Catalyst for manufacturing synthetic gas through steam-carbon dioxide reforming, and method for manufacturing synthetic gas by using same

摘要

The present invention relates to a catalyst for manufacturing a synthetic gas from a natural gas by using carbon dioxide, and more specifically, to a catalyst useful for manufacturing a synthetic gas by means of steam-carbon dioxide reforming. The catalyst according to the present invention is manufactured by a method comprising the steps of: 1) manufacturing a zirconia and alumina support coated with cerium by using dry mixing; 2) preparing nickel and magnesium oxide powders; and 3) mixing and firing a powder of the support in step 1) and powders of metals in step 2). The ratio of hydrogen to carbon monoxide in the synthetic gas, which is manufactured by using the catalyst according to the present invention, can be controlled to 2.0±0.2, thereby easily providing the synthetic gas which is efficient for producing synthetic petrochemical products (such as wax, naphtha, and diesel).
