“…The most prevalent and industrially relevant sulfur removal technology is hydro desulfurization (HDS). Alternative sulfur removal processes such as catalytic oxidation (Mei et al 2003;Wang et al 2007aWang et al , 2007b, biological removal (Grossman et al 1999;Klein 1999;Ma et al 2006;McFarland et al 1998;Zakharyants et al 2005) and membrane separation are being pursued for when HDS is inefficient or cost-prohibitive. Another emerging alternative is adsorptive removal of sulfur in liquid feeds.…”

Sulfur capacity of SiO 2 , TiO 2 and γ -Al 2 O 3 structures was investigated. Thermal treatment of TiO 2 and γ -Al 2 O 3 in air increased their respective sulfur capacity by 67 and 43%. Sulfur capacity was associated with surface acidity and the improvement attributed to the formation of bronsted acid sites. Addition of 4wt% transition metals further enhanced the sulfur capacity of TiO 2 with Ag indicating the highest increase. Comparison of sulfur capacity of Ag/TiO 2 with other adsorbents was made using JP5 fuel with sulfur concentration of 1172 ppmw. Ag/TiO 2 adsorbent demonstrated a saturation sulfur capacity of 8.20 mg/g. A significant loss in sulfur capacity was observed between real and model fuel compositions. Various factors resulting in this loss was investigated such as the effect of additives, competitive adsorption and the structure of sulfur heterocycles.

“…When the ratios of CeO 2 -NiAlLDHs and CNTs were 10:1, 20:1 and 30:1, the results showed that the peak currents of aqueous sulfur dioxide and hydrogen sulfide were larger at 20:1. As a comparison, Table 5 summarizes the electrochemical desulfurization efficiency using different electrodes [43][44][45][46]; we can find that the desulfurization efficiency at CeO 2 -NiAl-LDHs/AC is comparable with their work.…”

“…Comprehensive above research, the plastic deformation and elastic deformation are created simultaneously after the guide pads burnished, that lead to the enlargement of the machined hole. With the different workpiece materials, the plastic deformation part of the hole wall is differentand proportional to feed rate f. The deep hole bore diameter enlargement magnitude ∆D [7] caused by guide pads brunished can be represented astheequation (1):…”

Abstract. Deep hole machining accuracy plays a crucial role in product's quality. The results of an investigation into the machining accuracy of deep drilling holes which highlights problems of bore diameter enlargement magnitude assessment are presented in this paper. Through the study of BTA deep drilling tool properties and mechanism, as well as the formation rule of deep hole surface, clarified the burnishing mechanism of guide pad in deep hole drilling, and obtained the directly relationship between surface formation rule and the guide pad. After drilling experimentrevealed the effect of guide pad on bore diameter enlargement magnitude.
