20110117456 | ZINC AIR FUEL CELL WITH ENHANCED CELL PERFORMANCE - Provided is a zinc air fuel cell with enhanced cell performance, more particularly a zinc air fuel cell which includes a separator-electrode assembly including a perforated metal plate as a cathode current collector, a catalyst-coated carbon paper, a separator, a perforated metal plate as an anode current collector, and a tilted nonconductive support. Furthermore, a metal plate may be placed on the tilted nonconductive support and connected to the anode current collector in the separator-electrode assembly to enlarge the active area of the anode current collector. For the zinc air fuel cell according to the present invention, a manufacturing cost may be reduced by using a mixture of MnO | 05-19-2011 |
20110196139 | PREPARATION METHOD FOR CELLULOSE PHOSPHITE COMPOUNDS - Provided is a method for preparing a cellulose phosphite compound, more particularly a method for preparing a cellulose phosphite compound whereby cellulose is phosphorylated using an ionic liquid comprising an amine-based cation and a phosphite-based anion. | 08-11-2011 |
20120083642 | IONIC LIQUIDS, THE METHOD FOR PREPARING THE SAME AND METHOD FOR REMOVING ACETYLENES FROM OLEFIN MIXTURES USING THE IONIC LIQUIDS - There are provided an ionic liquid having ether group(s) in which a copper(I) compound is included, a method for preparing the same, and a method for removing traces amounts of acetylene-based hydrocarbon compounds included in olefin by absorption or extraction using the same. When the disclosed solution is used, oxidation of Cu(I) to Cu(II) is prevented since CuX is stabilized by the ionic liquid. Thus, selective removal efficiency of acetylenic compounds is improved greatly while the removal performance is retained for a long period of time. Further, since the solution according to the present disclosure is applicable as an extractant as well as an absorbent, the associated operation is simple and apparatus cost can be decreased. | 04-05-2012 |

20140296523 | Ionic Liquids, The Method For Preparing The Same And Method For Removing Acetylenes From Olefin Mixtures Using The Ionic Liquids - There are provided an ionic liquid having ether group(s) in which a copper(I) compound is included, a method for preparing the same, and a method for removing traces amounts of acetylene-based hydrocarbon compounds included in olefin by absorption or extraction using the same. When the disclosed solution is used, oxidation of Cu(I) to Cu(II) is prevented since CuX is stabilized by the ionic liquid. Thus, selective removal efficiency of acetylenic compounds is improved greatly while the removal performance is retained for a long period of time. Further, since the solution according to the present disclosure is applicable as an extractant as well as an absorbent, the associated operation is simple and apparatus cost can be decreased. | 10-02-2014 |
20150045589 | CARBON-BASED PALLADIUM CATALYST OBTAINED BY USING IONIC LIQUID, METHOD FOR PREPARING THE SAME AND HYDROGENATION OF HYDROFLUOROCARBON USING THE SAME - Provided is a palladium on carbon (Pd/C) catalyst obtained by using an ionic liquid, a method for preparing the same, and a method for hydrogenation of hydrofluorocarbon using the same. More particularly, palladium particles are supported on carbon particles by using an ionic liquid, and the resultant Pd/C catalyst is used for hydrogenation of hydrofluorocarbon. The catalyst includes palladium particles having a smaller particle size and a more uniform shape as compared to the existing Pd/C catalysts, and thus shows high catalytic activity. | 02-12-2015 |
