An apparatus and process are provided for electricity production and high-efficiency trapping of carbon dioxide, using carbon dioxide within combustion exhaust gas and converging technologies associated with a carbon dioxide absorption tower and a generating device using ions which uses a difference in concentration of salinity between seawater and freshwater. It is expected that enhanced electrical energy production efficiency, an effect of reducing costs for the operation of a carbon dioxide trapping process, and electricity production from carbon dioxide, which is a greenhouse gas, can be simultaneously achieved by increasing the difference in concentration using an absorbent for absorbing carbon dioxide.

Carbon dioxide trapping device and method capable of producing electricity

A carbon dioxide capturing apparatus and process uses a self-generating power means that uses carbon dioxide in combustion exhaust gas through the convergence of a carbon dioxide absorption tower. The capturing apparatus and process also relies on ionic generator associated technology using a concentration difference between seawater and freshwater. The capturing apparatus and process result in increased production efficiency for electric energy and reduced costs for a carbon dioxide capturing process by increasing a concentration difference using an absorbent liquid for absorbing carbon dioxide and, at the same time, electricity is obtained through carbon dioxide which is a greenhouse gas.

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&#x25a1;, micro heat exchangers, and natural gas reformer systems. Thus, the invention is a useful, industrially applicable invention.
