ANALISIS VARIASI TEMPERATUR LOGAM KATALIS TEMBAGA (Cu) PADA CATALYTIC CONVERTER UNTUK MEREDUKSI EMISI GAS KARBONMONOKSIDA (CO) DAN HIDROKARBON (HC) KENDARAAN BERMOTOR
Abstract: The air pollution rate
caused by the vehicles in big cities is now reach the critical limit. It
affects the environmental health as well as the financial factors. To reduce
the pollutant gas from the vehicle engines emission, a technology is needed.
One of the technology is the application of catalytic converter inside the exhaust emission. A research has
been done on 125 cc motorcycle engine to modify its exhaust emission. The
catalysts used in this research was made of copper and designed using the
honeycomb system with various diameters ( 4, 6, 8, 10, 12 mm). The observation
variables are catalyst temperature, COand HC emissionrate. The emission of CO
and HC from the sample engine was then compared with the standard emission
rates. Result showed that increase of the copper catalyst temperature resulted
in decrease of CO and HC emission rates.
The decrease started to occur for all the catalysts at 225 oC. Optimum
convertion efficiency is up to 47,93 % (CO) and 50,36 % (HC). Both optimum
efficiency reached at the temperature of 325 oC using 8 mm diametered
catalysts.
