  • Patent number: 9850509
    Abstract: Provided are an oleaginous microorganism disruption process using a supersonic disperser and a method for producing bio-oil using the same. The method for producing bio-oil according to the present invention induces a cell disruption of oleaginous microorganisms without a separate drying process, thereby providing a method for continuously producing bio-oil in an economical and simple manner. In addition, the method of the present invention induces a cell disruption of oleaginous microorganisms without a heating process, thereby producing bio-oil without a change in physical properties due to the heat.

  • Patent number: 9187767
    Abstract: The present invention relates to a method for producing hydrocarbons from biomass or organic waste. The present invention provides: a method for effectively producing diverse hydrocarbons by using a raw material comprising mixed organic acids that can be obtained by anaerobic fermentation which is a fermentation process in biogasification technology; and a method for producing diverse products such as fuel, lube base oil and aromatics by using a raw material comprising mixed organic acids.

  • Patent number: 8728782
    Abstract: 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.

  • Publication number: 20110300596
    Abstract: The present invention relates to a preparation method for alcohol by reacting carboxylic acid, alcohol, and hydrogen using hydrogenation catalysts. More specifically, the invention relates to a method for preparing alcohol by performing esterification and hydrocracking in a one-step process using hydrogenation catalysts instead of a two-step process. According to the invention, alcohol is prepared from carboxylic acid through esterification and hydrogenation in a one-step process using hydrogenation catalysts. Therefore, production costs and by-product treatment costs can be reduced in comparison to a two-step process. In addition, the invention is effective and economical since it can produce alcohol at relatively high yield by a simple process. Further, the invention allows high yield at relatively lower pressure when compared to alcohol production from carboxylic acid through hydrogenation without esterification and solves the problems of leaching by catalysts.
