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

Fundamentals Principle of oil production by microalgae is the use of micro algae photosynthesis. First, convert the carbon dioxide in the process of chemical production into biomass of micro algae to fix the carbon. Second, convert the carbon material of microalgae into oil via induction reaction. Then, convert the oil in the microalgae cell microalgae and microalgae gasoline to the … Read More

Biodiesel is a kind of fatty acid methyl ester produced by the transesterification reaction of low carbon alcohols of animal and vegetable oils under the action of the catalyst. As a new environmentally friendly renewable alternative fuel, biodiesel has become the research object of scholars in recent decades. Compared with fossil fuels, biodiesel has the advantages of … Read More

Compared with European and American countries, China’s biodiesel industry developed late and started during the Tenth Five-Year Plan period. Some private enterprises mainly used traditional chemical methods to produce biodiesel from waste oils and fats. In 2001, the first biodiesel plant invested by Hainan Zhenghe Bioenergy Company was put into production in Wu’an, Hebei Province, … Read More

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

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

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

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

Advantage: (1) The performance of biodiesel is very similar to that of petroleum diesel. As the fuel of diesel engine, there is no need to modify the engine and the storage of biodiesel is the same as that of petroleum diesel. (2) Biodiesel used as automobile fuel can reduce emissions of carbon dioxide (CO2) by … Read More

There are two methods of production, physical synthesis and chemical synthesis. 1. Chemical synthesis of biodiesel: The chemical synthesis method is to transesterify low-carbon alcohols (mainly methanol or ethanol) with natural oils and fats. After transesterification, long-chain fatty acid esters of low-carbon alcohols can be obtained. The relative molecular weight of the esters can be reduced … Read More
