Which non edible oilseeds are used for making biodiesel?
Jatropha, rubber seed, jojoba, tobacco seed, sea mango, neem, candlenut, mahua, karanja, yellow oleander are examples of non-edible plant sources which make up the 2nd generation feedstock. Moreover, animal fats sources like poultry fat, pork lard, and beef tallow can be utilized as a source for producing biodiesel.
How do you convert any given oil into biodiesel?
Base-catalyzed transesterification reacts lipids (fats and oils) with alcohol (typically methanol or ethanol) to produce biodiesel and an impure coproduct, glycerol. If the feedstock oil is used or has a high acid content, acid-catalyzed esterification can be used to react fatty acids with alcohol to produce biodiesel.
Why is non edible feedstock preferred for biodiesel production?
Oils from non-edible resources are unsuitable for human consumption because of the presence of some toxic components (Bankovic-Ilic et al., 2012). Non-edible vegetable oils are therefore expected to help the biodiesel to be competitive in price as compared to the use of food-grade vegetable oils.
What is the process of conversion of vegetable oil into biodiesel mentioned?
Biodiesel is produced from vegetable oils, yellow grease, used cooking oils, or animal fats. The fuel is produced by transesterification—a process that converts fats and oils into biodiesel and glycerin (a coproduct).
What are the edible and non edible biodiesel sources?
An interesting case of biodiesel production from edible vegetable oils is India, where about 46% of the needed amounts for the domestic requirements are imported [23]. Therefore, non-edible oils from jatropha, karanja, neem, mahua and other plants are the only possibility for biodiesel production.
What is the meaning of non edible oil?
Non-edible oils are not suitable for human food because of the presence of some toxic components. Non edible oils are mainly wastage & By-Products of Edible/ Cooking oil & Refinery Industry and oils of some non edible species seeds. Major Non edible oil seeds are Mahua, karanja, Jatropha, Castor and Neem.
What is the process of transesterification?
Transesterification is the process in which fat or oil reacts with an alcohol to form esters and glycerol. A catalyst is used to improve the reaction rate and yield. Because the reaction is reversible, excess alcohol is used to shift the equilibrium to the product side.
What is meant by non edible oil?
What is non edible oil?
What is edible and non edible oil?
These are based on vegetable sources (oilseed grains and plant fruits). These can be vegetable oils, petroleum oils or animal fat. Edible oils are mainly used for direct human consumption as food intake. Non-edible oils have industrial usages such as fuel and biofuel, or in producing soap, detergent, paint, etc.
What is the difference between edible and non edible oil?
Edible oils are mainly used for direct human consumption as food intake. Non-edible oils have industrial usages such as fuel and biofuel, or in producing soap, detergent, paint, etc. Edible oils contain various nutritional elements and thus are healthy and hygienic.
Which catalyst is used in transesterification?
The sulphonic-acid–modified mesostructured catalyst is used in the transesterification reaction, achieving a conversion as high as 100%. However, the high concentration of methanol has been found to be detrimental to the catalytic activity [99].
What is transesterification process for biodiesel production?
Transesterification is a chemical reaction used for the conversion of triglycerides (fats) contained in oils, (Feedstocks) into usable biodiesel. Biodiesel produced by the process of transesterification has a much lower viscosity, making it capable of replacing petroleum diesel in diesel engines.
What is difference between edible oil and non edible oil?
What is difference between edible and non edible?
Ask the students what they think the words ‘Edible’ and ‘Non-edible’ mean. If they do not know, explain that edible means things you can eat and non-edible means things you cannot eat.
What is the difference between edible oil and non edible oil?
What does non edible oil mean?
How is cooking oil converted to biodiesel?
Each catalyst used to convert cooking oil into biodiesel results in different levels of complexity, cost, energy consumption, and feasibility. According to the American Society for Testing and Materials (ASTM), biodiesel is defined as a “fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats”.
What is biodiesel and how is it made?
According to the American Society for Testing and Materials (ASTM), biodiesel is defined as a “fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats”.
Can WCO be converted to biodiesel?
In the case of an oil with a higher FFA content, a removal pretreatment would have been necessary to account for the use of an alkali catalyst and its sensitivity to FFA contamination. Overall, the catalyst successfully converted WCO into an acceptable biodiesel by the means of a cheap and efficient process.
Is biofuel a good alternative to diesel fuel?
The use of biofuel as a substitute for petroleum diesel is a valuable solution to the inescapable global issues regarding energy shortage and environmental pollution.
