Abstract

The active species over a sulfated transition metal oxide catalyst for propane dehydrogenation were evaluated. The unsulfated catalyst showed a high conversion for the dehydrogenation of propane, with significantly low selectivity to the desired product of propylene, on the other hand, the sulfated catalyst displayed a high selectivity to propylene, though the conversion was slightly decreased. The sulfation treatment was especially effective for the Co and Fe catalysts. The sulfate species were reduced to the active species of the sulfide ion in the reaction atmosphere, which increased a selectivity to propylene.
