Abstract:
The present invention relates to a system for manufacturing a hydrocarbon compound by using Fischer-Tropsch synthesis. A catalyst reduction reactor of the present invention in the system for manufacturing the hydrocarbon compound by using the Fischer-Tropsch synthesis comprises a mixer into which an iron-based catalyst is charged, a first synthetic gas is injected for reducing the iron-based catalyst, and into which a second synthetic gas is injected so as to be mixed with the reduced iron-based catalyst. As a result, a catalyst is reduced (activated) in a separate reactor and then introduced into the Fischer-Tropsch reactor thereby facilitating introduction of an additional catalyst when manufacturing the hydrocarbon compound using the Fischer-Tropsch synthesis, and reducing the time required for manufacturing.
Abstract:
PURPOSE: An apparatus for simultaneous production of synthetic oil and electricity is provided to synthesize synthetic oil by supplying synthetic gas to a Fischer-Tropsch synthesis reactor unit. CONSTITUTION: A steam methane modifier(1) generates a synthetic gas with a H2/CO ratio of 3:1 or more by modifying supplied natural gas. A first and a second heat exchanger(21,22) are installed in a heat exchanger supply pipe(2), to supply high temperature synthetic gas to a pressure-changing absorption separator(3). The pressure-changing absorption separator separates the synthetic gas into a synthetic gas with H2/CO ratio of 2:1, and high purity hydrogen, and supplies the same to a synthetic gas supply pipe and high purity hydrogen supply pipe, respectively. A Fischer-Tropsch synthesis reactor unit generates electricity by using the high purity hydrogen. A methane heat exchange supply pipe(6) has a third heat exchanger(61) to increase the temperature of methane, and supplies the methane.

Abstract:
PURPOSE: A highly loadable and dispersive metal-oxide/carbon nano catalyst carrier and a production method thereof are provided to easily obtain catalysts in which metal-oxide particles are well dispersed along with carbon residues by removing excessive carbon substances which exists in a porous carbon molding frame. CONSTITUTION: A production method of highly loadable and dispersive metal-oxide/carbon nano catalyst carrier comprises the following steps; a mixing step which mixes metal-salt hydrate with a carbon molding frame in a porous structure; an impregnation step which impregnates the metal-salt hydrate in the carbon molding frame after melting and impregnating around the melting point of the metal-salt hydrate; a drying step which dehydrates the obtained mixed powder; and a removal step which forms metal oxide particles by sintering the carbon molding frame, in which the metal-salt hydrate is loaded, and removes carbons from the carbon molding frame leaving the partial amount of carbon. A sintering temperature above is ranged from 200 to 700 deg. C, and a sintering period is ranged from 30 to 48 hours.
