Abstract: The present invention relates to a hexaaluminate-containing catalyst, which comprises a hexaaluminate-containing phase that includes cobalt and at least one additional element from the group La, Ba, Sr. The Co content of the hexaaluminate-containing catalyst is in the range of 2-15 mol%, preferably 3-10 mol% and further preferably in the range of 4-8 mol%, the content of the at least one additional element from the group La, Ba, Sr is in the range of 2-25 mol%, preferably 3-15 mol%, further preferably 4-10 mol% and the content of Al is in the range of 70-90 mol%. In addition to the hexaaluminate-containing phase, the catalyst can include a 0-50 wt% oxide secondary phase, the portion of oxide secondary phase preferably in the range of 3-40 wt% and further preferably in the range of 5-30 wt%. The method according to the invention for producing the catalyst is based on initially bringing a source of aluminium oxide, preferably, a boehmite, into contact with cobalt species and at least one element from the group La, Ba, Sr. The moulded and dried material is preferably calcined at a temperature greater than or equal to 800°C. The reforming method for converting hydrocarbons, preferably methane, in the presence of CO2 is characterised in that the catalyst is used at a process temperature greater than 700°C, preferably greater than 800°C and further preferably greater than 900°C, the process pressure being greater than 5 bar, preferably greater than 10 bar and further preferably greater than 15 bar.

Abstract: The invention relates to a method for producing a catalyst for the high-temperature methods (i) carbon dioxide hydration, (ii) combined high-temperature carbon dioxide, and reforming and/or (iii) reforming of compounds containing hydrocarbons and/or carbon dioxide and to the use of the catalyst according to the invention in connection with the reforming and/or hydration of hydrocarbons, preferably methane, and/or carbon dioxide. For production of the catalyst a source of aluminium, which preferably comprises a water-soluble source of precursor, is brought into contact with an yttrium-containing metal salt solution, is dried, and calcined. The metal salt solution has, in addition to the yttrium species, at least one element from the group comprising cobalt, copper, nickel, iron, and zinc.

Abstract: The present invention relates to a process for producing a catalyst for carrying out methanation reactions. The production of the catalyst is based on contacting of a hydrotaicite-comprising starting material with a fusible metal salt. The compounds brought into contact with one another are intimately mixed, thermally treated so that the metal salt fraction melts and subsequently subjected to a low-temperature calcination step and a high-temperature calcination step. The metal salt melt comprises at least one metal selected from the group consisting of K, La, Fe, Co, Ni, Cu and Ce, preferably Ni. The metal salt melt more preferably comprises/contains nickel nitrate hexahydrate. The hydrotaicite-comprising starting material is preferably hydrotaicite or a hydrotalcite-like compound as starting material, and the hydrotaicite-comprising starting material preferably comprises magnesium and aluminum as metal species. The catalyst of the invention is preferably used for carrying out methanation reactions at elevated pressures (from 10 to 50 bar) and elevated temperatures.

Abstract: A catalyst for the reforming of hydrocarbon-comprising compounds with CO2, water and/or hydrogen, a process for producing the same, and a process using the same for the reforming of the hydrocarbon-comprising compounds are provided. The production of the catalyst is based on contacting, intimately mixing and thermal treating of a hydrotalcite-comprising starting material with a fusible metal salt, which more preferably comprises nickel nitrate hexahydrate, to result in the metal salt melt. After molding and shaping, the compounds are subjected to high-temperature calcination step. In addition, the process using the catalyst for the reforming of the hydrocarbon-comprising compounds is carried out in a temperature range from 500 to 1100 °C at a pressure in the range from 2 to 70 bar. The catalyst is distinguished from the prior art by physicochemical properties.
