“…Among the several recipes for bio-diesel production, transesterification as a simple chemical reaction between stirred alcohol, and vegetable oils in the presence of heat and catalyst could not produce low viscosity and ash content bio-diesel especially by using high viscosity vegetable oils such as raw Castor oil. The Oxygen content of biodiesel, which increased the specific fuel consumption, synthesized by transesterification is due to the Oxygen content of the alcohol in the chemical reaction as stated by Abu-Elyazeed et al and Slim et al [10,11]. In contrary of transesterification, pyrolysis process could produce not only low viscosity, ash content, and nil Oxygen bio-diesel but also bio-mazot as a low grade fuel oil.…”

The jojoba plant (Simmondsia chinensis L.) produces seeds that contain around 50 to 60 wt.% of inedible long-chain wax esters that are suitable as a potential feedstock for biodiesel (BD) production. Jojoba oil methyl esters (JME) were prepared from acid-catalyzed pretreated jojoba oil in order to evaluate important fuel properties of jojoba-based BD, including kinematic viscosity, cloud point (CP), pour point (PP), cold filter plugging point (CFPP), acid value (AV), oxidative stability, and lubricity. A comparison was made with soybean oil methyl esters (SME) and relevant BD fuel standards such as ASTM D6751 and EN 14214. JME was characterized using Fourier transform infrared spectroscopy and 1 H and 13 C nuclear magnetic resonance. The CP, PP, and CFPP of JME were −13°C, −16°C, and −14°C, respectively, which were superior to SME. The kinematic viscosity (40°C) of JME was 6.67 mm 2 /s, which was higher than observed for SME. Blends (B5 and B20) of JME in ultra-low sulfur diesel fuel (ULSD) were also evaluated for the aforementioned fuel properties and compared to an analogous set of blends of SME in ULSD and relevant petro diesel fuel standards such as ASTM D975 and D7467. JME blends in ULSD displayed improved low-temperature properties in comparison to neat ULSD and blends of SME in ULSD. In summary, jojoba oil has potential as an alternative, nonfood feedstock for BD production.

Improvement of the oxidative stability of soybean oil (SBO) by blending with jojoba oil (JO) was investigated. SBO in the presence of 5, 10, 15 and 20 wt-% of JO was subjected to accelerated storage at 60 7C. Peroxide values (PV), anisidine values (AV), UV absorption characteristics (K 232 and K 270 values), and headspace volatiles were determined to monitor the oxidative stability of oil samples. JO was effective in reducing the formation of hydroperoxides and volatile compounds in SBO. The effect was remarkable in SBO/JO blends containing 15 and 20% JO, which showed significant reductions in PV, AV and volatile content with respect to pure SBO. The increased oxidative stability of SBO/JO blends could not be attributed to JO tocopherols, since the addition of JO to SBO significantly reduced the tocopherol content of SBO. Besides the tocopherol content and unsaturation degree of SBO and JO, the effect of the JO ester structure on the oxidative stability of the blends is discussed. The enhanced chemical and flavor stabilities of SBO/JO blends with respect to pure SBO may make a significant contribution to improve the shelf life of SBO by reducing the deterioration reactions related to lipid peroxidation.
