What You'll Learn
Renewable diesel is made from fats and oils
Renewable diesel is a sustainable fuel that is chemically similar to petroleum diesel but does not rely on fossil fuels. Instead, it is made from fats and oils, such as soybean oil, canola oil, and vegetable oils. It can also be made from animal fats, waste vegetable oils, and used cooking oils. These feedstocks are treated to remove impurities and then undergo a process called hydrotreating, where they are reacted with hydrogen under high temperatures and pressures in the presence of a catalyst. This process removes oxygen from the feedstocks and separates the water. The next step is isomerization, which changes the structure of the molecules to ensure compatibility with existing engines and infrastructure, especially in cold weather. The final step is fractionation, where the product is separated into its finished form.
The use of renewable diesel offers several benefits. Firstly, it is a replacement for diesel and can be used on its own or blended with any amount of petroleum diesel. Secondly, it reduces carbon emissions and improves air quality. An NREL study found that renewable diesel reduced carbon dioxide and nitrogen oxide emissions compared to petroleum diesel. Additionally, it has a lower carbon intensity, with a life cycle greenhouse gas emissions reduction of up to 80% compared to traditional diesel. Renewable diesel also provides flexibility and compatibility, meeting the ASTM D975 specification for petroleum in the United States. This allows it to be used in existing diesel engines and infrastructure without any modifications.
The production of renewable diesel has seen a recent boom, with new plants being established, particularly in western states. This growth has impacted the price of fats and oils used as feedstocks. The United States continues to import from international producers, such as Neste, which has plants in several European countries and Singapore. The increased production of renewable diesel has also led to its widespread adoption, with nearly all domestically produced and imported renewable diesel being used in California due to economic benefits under the Low Carbon Fuel Standard.
The process of making renewable diesel from fats and oils involves several steps, and the final product is a sustainable and clean fuel that can be used in existing diesel engines. The production of renewable diesel offers environmental benefits, such as reduced emissions and lower carbon intensity, making it a preferred choice over traditional diesel.

Biodiesel is made from vegetable oils and animal fats
Biodiesel is a type of diesel fuel that is made from vegetable oils, animal fats, and waste grease. It is distinct from renewable diesel, which is made from non-petroleum renewable resources such as natural fats, vegetable oils, and greases. Biodiesel is produced by a process known as transesterification, which converts organic fats and oils into fatty acid alkyl esters. This process involves reacting fats and oils with alcohols and catalysts to form biodiesel and glycerin. The most common feedstocks for biodiesel production in the US include soybean oil, animal fats from meat processing plants, used cooking oil, and yellow grease from restaurants.
Biodiesel is a feasible substitute for fossil diesel as it is made from renewable resources and can be used in its pure form or blended with petroleum diesel. However, the use of edible vegetable oils in biodiesel production raises ethical concerns, as using arable land, water, and fertilizer for fuel instead of food affects food prices and sustainability. Additionally, the use of vegetable oils in biodiesel production may not be sufficient to meet today's diesel requirements.
Biodiesel made from animal fats has several advantages over vegetable oil-based biodiesel. For instance, biodiesel blends made from lard, beef tallow, and chicken fat have lower nitrogen oxide (NOx) emission levels compared to blends produced from soy oil.
In summary, biodiesel is a renewable diesel fuel made from vegetable oils and animal fats. It offers a sustainable alternative to fossil diesel, but the use of edible vegetable oils in its production presents ethical and sustainability challenges. Biodiesel from animal fats may provide a solution to these issues while also reducing nitrogen oxide emissions.

Renewable diesel is chemically similar to petroleum diesel
Renewable diesel is a fuel that is chemically similar to petroleum diesel but is 100% renewable and sustainable. It is made from fats and oils, such as soybean oil or canola oil, and is processed to be chemically the same as petroleum diesel. It meets the ASTM D975 specification for petroleum in the United States, allowing it to be used in existing infrastructure and diesel engines without any blending or modification to equipment.
The production process for renewable diesel is similar to that of petroleum diesel, involving hydrogenation and other methods such as hydrotreating, gasification, pyrolysis, and biochemical and thermochemical technologies. This makes renewable diesel chemically equivalent to petroleum diesel, and it can be seamlessly blended, transported, and co-processed with petroleum diesel. The hydrogenation process also ensures that renewable diesel doesn't contain oxygen, avoiding issues related to freezing temperatures and storage.
One of the key benefits of renewable diesel is its positive environmental impact. It reduces carbon intensity and emissions of greenhouse gases compared to petroleum diesel. For example, using a gallon of renewable diesel emits less than 10 lbs of greenhouse gases, while a regular gallon of diesel fuel emits more than 30 lbs. It also burns cleaner, improving air quality without sacrificing power or performance.
Renewable diesel is a flexible fuel that can be used as a full replacement for diesel or blended with any amount of petroleum diesel. It can be made from multiple feedstocks, including vegetable oils, animal fats, and recycled biomass-based diesel fuels. The use of renewable diesel can help fleets meet sustainability goals and reduce costs, as seen in California with its Low Carbon Fuel Standard.

Biodiesel is blended with petroleum diesel
Biodiesel is a renewable fuel made from vegetable oils and/or animal fats. It is produced by a process known as transesterification, which converts organic fats and oils into fatty acid alkyl esters. This process introduces oxygen into the fuel, which can cause issues with freezing temperatures, separation during storage, and higher emissions.
Petroleum diesel, on the other hand, is a conventional fossil fuel made from crude oil, hydrocarbons, organic compounds, and small amounts of metal. To address the challenges posed by the high viscosity of vegetable oils compared to petroleum diesel, attempts have been made to blend biodiesel with petroleum-derived diesel fuel.
Biodiesel can be blended with petroleum diesel in several ways. One method is to mix the two fuels in tanks at the manufacturing point before delivery to tanker trucks. Another approach is splash mixing, where specific percentages of biodiesel and petroleum diesel are added directly into the tanker truck. In-line mixing involves the simultaneous arrival of the two components into the tanker truck. Metered pump mixing utilizes meters for both fuels to achieve the desired blend ratio.
Biodiesel blends with petroleum diesel typically range from B6 to B20, with B5 (5% biodiesel) and B20 (6-20% biodiesel) being common. Biodiesel has beneficial lubricating properties and can prolong the life of certain engine components. However, it also has strong solvent properties, so care must be taken to avoid clogging fuel filters and pipes.
While biodiesel is a renewable alternative to petroleum diesel, another option is renewable diesel, which is also made from natural fats, vegetable oils, and greases. Renewable diesel undergoes a different production process, resulting in a fuel that is chemically similar to petroleum diesel but without relying on fossil fuels. It can be used as a direct replacement for diesel or blended with petroleum diesel.
