How to separate biodiesel from glycerol
Web3 apr. 2024 · For large scale biodiesel producers, crude glycerol can be refined into a pure form and then be used in food, pharmaceutical, or cosmetics industries. For small scale producers, however, purification is too expensive to be performed in their manufacturing sites. Their crude glycerol is usually sold to large refineries for upgrading. Web13 apr. 2024 · It can be seen that homogeneous catalysts cannot be reused or regenerated, which is one of their major disadvantages. The separation of a homogeneous catalyst from products is difficult . Homogeneous catalysts are partially miscible in biodiesel and miscible in glycerol, which results in problems of product separation from the reactant mixture.
