Abstract:
A method for autothermal reforming to produce hydrogen or a synthesis gas, comprising contacting a feedstock as a starting material and a reforming gas comprising oxygen and steam with a catalyst,wherein the catalyst comprises ruthenium supported on a zirconia carrier and an amount of ruthenium supported on the carrier is from 0.05 to 20 wt. % based on the entirety of the catalyst; a ratio of steam to the feedstock fed to the reaction system is from 0.4 to 4 in terms of the number of water molecules/the number of carbon atoms in the feedstock; and a ratio of oxygen to the feedstock fed to the reaction system is from 0.2 to 0.8 in terms of the number of oxygen molecules/the number of carbon atoms in the feedstock.
