20160024535 | ELECTROCHEMICAL DETOXIFICATION METHOD OF WOOD-BASED HYDROLYSATE FOR PRODUCING BIOCHEMICALS OR BIOFUELS, AND DETOXIFIED WOOD-BASED HYDROLYSATE - Provided is a method for producing a saccharified solution of wood-based biomass having toxicity reduced or removed, comprising the steps of: preparing a saccharified solution in which wood-based biomass has been pretreated by hydrolysis; and reducing toxicity in the saccharified solution using an electrochemical detoxification method. The method is capable of efficiently removing the toxicity of compounds which are produced during the pretreatment process and inhibit growth of microorganisms and fermentation. In addition, the method is capable of increasing the efficiency of production by minimizing sugar loss and additional costs during the toxicity removal process. | 01-28-2016 |

20110294176 | METHOD OF EXTRACTING BUTYRIC ACID FROM A FERMENTED LIQUID AND CHEMICALLY CONVERTING BUTYRIC ACID INTO BIOFUEL - Disclosed is a method of converting butyric acid contained in a fermentation broth into biofuel. This chemical conversion method includes separating biohydrogen from gases generated in the course of production of butyric acid through fermentation of carbohydrate, extracting butyric acid from the broth using an insoluble solvent, esterifying butyric acid thus producing butylbutyrate, and hydrogenolyzing all or part of butylbutyrate, thus obtaining butanol. Thereby, biobutanol can be efficiently and economically produced, and butylbutyrate, which has oxidation stability superior to that of conventional biodiesel (fatty acid methyl ester) and is thus regarded as novel biofuel, can be produced together. | 12-01-2011 |

20140220640 | METHOD FOR MANUFACTURING DETOXIFICATED LIGNOCELLULOSIC BIOMASS HYDROLYSATE WITH DECREASED OR ELIMINATED TOXICITY AND METHOD FOR MANUFACTURING ORGANIC OR AND BIOFUEL USING THE SAME - Disclosed is a method for detoxifying a lignocellulosic biomass hydrolysate, including: preparing a hydrolysate by pretreating a lignocellulosic biomass by hydrolysis; and decreasing or removing toxicity by adding a surfactant to the hydrolysate. The detoxifying method according to the present disclosure may effectively remove toxicity of compounds derived from lignin that inhibit the growth of and fermentation by microorganisms during the pretreatment of lignocellulosic biomass. Further, production efficiency can be improved since loss of sugar can be avoided during the detoxification and additional cost can be minimized. | 08-07-2014 |
20150064761 | PROCESS OF PRODUCING BIOENERGY WITH LOW CARBON DIOXIDE EMISSIONS AND ZERO-WASTE OF BIOMASS - Disclosed herein is a bioenergy production system with reduced carbon dioxide emissions and process wastes; including a process for producing a bioalcohol and a biogas by subjecting a biomass, such as: herbaceous and woody plants, fruit pulp, freshwater and sea algae, grains, aerobic and anaerobic sludge, saccharides, polyols and carbohydrates, to a combined process of a biosaccharification/alcohol fermentation, including a biomass pretreatment process; and a process for producing a methane biogas with a reduced level of carbon dioxide and hydrogen sulfide, via an algae cultivation process with a view to purifying the carbon dioxide and hydrogen sulfide contained in the biogas; wherein, when the algae to be cultivated is microalgae, biodiesel is produced by subjecting the harvested microalgae to a biodiesel manufacturing process while recycling the glycerol and the saccharide-containing waste produced as byproducts to the biosaccharification/alcohol fermentation process, and when the algae to be cultivated is macroalgae the harvested macroalgae is recycled to the biosaccharification/alcohol fermentation process. The method of the present invention is effective in reducing carbon dioxide emissions, a representative green house gas contributing to the global warming, and also in optimizing a zero-waste bioenergy production system. | 03-05-2015 |
