“…Figure 4 shows the lineal correlation between HCV and ternary-component percentages of the blend. According to previous studies [39], this property does not show any synergic or antagonistic interaction with mixture components, so an efficient adjustment may be achieved by a first-order model.…”

“…This function is called desirability function d i (Y i ) and takes values between 0 and 1 (Costa et al, 2011). When d i (Y i ) takes values close to 1, it means that the response is the ''most desirable'' (Pinzi et al, 2011a).…”

“…The use of LCV as available energy in fuel combustion is due to exhaust gases temperature in the combustion, which is much further above room temperature, so the condensation of water vapor must be considered (Pinzi et al, 2011a). In this way, LCV for DOE II, DOE III and conventional transesterification are 36,907, 37,024 and 37,373 J/g respectively.…”

“…The percentages of FAMEs with 18 carbons in the biodiesel from the three types of sludge were 37.0% (RAS), 56.4% (CAS) and 66.8% (CGS), whereas the proportions of 16-carbon FAMEs were 47.6% (RAS), 19.6% (CAS) and 18.8% (CGS), respectively (Figure 3). The heating value would rise with the increase of the chain length (Pinzi et al, 2011); thus, the biodiesel produced from aerobic granular sludge may have a higher heating value. Apart from the increase of fatty acids with 18 carbons, more branched FAMEs were also found in the CAS and the CGS fed with synthetic sugarcontaining wastewater.…”

a b s t r ac tUtilizing excess sludge from wastewater treatment plant to produce biodiesel is becoming increasingly popular, but it has been limited by the low lipid content in activated sludge. This study was designed to enhance biodiesel production from granular sludge fed with synthetic sugar-containing wastewater. The experiments were conducted in two 1.2-L sequencing batch reactors under different sludge settling times to cultivate granular sludge and activated sludge. The biodiesel yield of the granular sludge (30.14 ± 0.73 mg/g suspended solids [SS]) was higher than that of the activated sludge (21.56 ± 0.95 mg/g SS) with the same feedings. The distributions of fatty acid methyl esters varied among the seed sludge, the cultured sludge flocs and the granular sludge. Methyl 14-methylpentadecanoate (14MeC15:0), methyl oleate (C18:1) and methyl linoleate (C18:2) were the three components of the biodiesel produced from the granular sludge that increased the fastest, which might promote the heating value and the low temperature fluidity of biodiesel. The remarkable change of microbial community and the dominance of filamentous fungi Phialophora after sludge granulation might contribute to the intrinsic change in the fatty acids, which resulted in a higher yield and a better quality of biodiesel.
