Interactions of sulfate-promoted iron oxide So{sub 4}{sup 2-} -Fe{sub 2}O{sub 3} with 1-butene and n-butane were investigated by means of infrared spectroscopy and temperature-programmed desorption/reaction coupled with mass spectrometry. By reacting with the sulfate ion, 1-butene adsorbed on SO{sub 4}{sup 2-}-Fe{sub 2}O{sub 3} promoted sulfate decomposition. In contrast, adsorbed n-butane desorbed readily upon heating above 320 K. Implications of these findings in catalysis by this material are discussed.
