Question

explain some extraction methods for biodiesel from plants. Also, name plants and their parts from which biodiesel can be obtained.

Answer 1

Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters. It is typically made by chemically reacting lipids such as animal fat (tallow),[1] soybean oil,[2] or some other vegetable oil with an alcohol, producing a methyl, ethyl or propyl ester.

Unlike the vegetable and waste oils used to fuel converted diesel engines, biodiesel is a drop-in biofuel, meaning it is compatible with existing diesel engines and distribution infrastructure. Biodiesel can be used alone or blended with petrodiesel in any proportions.[3] Biodiesel blends can also be used as heating oil.

Answer 2

Answer:

Explanation:

To create bioalcohol, such as ethanol, engineers use yeast and bacteria to break down the starch in corn and other plants. To create biodiesel, refineries use the oil already found in crops such as soybeans [source: Thomas]. These vegetable oils are treated with alcohol and turned into biodiesel.
