How do you make Jatropha seed oil?
How do you make Jatropha seed oil?
Different methods can be used to obtain Jatropha oil from its seeds, but the common methods used for the extraction of the oil include mechanical pressing, supercritical fluid extraction,and solvent extraction. Mechanical extraction is the most widely used method.
How biodiesel is produced from Jatropha?
The production of the biodiesel was done with standard materials and under standard conditions which made the production a hitch-free one. 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.
How do you extract biodiesel?
Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. Bioethanol is an alcohol made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as corn or sugarcane.
How do you extract oil from oil seeds?
Oil extraction methods from oil seeds include conventional methods (solvent and mechanical extraction) and nonconventional or improved techniques (supercritical fluid extraction, ultrasound, microwave, and enzyme assisted extraction.
Which method is used for 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.
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.
Is Jatropha a vegetable oil?
The chemical composition of Jatropha curcas oil is given below- It is significant to point out that, the non-edible vegetable oil of Jatropha curcas has the requisite potential of providing a promising and commercially viable alternative to diesel oil since it has desirable physicochemical and performance …
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.
How is algae oil extracted?
The oil can be extracted from algae using a mechanical press, as seen in figure 1. This process—which forces the algal paste into a nozzle that removes oil and expels much drier biomass—can extract up to 70% of the algal oil, but generally requires a dry algae feedstock. Dry algae is the product of dewatering.
How are biofuels harvested?
Biofuels are combustive fuels made from recently harvested plants. They work much like fossil fuels: they burn when ignited, releasing energy that can be converted to motion in a car, or heat for a house. Biofuel can be sourced from a number of different crops, as well as excess plant matter from other industries.
