What Catalysts are Typically Used with Expeller Pressed Oils?
The choice of catalyst depends on the specific catalytic process and desired outcome. In the transesterification process for biodiesel production, common catalysts include alkali catalysts (e.g., sodium hydroxide or potassium hydroxide), acid catalysts (e.g., sulfuric acid), and enzymatic catalysts (e.g., lipases). Each type of catalyst has its advantages and disadvantages in terms of reaction rate, selectivity, and environmental impact.
