ok B ces Match each biofuel with its source materials. Corn or cellulose (eg. switch grass, wood, cornstalks) Kerosene Ethanol Decomposing organic matter and sewage Coal Biodiesel Biogas Vegetable oils and nut oils Oil Biocell
The correct answer and explanation is:
Here are the correct biofuel matches along with explanations:
- Corn or cellulose (e.g., switchgrass, wood, cornstalks) → Ethanol
Ethanol is a type of alcohol fuel commonly made from crops that are high in starch or sugar. In the U.S., corn is the primary source used to produce ethanol, as it is rich in carbohydrates. Cellulosic ethanol, on the other hand, is derived from the cellulose in plant material such as switchgrass, wood, and cornstalks. These materials are broken down into sugars that are fermented into ethanol. The process is more complex for cellulose-based ethanol due to the need for specialized enzymes to break down the plant fibers. - Kerosene → Oil
Kerosene is a type of fuel that is derived from crude oil. It is a liquid hydrocarbon fuel used primarily for jet engines and heating. Although not traditionally considered a biofuel, there are advancements in bio-based kerosene, often produced from plant oils or algae. This bio-kerosene is made to replicate the properties of fossil fuel-derived kerosene. - Decomposing organic matter and sewage → Biogas
Biogas is produced through the anaerobic digestion of organic matter, which includes sewage, agricultural waste, food waste, and other biodegradable materials. Microorganisms break down these materials without oxygen, producing methane as the main component of biogas. This methane can be used to generate electricity, heat homes, or as a fuel for vehicles. - Coal → Coal
Coal is a non-renewable fossil fuel, and it is not a biofuel. It is formed from the remains of ancient plants that have been subjected to heat and pressure over millions of years. Although coal can technically be used as a source of energy, it is not considered a biofuel because it does not come from living organisms currently in the biosphere. - Vegetable oils and nut oils → Biodiesel
Biodiesel is a renewable fuel made from vegetable oils, animal fats, or algae oils. It is commonly produced from soybeans, canola, and palm oils, as well as oils from nuts like peanuts or algae. The oils are chemically processed through a reaction with alcohol (usually methanol) to create biodiesel, which can be used in diesel engines. - Oil → Biocell
Biocell typically refers to bio-based oils that can be converted into various biofuels, including biodiesel, and are derived from plants, algae, or animal fats. These oils are renewable and biodegradable, providing an eco-friendly alternative to petroleum-based oils. These oils are used in various biofuel applications.
Explanation
Biofuels are considered a renewable energy source, typically produced from organic materials like plants or waste. Each biofuel type has distinct sources and processing methods:
- Ethanol is mostly made from crops like corn and other cellulose-rich materials, and it’s used in gasoline engines.
- Biodiesel, derived from vegetable oils and animal fats, can be used in diesel engines, offering a cleaner alternative to petroleum diesel.
- Biogas, produced by the decomposition of organic waste (including sewage), offers a way to generate renewable methane for electricity and heating.
- Kerosene, while mostly derived from crude oil, is also being investigated for bio-based production, especially for aviation fuel.
These biofuels provide an eco-friendly alternative to fossil fuels, reducing greenhouse gas emissions and offering sustainable energy solutions.
