Abstract
Methane steam reforming (MSR) technology is the most widely used route for conversion of CH4 into H2. The conventional process usually operates in a high temperature range of 973–1173 K due to the highly endothermic nature of the reforming reaction. The need to increase energy efficiency of the process requires the development of processes operating at low temperature, as well as highly active and coke resistant catalysts.
An active catalyst which can provide high reforming reaction rates at low temperature is required. Authors review the latest developments on catalysts for methane steam reforming at low reaction temperature. They present three major groups of materials: nickel-based, noble metal-based and bimetallic catalysts. They describe the strategies proposed by several authors to enhance the performance of catalysts.
