  • Patent number: 8513479
    Abstract: The present invention relates to a zinc ferrite catalyst, a method of producing the same, and a method of preparing 1,3-butadiene using the same. Specifically, the present invention relates to a zinc ferrite catalyst which is produced in a pH-adjusted solution using a coprecipitation method, a method of producing the same, and a method of preparing 1,3-butadiene using the same, in which the 1,3-butadiene can be prepared directly using a C4 mixture including n-butene and n-butane through an oxidative dehydrogenation reaction. The present invention is advantageous in that 1,3-butadiene can be obtained at a high yield directly using a C4 fraction without performing an additional process for separating n-butene, as a reactant, from a C4 fraction containing impurities.

  • Patent number: 8367885
    Abstract: This invention relates to a method of preparing a multicomponent bismuth molybdate catalyst by changing the pH of a coprecipitation solution upon coprecipitation and a method of preparing 1,3-butadiene using the catalyst. The multicomponent bismuth molybdate catalyst, coprecipitated using a solution having an adjusted pH, the preparation method thereof, and the method of preparing 1,3-butadiene through oxidative dehydrogenation using a C4 mixture including n-butene and n-butane as a reactant are provided. The C4 raffinate, containing many impurities, is directly used as a reactant without an additional process for separating n-butane or extracting n-butene, thus obtaining 1,3-butadiene at high yield. The activity of the multicomponent bismuth molybdate catalyst can be simply increased through precise pH adjustment upon coprecipitation, which is not disclosed in the conventional techniques.

  • 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.
