摘要

A modified ⊖-Al2O3-supported nickel reforming catalyst and its use for producing synthesis gas from natural gas, more specifically to a nickel reforming catalyst expressed by the following formula 1, having improved coke resistance, high-temperature catalysis stability and catalytic activity, which is prepared by coating nickel or mixture of nickel and cocatalyst (M1-M2-Ni) on a Al2O3 support modified with metal (M3-M4-ZrO2/⊖-Al2O3), and its use for producing synthesis gas from natural gas through steam reforming, oxygen reforming or steam-oxygen reforming,; PTEXTPDATM/PDATHILSBPDAT1/PDAT/SB/HILPDAT-M/PDATHILSBPDAT2/PDAT/SB/HILPDAT-Ni/M/PDATHILSBPDAT3/PDAT/SB/HILPDAT-M/PDATHILSBPDAT4/PDAT/SB/HILPDAT-ZrO/PDATHILSBPDAT2/PDAT/SB/HILPDAT/⊖-Al/PDATHILSBPDAT2/PDAT/SB/HILPDATO/PDATHILSBPDAT3/PDAT/SB/HILPDAT  (1) /PDAT/PTEXT ;wherein M1 is an alkali metal; each of M2 and M3 is an alkaline earth metal; and M4 is a IIIB element or a lanthanide.
