Abstract
Provided is a catalyst for preparing a syngas by reforming methane wherein a nickel-based catalyst is mixed with a metal oxide catalyst. More particularly, alumina is used as a support and a metal oxide catalyst including magnesia, nickel, vanadium, tungsten, iron, molybdenum or chromium is used to inhibit carbon deposition and maintain or improve catalytic activity.
Claims6
A catalyst for a tri-reforming reaction of methane, wherein a nickel-based catalyst represented by Chemical Formula 1 is mixed with a metal oxide catalyst represented by Chemical Formula 2:
- Ni/MgO/Al2O3 [Chemical Formula 1]
- wherein MgO is included in an amount of 5-30 parts by weight and Ni is included in an amount of 2-40 parts by weight based on 100 parts by weight of an alumina support;
- and
- X/Y [Chemical Formula 2]
- wherein X is selected from the group consisting of molybdenum, chromium and vanadium, Y is selected from the group consisting of iron, molybdenum and tungsten and a molar ratio of X and Y is 0.1-5.
A method for preparing a catalyst for a tri-reforming reaction of methane wherein a nickel-based catalyst represented by Chemical Formula 1 is mixed with a metal oxide catalyst represented by Chemical Formula 2, wherein the catalyst of Chemical Formula 1 is prepared by:
- preparing a mixture in which magnesia is supported on an alumina support;
- stirring the mixture for 1 hour, condensing at 75-85° C. and drying at 95-110° C.;
- and
- calcinating the dried product at 750-900° C. for 5-6 hours:
- Ni/MgO/Al2O3 [Chemical Formula 1]
- wherein MgO is included in an amount of 5-30 parts by weight and Ni is included in an amount of 2-40 parts by weight based on 100 parts by weight of an alumina support;
- and
- X/Y [Chemical Formula 2]
- wherein X is selected from the group consisting of molybdenum, chromium and vanadium, Y is selected from the group consisting of iron, molybdenum and tungsten and a molar ratio of X and Y is 0.1-5.
