Title:
SYSTEM FOR SIMULTANEOUSLY PRODUCING VARIOUS KINDS OF BIOFUELS USING BIOMASS AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/097526
Kind Code:
A1
Abstract:
The present invention relates to a system for simultaneously producing various kinds of biofuels using a biomass and a method for producing same. The system for simultaneously producing various kinds of biofuels using a biomass according to the present invention is characterized by including: a storage tank in which a biomass is stored; an acid-fermentation bath connected to the storage tank and acid-fermenting the biomass supplied from the storage tank, thereby decomposing the biomass into complex organic acids while producing hydrogen at the same time; a solid-liquid separator connected to the acid-fermentation bath and separating a fermented solution supplied from the acid-fermentation bath into solid components and liquid components to perform high purity treatment; an alcohol fermentation bath connected to one side of the solid-liquid separator to produce alcohol by using a volatile organic acid supplied from the solid-liquid separator; and a biogas generation unit connected to the other side of the solid-liquid separator to produce a biogas by using organic residue supplied from the solid-liquid separator. Accordingly, a system for simultaneously producing various kinds of biofuels using a biomass and a method for producing same may be provided, wherein various kinds of energy, including not only existing biogases made of methane gas, but also hydrogen and liquids such as alcohol, may be simultaneously produced.
