PRETREATMENT METHOD OF ALGAE FOR PRODUCTION OF BIOENERGY AND METHOD FOR BIOENERGY USING THEREOF

摘要

PURPOSE: A pretreatment method of algae for the production of bio energy is provided to increase a saccharification yield by effectively separating alginic acid using a simple process and pre-treating a biomass. CONSTITUTION: A pretreatment method of algae for the production of bio energy comprises a step of reacting algae at 110-170 deg. C for 20-70 minutes under the presence of a sodium salt catalyst. The algae comprise kelp. The sodium salt catalyst comprises sodium carbonate. The concentration of the sodium salt is 5-10 wt%. Alginic acid in the algae is decomposed by the reaction. The pretreatment method additionally comprises a step of pulverizing the algae into particles before the reaction. The size of the particle is 8 meshes or greater.
