“…Analytical results reveal that using WCOB instead of ULSD can reduce emissions of SO x and PAHs. Previous studies indicate that the viscosity, flash points and pour points of biodiesel is higher than that of diesel Legreid et al, 2007;Lin et al, 2009). High viscosity is good for the lubrication of engines, but it causes poor nebulization, resulting in poor combustion.…”

The development of biodiesels is being driven by the need for reducing emissions from diesel engines without modifying engines and for saving energy. The major obstacle to biodiesel commercialization is the high cost of raw materials. Biodiesel from waste cooking oil is an economical source and an effective strategy for reducing the raw material cost. Although biodiesels made from waste cooking oil have been previously investigated, PAH emissions from heavy-duty diesel engines (HDDEs) with catalyzer fueled with biodiesel from waste cooking oil and its blend with ultra-low sulfur diesel (ULSD) for the US-HDD transient cycle have seldom been addressed. Experimental results indicate that ULSD/WCOB (biodiesel made from waste cooking oil) blends had lower PM, HC, and CO emissions but higher CO 2 and NO x emissions when compared with that of ULSD. Using ULSD/WCOB blends instead of ULSD decreased PAHs by 14.1%-53.3%, PM by 6.80%-15.1%, HC by 6.76%-23.5%, and CO by 0.962%-8.65% but increase CO 2 by 0.318-1.43% and NO x by 0.384-1.15%. Using WCOB is an economical source and an effective strategy for reducing cost, and solves the problem of waste oil disposal.

“…FC1: high loadings of formaldehyde, benzaldehyde and tolualdehyde are related to gasoline engines emissions, whereas acetone, propionaldehyde and hexaldehyde are related to petrochemical industry emissions. FC2: high loadings of acetaldehyde and isovaleraldehyde are related to food industry emissions , whereas acetaldehyde, crotonaldehyde and cyclohexanone are found in diesel engines emissions (Schauer et al, 1999;Peng et al, 2008;Lin et al, 2009). FC3: high loadings of heptaldehyde, octaldehyde, nonaldehyde and decylaldehyde are related to restaurant emissions.…”

The concentrations of 18 atmospheric carbonyls species were measured at Nan-Chie and Hsiung-Kong sites in Kaohsiung City, Taiwan, during the summer and winter of 2006. Formaldehyde and acetaldehyde were the most abundant carbonyls with respective annual mean concentrations of 17.99 μg/m 3 and 13.69 μg/m 3 at Nan-Chie, and 21.47 μg/m 3 and 16.68 μg/m 3 at Hsiung-Kong; altogether the two species accounted for approximately 56-57% of total carbonyls. In summer, the total concentrations of carbonyls were 74.06 μg/m 3 and 89.99 μg/m 3 at Nan-Chie and Hsiung-Kong, respectively. In winter, the concentrations were 37.14 μg/m 3 and 46.50 μg/m 3 at Nan-Chie and Hsiung-Kong, respectively. Measured results indicated the predominance of photolysis and photooxidation reactions of aldehydes in summer. In this study, receptor models using principal component analysis (PCA) and absolute principal component scores (APCS) suggest that the primary pollution sources at Nan-Chie in the summer were secondary emissions/vehicle exhausts (gasoline engines)/stationary emissions (food industry), stationary emissions (petrochemical)/waste treatment and restaurant emissions; the primary pollution sources at Nan-Chie in winter were vehicle exhausts (gasoline engines)/stationary emissions (petrochemical) and restaurant emissions. At Hsiung-Kong, the primary pollution sources in summer were secondary emissions/vehicle exhausts (gasoline engines and diesel engines)/stationary emissions (metal assembly), restaurant emissions and others; the primary pollution sources in winter were vehicle exhausts (gasoline engines)/restaurant emissions and vehicle exhausts (diesel engines)/stationary emissions (metal assembly).

Abstract. Solid-liquid equilibria for binary mixtures of {Methyl palmitate (1) + Naphthalene (2)} were measured using differential scanning calorimeter (DSC). Simple eutectic behaviours for this system are observed. The experimental results were correlated by means of the NRTL, Wilson, UNIQUAC and ideal models. The root-mean-square deviations of the solubility temperatures for all measured data vary from 0.5477 K (for UNIQUAC model) to 3.34K; the deviation depend on the model used. The best solubility correlation was obtained with UNIQUAC model and this observation confirms previous results.
