topic 10 Flashcards
Ethanol
Ethanol is a renewable, domestically produced alcohol fuel made from plant material, such as corn, sugar cane, or grasses.
Biodiesel
Biodiesel is a domestically produced, renewable fuel that can be manufactured from vegetable oils, animal fats, or recycled restaurant grease for use in diesel vehicles.
Cellulosic Biofuels
Cellulosic ethanol is a biofuel produced from wood, grasses, or the inedible parts of plants.
Algae-based Fuels
Algae-based Fuel is an alternative to fossil fuel that uses algae as its source of natural deposits.
Drop-in Fuel
One of the most popular definitions is that drop-in fuels are those renewable fuels, which can be blended with petroleum products, such as gasoline, and utilized in the current infrastructure of pumps, pipelines and other existing equipment.
Feedstock
Total biomass inputs to the production of biofuels.
Rapeseed
Rapeseed oil is used as diesel fuel, either as biodiesel, straight in heated fuel systems, or blended with petroleum distillates for powering motor vehicles.
Jatropha
Its oil seeds offer feedstock for Jet fuel.
Energy content
Energy content is the amount of energy produced by a unit of a fuel ; energy/unit (anything)
GHG Balance
The balance between emissions of GHG and the removal of the gas from the atmosphere
RFS/ RFS 2
Renewable Fuel Standard
RIN
Renewable Identification Number
Blend Wall
The Renewable Fuel Standard (RFS) has threatened to force petroleum refiners to mix a blend of gasoline that cars can’t use. The threat of the limit is known as the “blend wall”.
Food vs. Fuel
Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply.
Co-Products
Co-products (which involve similar value to the main product. E.g. bio-fuel and Distillers grains, glycerol), by-products (which result in smaller value. Electricity and heat), and waste products (which provide little or no value)
