STEAM MODIFICATION CATALYST HAVING Ru ON CARRIER CONTAINING 12SrO 7Al2O3 COMPOUND HAVING MAYENITE STRUCTURE, PREFERABLY CARRIER MAINLY CONTAINING THE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a steam modification catalyst of hydrocarbon containing heavy hydrocarbon and/or aromatic hydrocarbon, for example hydrocarbon having less carbon deposition and excellent activity and life even when used kerosene as a raw material for manufacturing hydrogen by steam modification.SOLUTION: There is provided a steam modification catalyst of hydrocarbon containing a carrier containing 12SrO 7AlOcompound having a cage structure with positive charge and a Mayenite structure including oxygen anion radical in the cage and Ru carried on the carrier. There is provided a steam modification catalyst of hydrocarbon which is a mixed crystal of 12SrO 7AlOand 3SrO AlOor/and SrCOwith the content of the 12SrO 7AlOof 50 wt.% based on total weight of the carrier, preferably 80 wt.% or more and Ru carried amount of 0.1 to 5.0 wt.%.SELECTED DRAWING: Figure 1
