The development of biodiesel abroad

Biodiesel was first invented in 1988 by the German company Niel. Biodiesel, with its outstanding “environmental protection” and “reproducibility”, has attracted the attention of the developed countries, especially the resource-poor countries. At present, it has formed three major biodiesel production bases around the rich area of several main oil raw materials, and gradually spread to the world. In … Read More

Biodiesel technology

Biodiesel is a fatty acid methyl ester obtained by esterification and transesterification of animal and vegetable oils with short-chain alcohols such as methanol. It is a renewable and clean energy source. Prospects Brazil is vigorously promoting biodiesel production to reduce oil imports. The US Department of Energy is raising funds to develop biomass energy, requiring … Read More

Biodiesel definition

Biodiesel refines automatic vegetable oils, commonly used in tractors, trucks, ships, etc. It refers to oil crops such as soybean, rapeseed, cotton, palm, etc., wild oil plants and engineering microalgae and other aquatic plant oils and animal fats, food waste oil, etc. as raw material oil can be replaced by transesterification or thermochemical process. Recycled … Read More

Biodiesel Made From Chlorella

Its research purpose and significance Energy is the power of social operation, oil as the most important fossil energy known as the “blood of industry”. In 2016, China’s oil import continued to grow, with the apparent oil consumption exceeding 556 million tons and the foreign dependence reaching 64.4%, an increase of 3.8% compared with 2015. As oil … Read More

The main advantages of biodiesel

The main advantages of biodiesel It has excellent environmental protection characteristics: biodiesel and petrochemical diesel have lower sulfur content and can greatly reduce sulfur dioxide and sulfide emissions after use. Authoritative data show that emissions of sulfur dioxide and sulfides can be reduced by about 30%. Biodiesel contains no aromatic compounds that pollute the environment. … Read More

Immobilized Enzyme Biodiesel Research

1.Preparation of biodiesel by enzyme-catalyzed transesterification Enzyme-catalyzed transesterification is the process of using lipase to catalyze the production of biodiesel under certain conditions. That is to say, under the action of enzymes, substances such as low-level alcohols (methanol or ethanol) are used to replace glycerol in fatty acid glycerides in the oil, so as to produce … Read More

Transportation and Storage of Biodiesel

Introduction Biodiesel that leaves the production plant in good condition can become unacceptable during distribution without proper care and attention. Biodiesel can degrade due to oxidation, contact with water, and/or microbial activity. In general, biodiesel will degrade more quickly than petro-diesel. In one sense, this is a good thing: a biodiesel spill will biodegrade quickly … Read More

Safe Chemical Handling in Biodiesel Production

Introduction Biodiesel is a relatively safe product. It is considered nonflammable and biodegradable. However, the components to make biodiesel can be hazardous in some situations. Biodiesel is made by reacting vegetable oil or animal fat with an alcohol (methanol or ethanol) and a catalyst (sodium hydroxide or potassium hydroxide). Sulfuric and hydrochloric acids are also … Read More

Biodiesel Production Principles and Processes

The process to make biodiesel involves a chemical reaction. This means that the biodiesel industry is a chemical industry. Those involved in making biodiesel must have a good understanding of the underlying chemistry to ensure they are making quality fuel in a safe manner. Biodiesel is an alternative fuel for diesel engines that is produced … Read More

Value-added uses for crude glycerol–a byproduct of biodiesel production

Glycerol is a by-product of biodiesel, soap and fatty acid manufacturing plants, which are now facing sustainability threats and a reduction in prices in the market due to its oversupply as a result of the rapid expansion of biodiesel plants all over the world. The global production and consumption of glycerol, as well as demand … Read More
