High surface area alumina powder was impregnated with the nanoparticle solution. After drying and calcination, the catalyst powder was deposited in microchannels by means of a washcoating process and after repeated drying and calcination tested for steam reforming of propane. All catalysts showed full conversion at the reaction conditions applied (T = 750 °C, S/C = 4, WHSV = 120 Nl/(h*gcat)) including during mid-term tests of 140 h uninterrupted testing.enrhodiumnanoparticlessteam reformingpropanemicrochannels540journal article
