Abstract
A catalyst for reforming hydrocarbons may include a catalytically active amount of nickel or nickel oxide dispersed on a metal oxide support. The metal oxide support may be of a single-metal oxide of a first metal or a complex-metal oxide of the first metal and a second metal. A co-catalyst of magnesium oxide (MgO) may anchor the nickel or nickel oxide onto the metal oxide support.
Claims26

- wherein the catalyst is represented by the following Chemical Formula 1,
- NiaMgb[AxB(1-x)]cOd [Chemical Formula 1]
- wherein
- A is the first metal and selected from Ce, Si, La, and Al,
- B is the second metal and selected from Zr and Y,
- a, b, c, d, and x are real numbers, with a:b ranging from about 1:0.5 to about 1:2.3, a:c ranging from about 1:10 to about 1:1, and 0<x≦1.
A method of manufacturing a catalyst for reforming hydrocarbons that includes a catalytically active amount of nickel or nickel oxide dispersed on a metal oxide support, the metal oxide support being a single-metal oxide of a first metal or a complex-metal oxide of the first metal and a second metal, and a co-catalyst of magnesium oxide (MgO) anchoring the nickel or the nickel oxide onto the metal oxide support, the method comprising:
- a) dissolving a water-soluble salt of the first metal, a water-soluble salt of the nickel, a water-soluble salt of magnesium, and, optionally, a water-soluble salt of the second metal in water to provide an aqueous solution;
- b) heating the aqueous solution to obtain a heated aqueous solution;
- c) adding a precipitating agent to the heated aqueous solution and aging to form a precipitate;
- d) filtering the precipitate and washing with water at least once to obtain a filtered precipitate;
- e) drying the filtered precipitate to obtain a dried precipitate;
- and
- f) calcinating the dried precipitate,
- wherein the catalyst is represented by the following Chemical Formula 1:
