ELEMENTAL ANALYSES FOR DIFFERENT TYPES OF BIODIESEL AND DIESEL

Autor/autori: Dragos TUTUNEA, Marin BICA

Rezumat: Introducerea biodieselului pe piata ca o alternativa viabila la combustibilul diesel fosil pentru aplicatii in motoarele cu aprindere prin compresie (CI) a dus la o cercetare intensiva in acest domeniu in ultimile doua decenii. Acest lucru se datoreaza epuizarii resurselor de petrol si a cresterii gradului de constientizare al impactului asupra mediului si a sanatatii din arderea dieselului fosil. Pe masura ce utilizarea biodieselului devine mai raspandita, producatorii de motoare motoare si-au exprimat ingrijorarea cu privire la performantele acestuia in motoarele diesel. In aceasta lucrare este deteminata compozitia elementara pentru diferite tipuri de biodiesel din uleiuri (grasimi animale) si motorina. Datele experimentale obtinute indica continutul de carbon, hidrogen si azot prezent in fiecare proba. Procesul de combustie in motoarele diesel este analizat in functie de compozitia elementara a fiecarui combustibil.

Abstract: The biodiesel introduction on the market as economically viable alternative to fossil diesel for applications in compression ignition (CI) engines has led to intense research in the field over the last two decades. This is predominantly due to the depletion of petroleum resources and increasing awareness of environmental and health impacts from the combustion of fossil diesel. As the use of biodiesel becomes more widespread, engine manufacturers have expressed concern about his performance in diesel engines. In this paper is determined the elemental composition for different type of biodiesel from oils (animal fat) and petrodiesel. The experimental data obtained indicate the content of carbon, hydrogen and nitrogen present on each probe. The combustion process in diesel engines is analyzed function of elemental composition of each fuel.

Keywords: elemental composition, combustion, biodiesel, petrodiesel
