Özet

One of the main causes of environmental pollution is the exhaust emissions emitted from internal combustion engines. Currently, the use of rare elements such as platinum, palladium and rhodium in metal catalysts, which form part of exhaust purification systems, causes production difficulties and increased costs. Furthermore, these elements do not possess particle retention properties. This study aimed to determine whether geopolymer materials could be used as an innovative exhaust purification system in the automotive industry, given that porous geopolymer structures contain catalyst materials, are resistant to pressure and temperature, are easy and inexpensive to apply, and can be made from waste raw materials. In this study, newly developed aluminum-carbon-boron (5% Al2O3 and 1% activated carbon) doped emission treatment filter (also named as “AlCBDoF”) and zirconium-boron (5% ZrO2 and 5% Zr(SO4)2) doped emission treatment filter (also named as “ZrBDoF”) are developed and their effects on the diesel engine performance and emissions were investigated. The developed novel emission treatment filters and a standard catalytic converter of the diesel engine were separately installed in the exhaust after treatment line of a 4-cylinder diesel engine under different speeds and loads. When standard catalytic converter is used, HC emissions are improved by up to 48%, while HC emissions are reduced by 60% when AlCBDoF is used and 70% when ZrBDoF is utilized. The fact that the filter output values of the CO2 are higher than the filter input values shows that the filters are effective in CO2 conversion of CO emissions by acting as a catalyst. It has also been observed to demonstrate over 99% improvement in particulate matter. Therefore, the newly developed Boron Doped Filters can be used as a single device instead of both Diesel Oxidation Catalyst and Diesel Particulate Filter. In addition to improving exhaust emissions, it has been shown that the developed products are environmentally friendly system with the ability to utilize waste products and they can be used as innovative materials in exhaust emission control in the automotive industry.
