In this study, the methanolysis of mixed crop oils (Hevea brasiliensis and Jatropha curcas L.) was investigated. Due to the oils contain high impurities, a particular pre-treatment of which was carried out. For alkali-catalyzed methanolysis, few parameters (such as: molar ratio, catalyst percentage, and reaction time) were studied. The results showed that the methanolysis optimum conditions were 5.5 of molar ratio, 0.9% w/w of catalyst, and 60 minutes of reaction time with the highest yield of 98.9%. The kinetics study indicated that first order reaction mechanism with reaction rate constant and activation energy were 1.5 × 10 −2 minute −1 and 23.93 KJ•mol −1 respectively. As fuel, the physicochemical properties of biodiesel met the standard values required by ASTM D6751.

The present study focuses potentiality of biodiesel production in Bangladesh from non-edible oil. The increasing demands of energy are consumed by using fossil fuels which are non-renewable and will be depleted within 150 years from now if this growth rate stays but if this rate increases further the depleting time will decrease from the estimated one. Because of low reservation of crude oil, Bangladesh has to import oils from other countries, these costs a lot. About 95% of these demands can be meted through biodiesel. Biodiesel prepared from both edible and non-edible oils. After meeting demands of edible oil of the country it is impossible to produce biodiesel from edible oils. But it is possible to meet the biodiesel demand of the country almost 100% through non-edible oil derived biodiesel. Arable lands of Bangladesh can't be used for the growing purposes of non-edible oil seeds, but if rail and road sides are used there is no need for extra lands. After surveying lands for this purpose it seems that Bangladesh can get a total amount of 47750 Km of road and rail side areas for the cultivation of non-edible seeds. Among these forest seeds Nageswar, Pitraj, Sultana champa Ponyal, Rata, Oil palm, Chaulmoogra, Bakul, Kusum, jaina have sufficient oil content along with plenty of growth in Bangladesh. Cultivating these seeds 1100000 tones of biodiesel can be produced on the basis of their oil content and yield. Which decreases the amount of imported crude oil as well as meets the oil demand of the country, thus Bangladesh can be able to save about $6 billion per year means a great economic savings that can be used for the development of the country.

“…To reduce FFA, different pretreatment methods were applied previously. Among them steam distillation, utilization of solid base catalyst, extraction by alcohol and acid catalyst esterification were investigated (Morshed et al, 2011;Xu et al, 2007). Comparing different aforementioned pretreatment methods, acid catalyst esterification is preferable one.…”

“…Steam distillation is also not viable for high temperature operation. For the low solubility of FFA in alcohol, the alcohol extraction process is an expensive method (Morshed et al, 2011).…”

Biodiesel derived from non edible sources is a potential eco-friendly substitute to petroleum fuel. Acid-catalysed esterification was applied to reduce free fatty acid (FFA) content of oil to zero followed by base-catalyzed transesterification to convert esterified product to its mono-esters and glycerol. The major factors affecting the conversion efficiency of these two processes such as amounts of solvent and catalyst, reaction temperature, and reaction time were optimized. The physical properties and heating value of Mahogany Seed Oil (MSO) and MSO diesel are evaluated and compared with that of commercial diesel. FTIR and 1H NMR spectrum of MSO and MSO biodiesel confirmed the conversion of MSO to biodiesel. The oxidation stability of MSO biodiesel oil was also studied. The study affirms the production of biodiesel from MSO as a renewable alternative to the diesel fuel.
