Abstract
High surface area, nanocrystalline mixed metal oxides Ti-Ce-Al-Ag-O with different Ag loadings were prepared by co-precipitation method. Liquid-phase adsorption of jet fuel JP-5 with 1040 ppm sulfur was conducted over Ti-Ce-O, Ti-Ce-Al-O, and Ti-Ce-Al-Ag-O adsorbents at room temperature under atmospheric pressure. Ti-Ce-Al-Ag-O exhibited better adsorption desulfurization performance. Ti-Ce-Al-Ag-O has higher sulfur adsorptive capacity than that of Ti-Ce-O, and Ti-Ce-Al-O. The sulfur adsorptive capacity of JP-5 jet fuel over Ti-Ce-Al-Ag-O was increased 114% compared to that of Ti-Ce-Al-O in a batch system. The regeneration stability of Ti-Ce-Al-Ag-O was investigated and the adsorbents were characterized by XRD, BET and SEM methods. Adding silver to Ti-Ce-Al-O promotes the dispersion of metal oxides and improves the sulfur adsorption capacity. Ti-Ce-Al-Ag-O has better oxidatively regeneration stability and can be regenerated in air. The characterization results further indicate that the structure and morphology of Ti-Ce-Al-Ag-O can be retained after oxidative regeneration in air. Mixed metal oxide Ti-Ce-Al-Ag-O is a promising adsorbent for sulfur removal from jet fuels.
