Introduction Three general types of reactors are used for biodiesel production: batch reactors, semi-continuous-flow reactors, and continuous-flow reactors. The batch process is inexpensive, requiring much less initial capital and infrastructure investment. It is flexible and allows the user to accommodate variations in feedstock type, composition, and quantity. The major drawbacks of the batch process include … Read More

When a feedstock contains less than 3% or 4% FFA, most people just add extra catalyst, let the FFAs convert to soap, and then remove the soap. From 3% or 4%, up to 10% or 15% FFAs, a common approach is to use vacuum distillation to remove the FFAs from the oil. Then the oil … Read More

Oilseed Crops for Biodiesel Production Biodiesel can be produced from a wide variety of oilseed crops and animal fats. In Europe, rapeseed oil is the major biodiesel feedstock. In the United States, soybeans are the dominant biodiesel feedstock. Soybeans Soybeans produce approximately 1.5 gallons of oil per bushel. U.S. farmers produced a record-breaking yield in 2009 of … Read More

Biodiesel is usually preferred over SVO and WVO because the chemical reaction converts the oil or fat into compounds that are closer to the hydrocarbons found in regular diesel fuel. The chemical reaction that converts a vegetable oil or animal fat to biodiesel is called “transesterification.” This is a long name for a simple process … Read More

The 2020 rapeseed harvest will likely once more be lower than average, but this is not due to shrinking demand, according to Germany’s Union zur Förderung von Oel- und Proteinpflanzen (UFOP), referring to the German biodiesel industry’s feedstock requirements. In 2019, the industry produced 3.4 million tons (1.02 billion gallons) of biodiesel, of which about … Read More

The EU announced that it will impose a five-year countervailing duty on biodiesel imports from Indonesia. The EU has tentatively imposed an additional 8% to 18% countervailing duty on biodiesel imports from Indonesia. This may affect Indonesia ’s biodiesel consumption policy, which is closely related to palm oil stocks. It is understood that after nearly … Read More

According to the news on December 4, a senior official from the Indonesian Ministry of Energy and Mineral Resources said that Indonesia plans to start using palm oil to produce green diesel by 2022, with an estimated output of 3.7 million kiloliters. Indonesia, the world’s largest palm oil producer, wants to develop green diesel, the … Read More

A bottle is the raw material of turbid trench oil, and a little impurity can be seen at the bottom of the soy sauce-colored liquid. A bottle is a colorless and odorless biodiesel sample. I saw two very different samples of oil. What is the connection between the two? The person in charge of the … Read More

Recently, the Brazilian government announced that it plans to increase the minimum biodiesel in diesel fuel in less than one year and increase it by 1 percentage point by 2023, thereby increasing demand for soybeans. After the biodiesel blending ratio increased from 10% to 11% last September, Brazil will increase the minimum blending ratio of … Read More

Indonesia will roll out B30 biodiesel, a fuel blend with a bio-content of 30 percent, in January 2020. JAKARTA: Mr. Rudi pulled up next to a pump in a petrol station in Jakarta. He lifted a grey nozzle and filled up his truck with palm oil-based B20 biodiesel. At 5,150 rupiah (US$0.37) a liter, the … Read More
