In this work, it was made a study of biodiesel synthesis by transesterification reaction from Jatropha Curcas Lineu Oil (“Mpuluka”) with methanol in the presence of NaOH. First of all a seed treatment and a granulometric study were carried out and it was concluded that the oil content and yield obtained from the extraction do not depend on the particles size of the seed. The Jatropha Curcas oil was obtained by means of a Soxhlet extraction system, using n -hexane. The oil content obtained was 45,32% and its yield was 90,88%. The physicochemical properties analysis of the oil indicates a high acidity index. For this, the synthesis of biodiesel was carried out using two steps: pre-treatment of crude oil before transesterification reaction and the esterification of crude oil followed by transesterification. The best yield in biodiesel (≈60%) was obtained with the molar ratio (oil/alcohol):1/6. The biodiesel obtained falls within admissible limit values of the international quality standards defined by ASTM_D and EN / ISO.

“…Biodiesel is a monoalkyl ester of long-chain fatty acids that can be produced from renewable biological feedstock: vegetable oils, nonedible oils, animal fats, or waste oils (Al-Sakkari et al, 2017b;Dhawane et al, 2019). Different edible oils were used for biodiesel production such as soybean oil, rapeseed oil, and palm oil (Lam and Lee, 2011;Colombo et al, 2019;Essamlali et al, 2019;Raman et al, 2019). However, waste vegetable cooking oil and nonedible oils are more promising as a feedstock due to their low cost compared to edible ones (Mardhiah et al, 2017).…”

Comparative Technoeconomic Analysis of Using Waste and Virgin Cooking Oils for Biodiesel Production

This study aims to provide the technoeconomic aspects of two clean processes for biodiesel production. The first process utilizes waste cooking oil as a feedstock and potassium hydroxide as a homogeneous catalyst. The second process uses cement kiln dust heterogeneous catalyst and virgin soybean oil. A comparison was performed between the results of the technical and economic assessments to determine the more feasible process. Theoretical purities of biodiesel and glycerol obtained upon conducting the simulation of both processes are high, i.e., 99.99%. However, the homogeneous process is economically superior as its payback period is slightly more than 1 year while the return on investment is higher than 74%, and the unit production cost is USD 1.067/kg biodiesel. Sensitivity analysis revealed that the profitability of biodiesel production is very sensitive to the feedstock price and recommends shifting toward waste vegetable oils as a cheap feedstock to have a feasible and economic process.

“…This renewable energy source is produced by transesterification of a triglyceride such as vegetable oil or animal fat with a short chain alcohol (methanol or ethanol) in the presence of an acid, base, or enzyme catalyst 9,10 . Early researches on biodiesel feedstocks focused on the oil extracted from plants such as rapeseed 11 , soybean 12 , and coconut oil 13 but because of food versus energy issue 14 , attention is now directed towards the use of second generation biofeedstock such as algae 15 , jatropha 16 , rubber seeds 17 , and other non-edible oil sources 18,19 . The competitive nature of biodiesel against petroleum-based diesel is usually limited by the nature of feedstock, synthetic process, and biodiesel purification technique 17,20,21 .…”

This research investigation assessed the potential of choline chloride-based deep eutectic solvents (DESs) in removing impurities from lumbang (Aleurites moluccana)-derived biodiesel. Lumbang oil (56% wt.) which contained about 6.5% free fatty acids was converted into biodiesel through direct acid-base catalyzed reaction. Three different DESs were prepared in a 1:2 (choline chloride:glycerol, ChCl:Gly), 1:2 (choline chloride:ethylene glycol, ChCl:Eg), and 1:2:2 (choline chloride:glycerol:ethylene glycol, ChCl:Gly:Eg) molar ratios. The crude biodiesel was purified with DESs in a 1:1 and 2:1 DES-biodiesel molar ratios. The results of the investigation showed variations in the extraction efficiencies of the three DESs. Binary DESs (DES1 and DES2) successfully fulfilled the standard limits for biodiesel (ASTM D6751; EN 14214) with ChCl:Eg DES (1:2) in a 1:1 DES:biodiesel molar ratio exhibiting maximum removal. Physicochemical characterization of the purified biodiesel showed a decrement in impurities with maximum removal efficiencies of 98.0% (methanol), 89.0% (total glycerides ), and 99.9% (unreacted triglycerides). The decrease in glyceride impurities was reflected in the decrease of kinematic viscosity and enhancement of fatty acid methyl ester. These results demonstrated the effectivity of choline chloride-based deep eutectic solvents in improving the economic viability of lumbang biodiesel as green alternative fuel.
