WATER GAS SHIFT CATALYST AND ITS SYNTHETIC METHOD WHICH IS HIGHLY DISPERSED COPPER BY BOROHYDRIDE TREATMENT

PURPOSE: A water gas shift reaction catalysis composition, a slurry composition including the same, a water gas shift reaction catalyst using the same and a manufacturing method thereof are provided to maximize an area of active surface in which copper occupies, to increase reaction activity of a catalyst while maintaining a physical characteristic of a catalyst through this by finely particlizing and highly diffusing copper of an active material with low cost to a supporter using a liquid phase reduction method. CONSTITUTION: A water gas shift reaction catalysis composition includes an active component, a reducer including an MBH4 (M is alkali metal), a carrier, a supporter and an inorganic binder. The active component contains more than one copper precursor and metal oxide selected from a group consisting of Cu(CH3COO)2 and Cu(NO3)2. The carrier contains more than one selected from a group consisting of hydrochloric acid, acetic acid, nitric acid and nitrate. The active component is included by 10-70 parts by weight with respect to a catalysis composition 100 parts by weight. The alkali metal M is Na or Li. The reducer is included by 0.001-0.1 parts by weight with respect to a catalysis composition 100 parts by weight. The carrier is included by 0.0001-0.01 parts by weight with respect to a catalysis composition 100 parts by weight. The supporter is more than one selected from a group consisting of alumina, silicon dioxide, zeolite and hydrotalcite. The inorganic binder is more than one selected from a group consisting of a clay group and a ceramic group.
