How is Jatropha oil extracted?
The extraction process of jatropha oil from jatropha curcas can be accomplished either chemically with solvents, mechanically or hydraulically using a press. Generally, extraction of oil using a solvent extraction technique is more efficient, and it obtains the maximum oil yield.
What are the different methods of oil extraction?
Oil is extracted by three general methods: rendering, used with animal products and oleaginous fruits; mechanical pressing, for oil-bearing seeds and nuts; and extracting with volatile solvents, employed in large-scale operations for a more complete extraction than is possible with pressing.
How do you convert Jatropha oil to biodiesel?
The Jatropha refined oil was then converted into biodiesel via a transesterification process. The transesterification process was done by adding NaOH (0.4% wt of oil) which was used as catalyst, and methanol (12.5% wt of oil) into the refined oil.
What is Jatropha oil used for?
Jatropha oil has been used in India for several decades as biodiesel for the diesel fuel requirements of remote rural and forest communities; jatropha oil can be used directly after extraction (i.e. without refining) in diesel generators and engines.
How do you make mint oil out of mint leaves?
For peppermint oil
- Crush or muddle fresh peppermint leaves in a glass jar with a tight lid.
- Cover the leaves with olive or grapeseed oil. Close the jar and shake.
- Store for three days. Strain into a bowl and discard the leaves.
- Pack the jar with fresh leaves, pour the oil back in the jar and cover with fresh oil.
What is plant oil extraction?
A very common method of extracting essential oils is a low-heat steam distillation process. In this process, pressurized steam is circulated through plant material. The steam carries the volatile aromatic compounds from the plant into a collecting tube, where the steam is cooled and condensed back into water.
Which solvent is used for oil extraction?
n-hexane
The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents.
