalis Tembaga Krom , pada putaran mesin 3000rpm (tampa Catalytic Converter) temperature 317,5 ºC turun menjadi 237,5 ºC pada 5 sel katalis, 240,84 ºC pada 10 sel dan 249 ºC pada 15 sel, dimana penurunan temperature yang terjadi, lebih tinggi denganpemakaian katalis Tembaga.Kata Kunci : Putaran Mesin, Temperature, Catalytic Converter, Tembaga Krom

Abstract

Catalytic Converter  adalah teknologi yang digunakan untuk mengurangi polusi udara yang dipasangpada saluran gas buang (knalpot) kendaraan motor bensin. Catalytic Converter ini berfungsi untukmempercepat oksidasi emisi gas Hidrokarbon (HC) dan Carbon Monoksida (CO), serta mereduksiNitrogen Oksida (NOx). Perubahan emisi gas buang tersebut di atas sangat dipengaruhi olehtemperatur kerja pada Catalytic Converter. Pada penelitian ini dilakukan dalam skala laboratorium dengan mengkaji material logam transisiMangan sebagai supporting katalis Tembaga, untuk melihat pengaruh perubahan putaran mesinterhadap  temperature dan perubahan temperature kerja Catalytic Converter. Dimana tujuan pertamauntuk mengkaji pengaruh perubahan putaran mesin terhadap temperatur Catalytic Converter bahankatalis Tembaga Mangan. Sedangkan yang kedua adalah mengkaji pengaruh pemasangan CatalyticConverter terhadap temperature kerja Catalytic Converter. Hasil penelitian diperoleh pertama bahwa perubahan putaran mesin mempengaruhi kenaikantemperatur Catalytic Converter, semakin tinggi putaran mesin temperatur naik dan sebaliknya padaputaran mesin rendah suhu cenderung turun. Kedua pemasangan Catalytic Converter menyebabkantemperature  menjadi naik, pada putaran mesin 3000 rpm (tampa Catalytic Converter) temperature240 ºC dan meningkat menjadi 250 ºC (Catalytic Converter katalis Tembaga). Sedangkan padapemasangan Catalytic Converter katalis Tembaga Mangan terperatur kerja lebih baik, menjadi naiklebih tinggi lagi yaitu mencapai 300 ºC. Hal ini membuktikan bahwa pemasangan Catalytic Convertermeningkatkan kemampuan kinerja katalis dengan semakin meningkatnya temperature.

Abstract

This study characterizes copper (Cu) and chrome-plated copper (Cu-Cr) catalyst materials used in catalytic converters for gasoline engines. The objective is to investigate morphological and compositional changes resulting from exhaust gas emission testing. Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray Spectroscopy (EDX) was employed for microstructural analysis of the catalyst materials. The research examines morphological changes in Cu and Cu-Cr catalysts before and after exhaust gas emission testing, along with elemental composition alterations. Results indicate that exhaust gas exposure significantly alters the morphology and composition of both catalyst types. Morphologically, Cu catalyst particles originally flat with fine grains exhibited rougher, uneven surfaces with random grain formations and porosity post-testing. Similarly, Cu-Cr catalyst surfaces transformed from smooth to uneven, marked by darkened spots. Compositionally, Cu catalysts initially consisting of five elements (Cu 82.92%, O 5.96%, C 10.22%, Cl 0.60%, Si 0.29%) changed to include eight elements (Cu 70.65%, O 12.89%, C 12.85%, Cl 0.66%, Si 0.27%, N 1.74%, Al 0.27%, S 0.67%). Cu-Cr catalysts initially composed of three elements (Ni 87.65%, Cr 10.50%, C 1.85%) evolved to five elements (Ni 86.01%, Cr 6.56%, O 5.70%, O 1.42%, S 0.71%). These findings underscore the transformative effects of exhaust gas exposure on catalyst materials, influencing both their morphology and elemental composition, crucial for enhancing catalytic converter performance and durability in automotive applications.

Abstract

The technology used to reduce air pollution is using a Catalytic Converter which is installed on the exhaust gas channel (muffler) of gasoline motorized vehicles. This Catalytic Converter serves to accelerate the oxidation of Hydrocarbon (HC) and Carbon Monoxide (CO) emissions, as well as to reduce Nitrogen Oxide (NOx). In this study it was designed in such a way on a laboratory scale by studying the manganese transition metal material as a supporting copper catalyst, to see the ability of the catalyst to reduce carbon monoxide exhaust emissions. This study aims first to examine the ability of the manganese transition metal catalyst as a support for copper (CuMn) and secondly to examine the effect of increasing the number of catalyst cells on exhaust emission output. The first research results obtained were that the Manganese Transition metal catalyst as a supporting Copper (CuMn) was able to reduce the output of Carbon Monoxide exhaust emissions. Second, the addition of the number of catalyst cells on the Copper (Cu) catalyst did not have a significant effect, while the addition of the number of catalyst cells on the Manganese Transition metal catalyst as a support for Copper, from 5 catalysts to 10 catalysts, was able to reduce the output of Carbon Monoxide exhaust gas more significantly. However, in the number of 15 catalyst cells, the reduction in exhaust emissions was not significant.
