ANTI-SHIFT REACTION CATALYST, AND PROCESS FOR PRODUCTION OF SYNTHETIC GAS USING SAME

摘要

There are provided a catalyst for reverse shift reaction, which has excellent durability at a high temperature, and can suppress generation of a methanation reaction and efficiently generate a reverse shift reaction to produce a synthesis gas including carbon monoxide and unreacted hydrogen with the reduced methane content, and a method for producing a synthesis gas using the catalyst for reverse shift reaction. The composition of a catalyst for reverse shift reaction which is used for generating carbon monoxide and water vapor from carbon dioxide and hydrogen is a composition such that the catalyst includes a composite oxide containing at least one alkali earth metal selected from the group consisting of Ca, Sr and Ba and at least one transition metal selected from the group consisting of Ti and Zr. A raw material gas containing carbon dioxide and hydrogen is contacted with the catalyst for reverse shift reaction under a temperature condition of 700°C or higher to carry out a reverse shift reaction.
