Title:
CARBON DIOXIDE REFORMING CATALYST FOR HYDROCARBONS AND CARBON DIOXIDE REFORMING METHOD FOR HYDROCARBONS
Document Type and Number:
WIPO Patent Application WO/2012/115193
Kind Code:
A1
Abstract:
Provided is a carbon dioxide reforming catalyst for hydrocarbons, with which it is possible to efficiently reform carbon dioxide in hydrocarbons while suppressing the precipitation of carbon (for example by carbon dioxide reforming methane, to generate hydrogen and carbon monoxide). Also provided is a carbon dioxide reforming method for hydrocarbons, using same. The carbon dioxide reforming catalyst for hydrocarbons contains a complex oxide ABO3 having a perovskite structure (the element that constitutes the A site is Sr, and may partially contain B, Ca or Mg; the element that constitutes the B site is Ti, and may partially contain Zr), and Ni, wherein (a) the molar ratio A/B of the total quantity of elements that constitute the A site and the total quantity of elements that constitute the B site falls within the range of 0.90 ≦ A/B ≦ 1.20, and (b) the molar ratio Ni/B of the total quantities of elements that constitute the B site and Ni falls within the range 0.02 ≦ Ni/B ≦ 0.16.
