Abstract: PURPOSE: A micro-macro channel reactor is provided to improve the performance per volume of the reactor and to improve the distribution, the flux increase of reactants and the efficiency of the reactor. CONSTITUTION: A micro-macro channel reactor includes an upper end plate(20), a lower end plate(60), a heat exchanging plate(30), a catalyst plate(40), and a supporting plate(50). The catalyst plate is stacked to the thermal exchanged plate. The catalyst plate includes a catalyst part(41). While reactants pass through the catalyst part, the catalytic reaction of the reactants is generated. The supporting plate is stacked to the catalyst plate and provides a flow path(52) through which the reactants pass. The heat exchanging plate, the catalyst plate, and the supporting plate are stacked between the upper end plate and the lower end plate.

Abstract: PURPOSE: A catalyst for a fischer-tropsch reaction using a mesoporous silica structure is provided to efficiently generate an intermediate distilled product in a liquid hydrocarbon range by manufacturing a stable catalyst support to the fischer-tropsch reaction. CONSTITUTION: An emulsion is generated by adding a surfactant to an organic solvent and an acidic aqueous solution. Silicon alkoxide is added to the emulsion to synthesize silica. The silica is aged and filtered. The filtered silica is dried and sintered to obtain mesoporous silica. A reactive metal for a fischer-tropsch catalyst is introduced to the mesoporous silica to obtain a fischer-tropsch catalyst. The reactive metal is the mixed metal of two or more selected from a group including cobalt, iron, ruthenium, nickel, palladium, platinum, and rhodium. The acidic aqueous solution is the aqueous solution of one or more selected from a group including hydrochloric acid, nitric acid, sulfuric acid, acetic acid, carbonic acid, and acetic acid.
