“…Moreover, the BA oil quality parameters are quite similar to those of soy oil, which is one of the most used for biodiesel production. In addition, ethyl esters of BA oil showed cleaner combustion than petrodiesel [8]. This suggests that BA can be an attractive alternative for sustainable biodiesel production.…”

a b s t r a c tContributing to extending the knowledge for the design and operation of biodiesel production processes, isobaric PTxy vapor-liquid equilibria data of ethanol + ethyl hexanoate, 1-pentanol + ethyl hexanoate and 1-pentanol + ethyl octanoate at two different pressures are reported for the first time. Consistency tests were applied to attest the quality of the collected data, for these especially complex measurements. Besides that, vapor pressures of the pure ethyl esters have also been measured. For modeling purposes, the Lyngby and Dortmund UNIFAC variants were used to predict the VLE phase diagrams. Generally, the predictions are of very good quality, being the UNIFAC-Do (Dortmund) better, as the deviations in temperature and vapor compositions are always lower to 1.0 K and 0.020, respectively. Checking for the viability for extrapolations in pressure, CPA EoS was also applied to the modeling of the experimental data with very good results. Finally, aiming at examining the model capabilities to describe multicomponent systems, VLE measurements involving two alcohols and the fatty acid ethyl ester mixture obtained from non-edible vegetable oil have been carried out showing the good performance of the predictive models.

“…Methanolysis was observed off-line at a particular sample frequency using gas chromatography-mass spectrometry (GCMS-QP2010). By using GC-mass spectrometry tools and conducting sample analyses, the COSMEs were initially found 14,15 . The methanolysis byproduct was then put through a separating funnel following the reaction.…”

In this study, the acid-alkaline transesterification of refined coconut seed oil (RCOSO) to fatty acid methyl ester was followed by the production of a trimethylolpropane-based thermosensitive biolubricant using potassium hydroxide, and its physicochemical characteristics were evaluated. The American Standard Test for Materials (ASTM) was employed to ascertain the biolubricant's pour point and index of viscosity, which were found to be -4 oC and 283.75, respectively. The opposite connection between lubricant viscosity and temperature was shown by the measured viscosities at varied transesterification to be transformed into biodiesel. Following this, a biolubricant was created by further transesterifiedtemperature. The ester group is verified by comparing the Fourier Transfer Infra-red (FTIR) spectra of the biodiesel and the biolubricant between absorption bands (1755.07-1737.21 cm-1). Gas chromatographic data shows that sweet almond oil contains 71.725 % unsaturated fatty acids for use as a biolubricant, 53.478 % more unsaturated fatty acids than saturated fatty acids, and 9.52 g iodine per 100 g of oil sample more than unsaturated glycerides. At 31.44 and 45.93 %, respectively, linoleic acid made up the majority among the fatty acids in the oil and synthetic biolubricant. In addition, palmitic, linoleic, and oleic acids were present in the biolubricant and coconut oil. The biolubricant's characterization results correlated highly with the ISO VG-32 standards, suggesting that it has the capacity to serve as light gear oil.

“…In another comparative study, silica gel as an adsorbent performed better than rice hull in the purification of biodiesel by reducing FFA . A similar adsorbent in three different forms was employed for biodiesel purification, but the results in case of Jatropha biodiesel were poor compared with biodiesel produced from other feedstocks . A comparative study on different adsorbents suggested that inorganic adsorbents resulted better for purification of crude biodiesel produced using alkaline transesterification for soybean oil.…”

Biodiesel is a promising alternative to conventional fuels. Research on biodiesel has vast experimental findings, but the outcomes are not always unidirectional.The sequence of unit operation for various transesterification processes is studied. The review work emphasizes on the separation and purification of Jatropha-derived biodiesel. The study on the downstream processes of alcohol recovery, glycerol-rich and biodiesel-rich phase separation, and biodiesel purification techniques is the main part of this paper. The biodiesel purification includes wet and dry washing and membrane techniques. The purpose of the review is to find separation techniques that are less energy-intensive and environmentally friendly purification processes for biodiesel production from Jatropha. The strategies to reduce the cost of biodiesel production from Jatropha are discussed. The Jatropha biodiesel possesses huge potential as one of the alternative energy sources for commercial exploitation in India.
