Evaluation of a Catalyst Used in the Production of Fuel Cell Hydrogen with CGT-7100

Introduction

Steam reforming is a method used to produce hydrogen gas needed for fuel cells, a green energy technology that has attracted attention in recent years. Steam reforming introduces a high temperature catalyst to a mixture of steam and raw materials such as methane or ethanol to produce hydrogen gas. Evaluation of the catalyst used during steam reforming involves an assessment of catalytic performance and how catalyst degradation is affected by different reaction temperatures, and is achieved by monitoring changes in the concentration of product components, such as CO and CO₂. The CGT-7100 comes with the ability to detect up to two components out of CO, CO₂, and CH₄, and has built-in sample pretreatment units, which allows for direct and real-time measurement of sample gases without the need for connection of separate pretreatment systems. This article describes an example evaluation of a catalyst by CO and CO₂ measurement.
