How is Jatropha biodiesel produced?
The jatropha oil was heated to 60°C, and a solution of sodium methoxide (at 60°C) was added to the oil and stirred for 45 minutes using a magnetic stirrer. The mixture was then left to settle for 24 hours. Glycerin, which is the byproduct, was filtered off.
Why Jatropha is suitable for biodiesel production?
Jatropha Curcas is a low-cost biodiesel feedstock with good fuel properties and more oil than other species. It is a non-edible oilseed feedstock. Thus it will have no impact on food prices or the food vs fuel debate.
How much biodiesel is produced from Jatropha?
The biodiesel production from multiple feedstocks reported during the years 2014, 2015 and 2016 was 130,135 and 140 million litres respectively, and was estimated to go upwards of 150 million litres in 2017.
Which part of Jatropha is used in production of biodiesel?
Seeds from the Jatropha curcas plant are used for the production of bio-fuel, a crucial part of India’s plan to attain energy sustainability.
How do you convert Jatropha oil to biodiesel?
The chemical process of converting oil to biodiesel is referred to as transesterification. Transesterification is a process that replaces an alcohol functional group from an ester with another one by reacting vegetable oils with alcohol in the presence of a catalyst. This process converts oil into biodiesel.
What is the catalyst in biodiesel?
Niobia
Niobia supported on silica is used as a heterogeneous catalyst for biodiesel production from waste oil. This catalyst has been observed to be active in both esterification and transesterification, due to the acidic nature of niobia, and it maintains its ability for >100 h without loss of activity [105].

What is the yield of Jatropha in tonnes per hectare per year?
Individual tree yields are reported to range from 0.2 to 2.0 kg of seed annually (Francis, 2005). On an area basis, Openshaw (2000) reports seed yields between 0.4 to 12 tonnes per ha, and Heller (1996) reports yields between 0.1 and 8.0 tonnes per ha.
What is the scientific name of Jatropha?
JatrophaNettlespurges / Scientific name
Jatropha is a genus of flowering plants in the spurge family, Euphorbiaceae. The name is derived from the Greek words ἰατρός (iatros), meaning “physician”, and τροφή (trophe), meaning “nutrition”, hence the common name physic nut. Another common name is nettlespurge.
What is the importance of Jatropha?
The latex of Jatropha contains an alkaloid known as “Jatrophine” which is believed to have anti-cancer properties. It is also used for skin diseases, rheumatism and for sores on domestic livestock [2]. The white latex serves as a disinfectant in mouth infections in children.
Which catalyst is used in synthesis of biodiesel?
Currently, most biodiesel is prepared using alkaline catalysts, such as sodium and potassium methoxides and hydroxides. Industrially, NaOH and KOH are preferred due to their wide availability and low cost. Nonetheless, from a chemical standpoint the active species with both types of catalysts are methoxide ions.
What is the temperature of biodiesel?
The US biodiesel specification, ASTM D6751, requires that the cloud point be reported and that the fuel meet a maximum CSFT test limit of 360 s or 200 s if the expected fuel temperature is -12°C or less.
Which part of Jatropha is economically important?
The plant produces many useful products, especially the seed, from which oil can be extracted; this oil can be used as a feed stock for biodiesel. The extracted oil can also be used for making soap, glue, dye, etc. The leaves, shoot latex, roots and seed oil has medicinal properties.
