ATIK POLİETİLEN PİROLİZİNİN DİZEL MOTOR ve EMİSYON PARAMETRELERİNE ETKİSİNİN İNCELENMESİ

Öz

Plastik malzemelerin kullanılmasının artışıyla birlikte Polietilen (PE) nin de kullanımı da bütün dünyada artmıştır. Bu yüksek miktardaki PE doğal bozulmama özelliğinden dolayı çevresel problemleri de beraberinde getirmektedir. Fakat bu PE sıvı yakıtlara dönüştürülebildiği için çevresel ve ekonomik olarak fayda sağlayabilir. Bu deneysel çalışmada PE dizel yakıt katkısına dönüştürülerek polimer bazlı yakıtların dizel motorlarda eksoz emisyonu ve performans paramatereleri incelenmiştir. PE atıklar termal piroliz yöntemiyle yakıta dönüştürülmüştür. PE atık katkılı yakıt %5, %10 ve %20 oranlarında dizel yakıt ile karıştırılarak herhangi bir modifikasyon gerçekleştrilmeden test edilmiştir. Genel olarak motor performans ve eksoz emisyon değerleri dizel yakıtlar ile benzer özellikler göstermiştir. Spesifik yakıt tüketimi (SFC) değeri PE oranının artmasıyla hafif düzeyde artış göstermiştir. Karbonmonoksit (CO) ve azot oksit (NOx) değerleri de dizel yakıt ile karşılaştırıldığında artma eğilimi göstermiştir.

INVESTIGATION OF PYROLYSIS OF WASTE POLYETHYLENE (PE) AND EFFECTS ON DIESEL ENGINE AND EMISSION PARAMETERS

Öz

With the increment of usage of plastic materials, the use of polyethylene (PE) all over the world is also increasing. The great amount of PE usage results in a huge amount of PE waste. These huge amounts of PE wastes are generating environmental problems due to their non-degradable properties. But, PE wastes can be converted into liquid fuels for both economic and environmental benefits. In this experimental study, the conversion of PE wastes into diesel fuel and influence of the polymer-based fuels on the performance and exhaust emission of diesel engine was investigated. The conversion of PE wastes was carried out by utilizing the thermal pyrolysis process. The blends of the PE waste based fuel with diesel fuel were tested with three different ratios (5%, 10%, and 20%) in an unmodified direct injection diesel engine at full load condition. In general, engine performance and exhaust emission values of the blend fuels were similar to that of diesel fuel. Specific fuel consumption (SFC) values of the blend fuels slightly increased depending on the ratio of PE based fuel in the test fuels. The carbon monoxide (CO) and oxides of nitrogen (NO)x emissions of the blended fuels values showed an increasing trend as compared to the values of diesel fuel
