METHOD FOR CONTINUOUSLY PREPARING A SACCHARIFIED SOLUTION FROM SEAWEED

摘要

The present invention relates to a method for continuously preparing a saccharified solution from seaweed, and more particularly, to a method for continuously preparing hydrolysate from seaweed, which comprises the following steps: grinding raw seaweed together with a sulfuric-acid solution using a wet grinder in order to produce ground slurry; injecting the ground slurry into a continuous saccharification device including a mono pump and a reaction tube; and producing a saccharified solution including monosaccharides using a hydrolysis catalyst by means of a continuous saccharification process in the reaction tube. The present invention also relates to a method for producing biofuel using the saccharified solution. The method for preparing a saccharified solution by means of a continuous saccharification process according to the present invention produces an amount of fermentable sugars similar to the amount of the fermentable sugars produced by the saccharification process of a conventional batch method, however the method of the present invention inhibits or minimizes the production of HMF, levulinic acid, formic acid, and the like, which act as a fermentation inhibitor, thereby maximizing the production yield of biofuel using the saccharified solution obtained from seaweed.
