Abstract

The agricultural wastes in the form of rice husk ash, manufacturing solid wastes consisting of pulp grits, dregs, and biosludge as well as motor vehicle exhaust gases containing carbon monoxide, hydrocarbons and carbon dioxide are pollutants that endanger humans and other living things. In fact, the mineral content in pulp solid waste and rice husk ash can be converted into catalytic converters that absorb and convert pollutants from vehicle flue gases so that the amount released into the air is decreased. Therefore, the use of catalytic converters in motor vehicle exhaust is one of the solutions to reduce the air pollution. The ratio of zeolite weight from rice husk ash to pulp solid waste and the number of holes in the catalytic converter are important factors that can affect the performance and mechanical properties of the catalytic converter. The catalytic converter with a zeolite weight ratio of rice husk ash to pulp solid waste at 4:5 and a number of holes at 8 has an absorption power of carbon monoxide (CO), hydrocarbon (HC) and carbon dioxide (CO2) gases of about 54.83; 71.19 and 36.95%, respectively, with a conversion power indicated by an increasing oxygen content in the flue gas by 23.81%.
