EXPERIMENTAL STADY OF USING OLIVE OIL AND BIODIESEL ON POLLUTANTS EMISSIONS IN THE CONTINUOUS COMBUSTION CHAMBER

Abstract

This study investigates the effect of using olive oil on the pollutants emissions in the continuous combustion chamber. The bio-fuels used are mixtures of olive oil with two types of hydrocarbon fuels (gas oil and kerosene). The pollutants measured include carbon monoxide CO, unburned hydrocarbon UHC, soot and nitrogen oxide NO_x .It is found that all pollutants have less percent emissions when using olive oil blended with percent addition of 5%, 10%, and 15%. The reduction in emission with olive oil blends is due to the existence of oxygen O₂ in the chemical structure of the olive oil which is sufficient to achieve the complete combustion. The test was conducted through the range of equivalence ratio between (0.85-1.7). Results showed that olive oil blends with gas oil brings about 45.63% reduction in UHC and 36.48% soot, while CO 32.24% and NOx showed only about 39.54% reduction from that of pure gas oil. Whilst, blends with kerosene, showed a reduction of about 48.92% in UHC and 42.13% soot, while for CO and NO_x the reduction was 37.41% and 42.85% respectively compared with those of pure kerosene emission.
