Resumen
The need for environmental protection has demanded the searching nontoxic
catalysts easily handled and discarded. This work deals with the use of
aluminum as a substitute of chromium, in iron- and copper-based catalysts
for the high temperature shift reaction. Catalysts were prepared in the
commercial form (hematite) and was evaluated in more severe operational
conditions than the usual industrial one (e.g. steam to carbon ratios, R,
lower than 0.6). It was found that aluminum can replace chromium in these
catalysts leading to better catalytic properties as compared to chromium.
The catalyst has the advantage of being non toxic and can work in low
amounts of steam.
