Magnesium oxide (MGO) is an inorganic compound with a variety of applications. In the production of biological diesel, it plays the following important roles:
- Catalyst:
Magnesium oxide can be used as a catalyst for production of biological diesel. It can catalyze the following reactions:
Esterization of fat and alcohol
Freedfoot fatty acid and alcohol esterization reactions
The catalytic activity of MGO is attributed to its surface alkaline sites. These sites can accept protons in alcohol and promote reactions.
- Adsorption agent:
Magnesium oxide has a strong adsorption ability and can adsorb impurities in biological diesel. This includes:
Free fatty acid
pigment
Phospholipid
Metal ion
Adding these impurities can improve the quality and stability of biological diesel.
- Antioxidant:
Magnesium oxide has antioxidant effects and can help protect biological diesel from oxidation. Oxidation can lead to inferior changes and declines of biological diesel.
- Sap canist:
Magnesium oxide can react with free fatty acid reactions at high temperatures to form soap. This reaction process is called saponification. The mixture after saponification is easy to separate and can remove free fatty acids.
- Classes:
Magnesium oxide can be used as a desiccant to remove water in biological diesel. Water reduces the quality and stability of biological diesel.
- Abrasion agent:
Magnesium oxide can be used as an anti -wear agent by forming a protective film in biological diesel. This can reduce wear and corrosion inside the engine.
- Cost benefits:
Magnesium oxide is a material with high cost benefits. Compared with other catalysts, it has a lower cost.
Summarize:
Magnesium oxide plays a variety of important functions in the production of biological diesel, including as a catalyst, adsorption agent, antioxidant, saponin, desiccant, anti -abrasive and cost -benefit material. This makes it an important additive to improve the efficiency of biological diesel production and product quality.
