Abstract
The use of catalytic converters from pulp waste and rice husk ash is one way to reduce pollutants in exhaust gases. This study examines the effect of the design 6, 7, 8 and 9 of hole positions on the catalytic converter toward its performance and mechanical properties. Rice husk ash was converted into zeolite through a hydrothermal reaction. Zeolite X from rice husk ash and pulp waste with a weight ratio of 4:5 was used as a material for making a catalytic converter through a granulation, mixing, molding and combustion process. The results of gas analyzer measurements showed that the 7-hole catalytic converter with a hole position design spread across the surface had the most effective performance in absorbing CO, HC and CO2 gas pollutants of 67.10- 66.24 and 67.80%, respectively. This catalytic converter has mechanical properties of resistance to pressure and temperature of 0.005 MPa and 89 ⁰-C, respectively
