Activity of steam reforming catalysts: Role and assessment

Abstract The characteristics of the tubular steam reforming process and the role of the catalyst are outlined. Testing of catalytic properties is discussed with special emphasis on difficulties of scaling down from an industrial scale to different types of laboratory reactors. A recirculation-type laboratory reactor was found to be well suited for studies on industrial-size catalyst particles. For the demonstration of new and critical operating conditions, it is necessary to use a pilot plant. A full-size monotube unit for this purpose is described together with data for operation at a low steam-to-carbon ratio.
