    Abstract: The invention relates to a catalytic high-pressure process for CO2 reforming of hydrocarbons, preferably methane, in the presence of iridium-containing active masses, and also a preferred active mass in which Ir is present in finely divided form on zirconium dioxide-containing support material. Preferably, the predominant fraction of the zirconium dioxide has a cubic and/or tetragonal structure and, more preferably, the zirconium dioxide is stabilized with at least one doping element. In the process according to the invention, reforming gas at a pressure which is greater than 5 bar, preferably greater than 10 bar, and more preferably greater than 20 bar, and at a temperature which is in the range from 600 to 1200°C, preferably in the range from 850 to 1100°C, and particularly preferably in the range from 850 to 950°C, is brought into contact and reacted to form synthesis gas. The process according to the invention is carried out using a reforming gas that contains only small amounts of steam, or is completely steam-free. The process is characterized in that the formation of coke on the catalyst is greatly restricted when the process is being carried out, as a result of which the process can be carried out over a long time period without in this case significant losses in activity occurring.

    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.
