Potential Application of Turnip Oil (Raphanus sativus L.) for BioDiesel Production: Physical–Chemical Properties of Neat Oil, Biofuels and their Blends with Ultra-Low Sulphur Diesel (ULSD)
BioEnergy Research, 2013Co-Authors: Shailesh N Shah, Flavio C S C Alves, Brajendra K Sharma, Sevim Z Erhan, Osvaldo K. Iha, Paulo A Z SuarezAbstract:Turnip oil (TO; Raphanus sativus L.) produces seeds that contain around 26 wt% of inedible base stock that are suitable as a potential feedstock for bioDiesel production. A turnip oil methyl ester (TME) was prepared from acid-catalyzed pretreated TO in an effort to evaluate important fuel properties of turnip oil-based bioDiesel, such as kinematic viscosity, cloud point, pour point (PP), cold filter plugging point, acid value, oxidative stability and lubricity. A comparison was made with soybean oil methyl esters (SME) as per bioDiesel fuel standards such as ASTM D6751 and EN 14214. TME was characterized using FTIR, HPLC and ^1H NMR. Except PP property, SME displays superior fuel properties compared to TME. Blends (B5 and B20) of TME in ultra-low sulphur Diesel fuel (ULSD) were also assessed for the aforesaid fuel properties and compared to an analogous set of blends of soybean oil methyl ester in ULSD as per petro Diesel fuel standards such as ASTM D975 and D7467. TME B5 blends in ULSD displayed improved PP property in comparison to neat ULSD and blends of SME in ULSD. It was demonstrated that the B5 and B20 blends of TME in ULSD had acceptable fuel properties as per ASTM D975 (for B5 blend) and ASTM D7467 (for B20 blend). In summary, turnip oil has potential as an alternative, non-food feedstock for bioDiesel production.

Physico-Chemical Characteristics of Particulate Emissions from Diesel Engines Fuelled with Waste Cooking Oil Derived BioDiesel and Ultra Low Sulphur Diesel
Biodiesel - Feedstocks Production and Applications, 2012Co-Authors: Raghu Betha, Rajasekhar Balasubramanian, Guenter EnglingAbstract:A ground breaking invention in 1893 by Rudolf Diesel (Diesel Engine – named after him) made a mark in the world of internal combustion engines; his engine was the first one to prove that fuel could be ignited without a spark. Since this invention, Diesel engines have been widely used in various applications such as automobiles, agriculture, ships, electricity generators, construction equipment etc., all over the world. Diesel engines were proved to be very efficient in terms of delivering the required energy levels for their use at very low operating and maintenance costs when compared to gasoline engines. However, Diesel en‐ gines now pose a serious threat to human health and adversely impact the urban air quality (Sydbom et al., 2001). Diesel engine exhaust contains a host of harmful substances including airborne particulate matter (PM), carbon soot, toxic metals, polycyclic aromatic hydrocar‐ bons (PAHs), nitrogen oxides which induce ozone formation, carbon monoxide, carbon di‐ oxide, volatile organic compounds and other compounds such as formaldehyde and acrolein (EPA, 2002). Of these pollutants, PM from Diesel exhaust is of great concern because of a number of reasons: (1) Diesel engines are known to be the largest source of PM from motor vehicles. Two thirds of PM emitted from mobile sources are from Diesel vehicles (EPA, 2002); (2) Human exposure to Diesel exhaust particles (DEP) is high as these particles are emitted at ground level unlike that of smoke stacks. United Stated of Environmental Pro‐ tection Agency (USEPA) reported that 83% of people living in the USA are exposed to con‐ centrated Diesel emissions from sources such as highways, heavy industries, construction

Comparative in vitro cytotoxicity assessment of airborne particulate matter emitted from stationary engine fuelled with Diesel and waste cooking oil-derived bioDiesel
Atmospheric Environment, 2012Co-Authors: Raghu Betha, Shruti Pavagadhi, Swaminathan Sethu, M. Prakash Hande, Rajasekhar BalasubramanianAbstract:BioDiesel derived from waste cooking oil (WCO) is gaining increased attention as an alternative fuel due to lower particulate emissions and other beneficial factors such as low cost and utilization of waste oil. However, very little information is available on toxicity of airborne particulate matter (PM) emitted from bioDiesel combustion. In this study, PM emitted from WCO-derived bioDiesel (B100) was analyzed for its toxic potential together with ultra low sulphur Diesel (ULSD) as a reference fuel and their blend (B50). Human lung epithelial carcinoma cells (A549) were used for this comparative toxicity study. Results indicate that cytotoxicity and oxidative stress were higher for B100 relative to ULSD. Furthermore, caspase 3/7 activity indicates that cell death induced by B100 was due to either caspase independent apoptotic process or other programmed cell death pathways. The toxicity was also evaluated for different engine load conditions. It was observed that at lower loads there was no significant difference in the toxicological response of B100 and ULSD. However, with increase in the engine load, B100 and B50 showed significantly higher toxicity and oxidative stress compared to ULSD.

emissions of particulate bound elements from stationary Diesel engine characterization and risk assessment
Atmospheric Environment, 2011Co-Authors: Raghu Betha, Rajasekhar BalasubramanianAbstract:There has been an increasing concern about the emissions of airborne particulate matter (PM) from Diesel engines because of their close association with adverse health and environmental impacts. Among the alternative fuels being considered, bioDiesel made by the transesterification of waste cooking oil has received wide attention in recent years because of its low cost and the added advantage of reducing waste oil disposal. This study was conducted to make a comparative evaluation of the particulate-bound elements emitted from ultra low sulphur Diesel (ULSD) and waste cooking oil-derived bioDiesel (B100) and a blend of both the fuels (B50). It was observed that the PM mass concentrations were reduced by about 36% when B100 was used. Crustal elements such as Mg, K and Al were found to be in higher concentrations compared to other elements emitted from both B100 and ULSD. Zn, Cr, Cu, Fe, Ni, Mg, Ba, K were found to be higher in the bioDiesel exhaust while Co, Pb, Mn, Cd, Sr, and As were found to be higher in the ULSD exhaust. To evaluate the potential health risk due to inhalation of PM emitted from Diesel engines running on ULSD and B100, health risk estimates based on exposure and dose–response assessments of particulate-bound elements were calculated assuming exposure for 24 h. The findings indicate that the exposure to PM of the B100 exhaust is relatively more hazardous and may pose adverse health effects compared to ULSD.
