20090074633 | Microtubular honeycomb carbon material obtained by heat-treating cellulose fiber, production method of thereof, microtubular reactor module comprising the microtubular honeycomb carbon material and method for producing the microtubular reactor module - Disclosed herein are a microtubular honeycomb carbon material obtained by heat-treating cellulose fiber, a production method thereof, a microtubular reactor module fabricated using the microtubular honeycomb carbon, a method for producing the microtubular reactor module, and a microcatalytic reactor system comprising the microtubular reactor module. A carbon material having a new structure is produced by heat-treating cellulose fiber, and a catalytic reactor system having a new structure is constructed by coating the surface of the carbon material with a metal catalyst. Cellulose carbide, used as the reactor material, is very simple to produce. Because it has a micro honeycomb structure having a large number of microchannels and a large number of mesopores, it can be loaded with a large amount of a catalyst compared to the prior material having the same area, and thus it is useful as a catalyst support, and the reaction efficiency can be maximized. Also, the microcatalytic reactor system can be used in applications including very small steam reformer systems that use biomass fuel such as ethanol, fuel cell reactor systems, VOC and low-concentration-hydrogen treatment systems operable below 200 □, micro heat exchangers, and natural gas reformer systems. Thus, the invention is a useful, industrially applicable invention. | 03-19-2009 |

20110212293 | ECO-FRIENDLY INCOMBUSTIBLE BIOCOMPOSITE AND METHOD FOR PREPARING THE SAME - Disclosed is an eco-friendly incombustible biocomposite including: a) a polymer matrix comprising a natural fiber; and b) a ceramic sheet laminated integrally with the polymer matrix. The biocomposite is eco-friendly since the natural fiber is used as a reinforcement material and is incombustible since it is laminated integrally with the ceramic sheet. Further, it has superior storage modulus, dimensional stability and flexural properties and lightweightness, and is processable into various structures. Thus, it is very useful for automotive or building indoor/outdoor materials. | 09-01-2011 |
20120277091 | Method of Preparing Catalyst Using Alkali Metal or Alkaline Earth Metal in Natural Cellulose Fibers as Co-Catalyst and Dispersant - A method of preparing a catalyst using an alkali metal or an alkaline earth metal in natural cellulose fibers as a co-catalyst and a dispersant.
