STEAM REFORMING CATALYST, STEAM REFORMING METHOD USING SAME, AND STEAM REFORMING REACTION APPARATUS

摘要

This steam reforming catalyst is used for steam reforming of oxygen-containing hydrocarbons, and contains: a carrier that includes a compound oxide in which both ceria and alumina are dispersed at the nanometer scale; at least one first metallic element selected from the group consisting of the platinum group of metals, supported on the carrier; and at least one second metallic element selected from the group consisting of the alkali metals, alkaline earth metals, and rare earth elements, supported on the carrier. In so doing, coking is sufficiently unlikely to occur, even in environments devoid of oxygen gas, or under conditions of a low molar ratio (S/C) of steam to carbon; high activity is maintained even when exposed to high temperatures; and it is possible to more efficiently reform oxygen-containing hydrocarbons with steam.
