In order to reduce the biodiesel production process "acid residue" and "sodium waste,", the company technical staff and experts conduct a long-term domestic oil research trials and developed a new biodiesel preparation process - Biodiesel non- acid-catalyzed production technology. The process uses a fatty acid containing a large amount of oil, under a certain pressure, temperature and special alloy catalyst pre-esterification reaction with industrial grade glycerol. Generating monoglycerides, diglycerides, triglycerides mixture.
Non-acid catalyzed biodiesel production process advantages:
1. No sulfuric participation in, it does not produce acid residue and sodium waste;
2. High concentrations of byproduct crude glycerin, which conducive distillation industrial products glycerin;
3. Do not use methyl vapor generator, which saves steam and reducing the consumption of methanol.
