  • 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.

  • Patent number: 8206576
    Abstract: The present invention relates to a nickel-based catalyst using hydrotalcite-like precursor and a steam reforming reaction by using the catalyst, and particularly to a nickel-based catalyst prepared by dispersing nickel uniformly onto the inner part and the surface of the support through a substitution between the magnesium and the active nickel metal and optimizing the molar ratios of nickel, magnesium and aluminum in order to utilize nickel as an active metal and a hydrotalcite-like precursor consisting of aluminum and magnesium, which shows an increased specific surface area of the catalyst and surface area of the active nickel, and thus enables the production of hydrogen-rich gas in high yield during the steam reforming reaction of LPG with superior maintenance of catalytic activity for a long period of time due to the inhibition of carbon deposition.

  • 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.
