摘要

Polychlorinated dibenzo-p-dioxin/dibenzofuran (PCDD/F) emissions from heavy-duty diesel engines (HDDEs) fuelled with paraffinic-palmbiodiesel blends have been rarely addressed in the literature. A high-resolution gas chromatograph/high-resolution mass spectrometer (HRGC/HRMS) was used to analyze 17 PCDD/F species. Experimental results indicate that the main species of PCDD/Fs were OCDD (octachlorinated debenzo-p-dioxin) and OCDF (octachlorodibenzofuran), and they accounted for 40-50% of the total PCDD/Fs for all test fuels. Paraffinic-palmbiodiesel blends decreased PCDD/Fs by 86.1-88.9%, toxic PCDD/Fs by 91.9-93.0%, THC (total hydrocarbons) by 13.6-23.3%, CO (carbon monoxide) by 27.2-28.3%, and PM (particulate matter) by 21.3-34.2%. Using biodiesel blends, particularly BP9505 or BP8020, instead of premium diesel fuel (PDF) significantly reduced emissions of both PCDD/Fs and traditional pollutants. Using BP9505 (95vol% paraffinic fuel+5vol% palmbiodiesel) and BP8020 instead of PDF can decrease PCDD/F emissions by 5.93 and 5.99gI-TEQyear-1 in Taiwan, respectively.
