Katalysator für Hochtemperaturdampfreformierung von Kohlenwasserstoffen.

摘要

[OBJECT] The object of this invention is to provide a catalyst which is suitable for use in high-temperature steam reforming of hydrocarbons, exhibits less carbon precipitation when used and has high activity with a long catalytic service life. [CONSTITUTION] A catalyst for the steam reforming of hydrocarbons characterized in that 0.1-2 wt.% of ruthenium is carried on a carrier which comprises 5-40 wt.% of ceria or rare earth element oxides containing ceria as the main ingredient and 60-95 wt.% of alumina, and that an atomic ratio of cerium to ruthenium (Ce/Ru) in the catalyst is in the range of from more than 10 to 200.
