Abstract
Description
technical field
[0001] The invention uses low-cost waste oil with high acid value as a raw material to prepare biodiesel pre-esterification and acid reduction technology, and belongs to the fields of waste reuse and circular economy. It specifically relates to an energy-saving and high-efficiency high-acid-value waste oil glycerin non-catalyzed esterification and acid-reducing continuous production process. Background technique
[0002] As the reserves of traditional petrochemical energy are dwindling, new renewable energy is getting more and more attention. As a substitute for petrochemical diesel, biodiesel has attracted widespread attention from all over the world because of its excellent performance and environmental friendliness. As biodiesel is a renewable clean energy, the development of biodiesel industry is of great significance to protect the environment and reduce dependence on petroleum.
[0003] Biodiesel is fatty acid methyl ester (FAME) or ethyl ester fuel ...
