Effect of preparation method on structural characteristics and propane steam …

Abstract. Propane steam reforming was studied over Ni–Al2O3 catalysts that were prepared by a conventional impregnation (IM) method and a one-step sol–gel (SG) technique. Both Ni–Al2O3 catalysts showed similar initial activity. However, IM-Ni–Al2O3 deactivated severely with time-on-stream of propane steam reforming. The catalyst prepared using a SG technique demonstrated stable cata…
