Abstract

A study on deep desulfurization for ultra-clean fuels both for fuel cell applications and for IC engines was carried out. JP-8 was the jet fuel used. Comparison of the desulfurization selectivities of various sulfur compounds in the JP-8 showed that both 2,3-dimethylbenzothiophene (2,3-DMBT) and 2,3,5/6-trimethylbenzothiophene (2,3,5/6-TMBT) exhibited similar desulfurization selectivity, while 2,3,7-TMBT and 2,3,?,7-TMBT had analogous desulfurization selectivity. 2,3-DMBT and 2,3,5/6-TMBT exhibited much higher desulfurization reactivity than 2,3,7-TMBT and 2,3,?,7-TMBT. The methyl group at the 7-position of benzothiophenes might play an important role in inhibiting the interaction between sulfur atom in the sulfur compounds and the adsorbent A-2, resulting in low desulfurization selectivity of the alkyl benzothiophenes with an alkyl group at the 7-position.
