Biodiesel production from jatropha oil in a closed system

Abstract

Abstract. The use of biodiesel as an alternative fuel is becoming increasingly popular nowadays due to global energy shortage. The interest in using Jatropha as a non-edible oil feedstock is rapidly growing. Biodiesel produced from crude Jatropha oil with NaOH as a catalyst is investigated. Transesterification by methanol is carried out in a closed vessel as a batch system. Factors affecting the process which included the reaction temperature and pressure, reaction time, the molar ratio of methanol to oil and catalyst amount are investigated. The maximum conversion ratio of methyl ester yield of 97.7% was recorded under the conditions of 65 ºC, 1% (by mass) NaOH of the oil mass and 6:1 methanol to oil ratio.

The determination of heterogeneous catalytic performance of Palm Oil Fuel Ash (POFA) in the production of biodiesel via transesterification of Jatropha oil

“…It is also known as a diesel fuel due to the facts that it could yield substantial quantity of oil (1000 barrels of oil per year per sq mile) that can be converted to biodiesel without refining (Kumar & Sharma, 2008;Belewu et al, 2010). The oil from these seeds has low acidity, good oxidation stability, low viscosity and good cold properties (Shaaban et al, 2016). Jatropha plant is a multipurpose tree which can serves as a commercial crop in the production of biodiesel due to the fact that it contains hydrocarbons with 16 to 18 carbon atoms per molecule which is greater than that of conventional fossil fuel.…”

Athmospheric Hydrocracking of Jatropha Oil Using Woodchar Catalyst

“…Jatropha oil has the potential to become a resource of renewable raw material for fuel oil production. The fuel that can be made from Jatropha oil is methyl ester (bio-diesel) (Wardhani & Hidayat, 2014;Shaaban et al, 2016;Folaranmi, 2013). The disadvantage of bio-diesel is cannot be used in the engine with 100% composition, due to can be damaged engine in the long term use (Parawira, 2010).…”
