A POROUS PREFORM (CARRIER) IS SOAKED IN AN IMPREGNATING SOLUTION, WHICH CONTAINS BOTH OF A CATALYTIC-ACTIVITY CONSTITUENT, E.G. NI AND/OR CO, AND A CARRIER-FORMING CONSTITUENT, E.G. MG, AL, ZR, TI AND/OR CA, SO AS TO SIMULTANEOUSLY INFILTRATE THE CATALYTIC-ACTIVITY AND CARRIER-FORMING CONSTITUENTS INTO THE POROUS PREFORM. THE IMPREGNATED PREFORM IS DRIED, CALCINED AT A TEMPERATURE OF 700°C OR HIGHER AND THEN ACTIVATED AT A TEMPERATURE OF 500°C OR HIGHER, WHEREBY FINE CATALYTIC-ACTIVITY PARTICLES ARE DISTRIBUTED ON A SURFACE OF THE POROUS CARRIER WITH HIGH DISPERSION. DUE TO FINELY-DISTRIBUTED CATALYTIC-ACTIVITY PARTICLES, THE SURFACE OF THE CATALYST IS PREVENTED FROM DEPOSITION OF CARBONACEOUS MATTERS DURING REFORMATION OF HYDROCARBON AND HELD IN AN ACTIVE STATE OVER A LONG TERM. |
