Comparative studies of the hydrodesulfurization (HDS) of thiophene, 2,3-dihydrothiophene, 2,5-dihydrothiophene and tetrahydrothiophene were performed using Mo/{gamma}-Al{sub 2}O{sub 3} and Re/{gamma}-Al{sub 2}O{sub 3} catalysts. Reaction pathways for interconverion of the organosulfur compounds were shown to exist. Both dihydrothiophene compounds were high reactive and formed significant amounts of 1,3-butadiene at 300{degree}C over Re catalysts. The dihydrothiophenes are proposed to be possible reaction intermediates for thiophene HDS.
