Numerical simulation of the effect of material catalytic converter on gas emission

The disposal of gas emission from vehicle is the biggest contributor to the environmental pollution which generates most carbon monoxide, hydrocarbon, and lead (Pb=Plumbum). Those substance particulates are pollutants and harmful for both the environment and human life. One of the innovations that can reduce the pollutive particulates is to reduce CO gas by assembling a catalytic converter are displayed. In order to find out the effect of catalytic converter absorption toward (CO) gas particulate, varied with various materials in an environmentally friendly catalytic converter, a simulation using fluent software is carried out. From the simulation, it is seen a significant thermal condition and CO mass fraction absorption from various different materials, by applying mass fraction of CO=0.04;N₂=0.8796; and O₂=0.12, the decrease of high mass fraction (decrease of CO=0.004 mass fraction) occurs at the channel centre area due to the mass fraction of various materials that moves away from the center with a longer rest time (high conversion) at the surrounding channel.
