“biofuel”的概念、定义、翻译、参考文献-科学参考

biofuel

Chemistry

A gaseous, liquid, or solid fuel that contains an energy content derived from a biological source. The organic matter that makes up living organisms provides a potential source of trapped energy that is beginning to be exploited to supply the ever-increasing energy demand around the world. An example of a biofuel is rapeseed oil, which can be used in place of diesel fuel in modified engines. The methyl ester of this oil, rapeseed methyl ester (RME), can be used in unmodified diesel engines and is sometimes known as biodiesel. Other biofuels include biogas and gasohol.

Chemical Engineering

A gaseous, liquid, or solid fuel that contains carbon derived from a biological or organic source. There is an increasing interest in the use of biofuels in the quest for alternative sources and forms of energy. Examples include biogas, biodiesel derived from plants, and bioethanol from crops such as maize and sugar beet.

Biology

A gaseous, liquid, or solid fuel that contains an energy content derived from a biological source. The organic matter that makes up living organisms provides a potential source of trapped energy that is increasingly being exploited to supply worldwide energy demand. Biofuels are claimed to have a lower ‘carbon footprint’ than fossil fuels, and thus contribute less to the greenhouse effect. However, such claims are often exaggerated, and there is concern that biofuel crops are replacing food crops, with adverse implications for food security, especially in poorer countries. An example of a biofuel is rapeseed oil, which can be used in place of diesel fuel in modified engines. The methyl ester of this oil, rapeseed methyl ester (RME), can be used in unmodified diesel engines and is sometimes known as biodiesel. Other biofuels include biogas and gasohol.

Geography

Any liquid fuel derived from plant materials, including biodiesel which can be made from vegetable oils such as palm oil, soy, or rapeseed oil. ‘There have been two consequences of this change in land use. Firstly, worldwide, less land is being used to produce food at a time when the world population continues to grow. Secondly, as demand and prices have risen for crops such as palm oil, new land has been cleared to start plantations. The land that is being cleared in countries such as Indonesia and Malaysia is often rainforest or other precious environments where plant and animal diversity is high and indigenous people live traditional lives in harmony with the delicate ecosystems’ (Royal Geographical Society website).
