Abstract
A soot resistant and efficient diesel fuel reformer for a diesel exhaust aftertreatment system has serially arranged first and second catalyst supports. The first support is nearer the inlet and has a monolith structure that is uniform in the direction of flow. The second support has a modified monolith structure that is non-uniform in the direction of flow. Preferably, the first support has straight channels. Preferably, the second support has internal leading edges spaced periodically through its length to break up the flow. The first support has a catalyst coating comprising at least an oxidation catalyst. The second support has a catalyst coating comprising at least a steam reforming catalyst.
