The aim of this study was to increase the oxidation stability of biodiesel from sunfl ower-oil by partial-hydrogenation. Activated carbon, which was obtained from viscum album L., was used as a new and effective original phase transfer catalyst during partial hydrogenation. Temperature, pressure, and catalyst/biodiesel ratios were selected as the experimental parameters and their effects on the oxidation stability were investigated by using the 2 3 factorial design. A fi rst-order model was obtained using analysis of variance. The physical properties such as density, viscosity, pour point, and cloud point of sunfl ower biodiesel samples were determined using the standard methods. The oxidative stability (induction period, IP) values were found experimentally by the Rancimat method and cis and trans-confi gurations of the biodiesel samples were characterized by Fourier transform infrared (FTIR) spectra before and after hydrogenation. Partially hydrogenated biodiesels were found to have better oxidative stability, and lower pour point and cloud point properties compared to non-hydrogenated sunfl ower biodiesel. It can be stated that kinematic viscosities and the densities of the partial hydrogenated biodiesels did not change signifi cantly.

Currently, biodiesel produced from algae is receiving a positive response as a substitute for conventional base diesel. To cope up from the costs of expensive downstream stages in the production of biodiesel from algae, present investigation is conducted using algae growing in wastewater as lipid source for biodiesel production. The in situ transesterification using algae was carried to optimize the effect of reaction parameters on the biodiesel yield. The parameters studied were: temperature (35-75 ºC), algae biomass (wt.) to methanol (vol.) ratio (1:1-1:6), catalyst concentration (25-100 wt. %) and stirring intensity (150-750 rpm). The optimum conditions for maximum biodiesel yield achieved were: catalyst concentration and algae biomass to methanol ratio were 60 % and 1:4, respectively with stirring intensity of 450 rpm at 55 ºC. The gas chromatographic studies and fuel properties of biodiesel also establish its potential to be used as fuel in existing engines in accordance to American and European standards.

“…2 Owing to the many possible feedstocks, the FAME composition of biodiesels may therefore vary substantially in terms of the carbon length, substitution, and degree of unsaturation. [11][12][13][14][15][16][17] There are other studies using biodiesel blends with the same goals. [3][4][5][6][7][8] Waste greases, such as used cooking oil and animal fats, are attractive biodiesel feedstocks mainly due to their low cost and environmental benets.…”

Using the L/O ratio to determine blend composition in biodiesel by EASI-MS corroborated by GC-FID and GC-MS

Easy ambient sonic-spray ionization mass spectrometry (EASI-MS) is applied to the analysis of biodiesel blends prepared from soybean and animal fat biodiesel. A correlation was established between the ratio of abundance of linoleic acid (L) and oleic acid (O) methyl ester ions with the biodiesel blend composition. To compare these results from the EASI-MS technique, the L/O ratio of these blends was also determined using both gas chromatography with flame ionization detection (GC-FID) and gas chromatography with mass spectrometry (GC-MS). Both these classical techniques confirmed that the ratio between the mass fraction of FAME from L and O as measured by EASI-MS is indeed correlated with the blend composition of soybean-animal fat biodiesel.
