A catalytic exhaust-gas reformer is a largely passive reactor; which has to be capable of operating effectively at flow rates and inlet temperatures determined by the internal combustion engine. In this study; we examine the limited number of design parameters that can allow us to maximise the engine-reformer system efficiency while improving vehicle emissions. In principle; this balance requires that the endothermic hydrogen-generating reactions (steam reforming and dry reforming) are promoted at the expense of the exothermic reactions (oxidation; water-gas shift and methanation). In practice; an oxidation function is necessary for generating heat to drive the endothermic reactions; particularly at low exhaust gas temperatures. Water-gas shift and methanation respond to changes in size and aspect ratio of the reformer; but the ideal configuration for suppressing these CO-consuming reactions does not favour the efficient endothermic reactions at all operating conditions. Our results imply that the optimum exhaust-gas reformer cannot be achieved through reactor engineering alone; but will require further catalyst design. © 2006 Elsevier B.V. All rights reserved;
