YTTRIUM-CONTAINING CATALYST FOR HIGH-TEMPERATURE CARBON DIOXIDE HYDRATION, COMBINED HIGH-TEMPERATURE CARBON DIOXIDE HYDRATION, AND REFORMING AND/OR REFORMING, AND A METHOD FOR HIGH-TEMPERATURE CARBON DIOXIDE HYDRATION, COMBINED HIGH-TEMPERATURE CARBON DIOXIDE HYDRATION AND REFORMING AND/OR REFORMING

摘要

The invention relates to a process for producing a catalyst for the high-temperature processes (i) carbon dioxide hydrogenation, (ii) combined high-temperature carbon dioxide hydrogenation and reforming and/or (iii) reforming of hydrocarbon-comprising compounds and/or carbon dioxide and the use of the catalyst of the invention in the reforming and/or hydrogenation of hydrocarbons, preferably methane, and/or of carbon dioxide. To produce the catalyst, an aluminum source, which preferably comprises a water-soluble precursor source, is brought into contact with an yttrium-comprising metal salt solution, dried and calcined. The metal salt solution comprises, in addition to the yttrium species, at least one element from the group consisting of cobalt, copper, nickel, iron and zinc.
