Pemanfaatan Karbon Aktif dari Limbah Kulit Pisang untuk Catalytic Converter pada Mesin Diesel

Abstract

The phenomenon of environmental pollution in the machinery system is problem that often occurs. One of them is the emission from burning fossil fuels of diesel engines. Therefore, it is necessary to do proper handling to reduce the emission content of diesel engines, one of which is by using catalytic converter engineering technology. In this study, the catalytic converter was made using an activated carbon filter from banana peel waste with sodium hydroxide (NaOH) activator. The activated carbon formed is then mixed with nickel oxide powder to be used as catalyst and white cement as binder. Diesel engine emission testing is carried out with time variations from 3 to 12 minutes. The results show that there is decrease in the content of carbon monoxide (CO) obtained by 57% when testing emissions at minute 12. While for the content of NOx and NO there is decrease of 43%. This indicates that the mixture of activated carbon from banana peel waste and nickel oxide powder is very effective in reducing the content of diesel engine exhaust emissions.

“…Struktur pori seperti itu menyebabkan karbon aktif memiliki kemampuan adsorpsi yang tinggi sehingga banyak diaplikasikan dalam berbagai aplikasi praktis. Aplikasinya sangat luas meliputi penyimpanan gas metana [2][3][4], pemurnian biogas [5,6], menghilangkan zat pewarna [7], penyerapan CO 2 [2,[8][9][10], penghilangan polutan knalpot dari mesin diesel [11], sebagai bahan filter pada catalytic converter [12], sebagai bahan super kapasitor [13], dan masih banyak aplikasi lainnya.…”
