Abstract

The effectiveness of carbon nanotube/TiO₂ (CNT/TiO₂) adsorbents to desulfurize model fuels containing various thiophenes was studied. The CNT/TiO₂ adsorbents were characterized by scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR). Experiments carried out in the film-shear reactor and in a batch reactor were both very effective in removing various recalcitrant thiophenes (typically >80–90 % removal), but reactions in the film-shear reactor required far smaller TiO₂ concentrations to be effective (0.01–0.1 wt/vol% vs. 1–10 % in the batch experiments). The effectiveness of the film-shear reactor is attributed to its ability to intimately mix the fuels and the CNT/TiO₂ adsorbent. The CNT/TiO₂ nanomaterial could be regenerated by heating without loss of desulfurization ability.
