Method for Biodiesel Manufacturing using Non-catalytic Esterification Reaction from Microalgae

摘要

The present invention relates to a method for manufacturing bio-diesel by extracting lipid from microalgae, which is not processed by a drying process, using alcohol without using a catalyst, and performing non-catalytic esterification reaction and trans-esterification reaction. According to the present invention, the method for manufacturing bio-diesel from microalgae by using alcohol does not apply a process for drying microalgae and thus requires low energy consumption and low process costs needed for facilities. Since a strong acid catalyst such as sulfuric acid, hydrochloric acid, or nitric acid is not used, the method for manufacturing bio-diesel generates little environmental burden such as waste water treatment. Accordingly, the method for manufacturing bio-diesel can reduce production costs of bio-diesel based on microalgae.
