Abstract

Differently supported Ni-based catalysts, with variable metal loading, have been synthesized by means of an innovative prepn. procedure. This technique, named Flame Spray Pyrolysis, allows the continuous one-step prodn. of nanosized particles, characterized by high thermal stability due to a flash calcination for a few milliseconds into a flame. The morphol. and structural features of the as prepd. supports and of activated catalysts are here summarized, together with catalyst performance for the steam reforming of bioethanol at 750°C, atm. pressure. Alumina, chosen for comparison with com. catalysts for this application, did not show a suitable support due to its high surface acidity, which leads to faster coking with respect to other supports. Increasing Ni loading allowed to increase H2 productivity and the best results were achieved with the sample 15 wt.% Ni/La2O3
