Biodiesel is briefly defined as a renewable fuel derived from vegetable oils or animal fats. Similarly, the American Society of Testing and Materials (ASTM) defines biodiesel as mono‐ alkyl long-chain fatty acids esters derived from fatty renewable inputs, such as vegetable oils or animal fats. The term “bio” refers to its origin from biomass related resources, in con‐ trast to the traditional fosil-derived diesel, while the term “diesel” refers to its use on en‐ gines; as a fuel, biodiesel is typically used as a blend with regular diesel. To date, biodiesel is well recognized as the best fuel substitute in diesel engines because its raw materials are re‐ newable, and it is biodegradable and more environmentally friendly; biodiesel probably has better efficiency than gasoline and exhibits great potential for compression-ignition engines. |
