碩士 / 國立成功大學 / 環境工程學系碩博士班 / 96 / In order to change the color of FBFA appearance, enhance the viscosity of FBFA and reduce the feasibility of FBFA being used in the traveling diesel-vehicles (TDVs), the working items and method of study were as follows. 1. A discussion of manufacturing process and additives of FBFA and the establishment of two new ingredients of FBFA (RDS0.5 and PFO0.5); 2. Understanding the numbers, tonnage, horse power, tones per fishing boat and horse power per tone of fishing boat in Taiwan from 1992 to 2006; 3.Observing the color appearance of PDF, FBFA, RDS0.5 and PFO0.5; 4.The measurements of sulfur and total-aromatic contents, dynamic viscosity and T90 of PDF, FBFA, RDS and PFO; 5.The tests of mechanical performance and pollutant emissions for PDF, FBFA, RDS0.5 and PFO0.5, respectively on a diesel-engine dynamometer; 6.The test of FBFA, RDS0.5 and PFO0.5, respectively being used in three real-scale fishing boats; 7. The feasibility assessments of FBFA with new ingredients being used in road traveling diesel vehicles and real-scale fishing boats, respectively; 8. Proposing a leading direction of policy performance for new ingredient FBFA.
The major results and conclutions of this study are as follows：
(1). By using the appearance and color of fuel oil for the preliminary screening of illegal diesel fuel, the RDS0.5 will be a better choice for fishing-boat fuel.
(2). If the fishing boat fuel being used in the traveling diesel vehicles, the emission amount of SOx will be increased approximately by 162 times and the total-PAH emission will be also elevated very significantly. This is one of the major reasons why the fishing boat fuel being used illegally in the traveling diesel vehicle needs to be strongly prohibited. By using the mass balance analysis, by adding 0.5% RDS or 0.5% PFO in the fishing boat fuel (FBFA), the sulfur content of FBFA will be no significant change.
(3). The mean PM emission factors from the FBFA, RDS0.5 and PFO0.5 fueled diesel engines were higher than that of PDF by 72.2%, 63% and 87.4%, respectively and the mean total-PAH emission factors from the FBFA, RDS0.5 and PFO0.5 fueled diesel engines were higher than that of PDF by 72.2%, 63% and 87.4%, respectively. The fishing boat fuel being used in the traveling diesel vehicles did increase the emissions of both PM and PAHs.
(4). The results of real-boat testing displayed that by using RDS0.5 as fishing boat fuel can reduce the emission factors of PM by 43.5%, increase the emission factors of total-PAHs by 43.5% and showed no significant difference in total-BaPeq. It revealed that by using RDS0.5, the majority of advantage will be very positive.
(5). Performance of New policy: Replace the FBFA as RDS0.5. By looking the appearance and color of fuel oil, if a dark-brown color diesel-fuel is found during the preliminary screening process, the diesel fuel needs a further analysis for sulfur content.
