“…3A), except in the mixtures containing the FA conditioner, for which the DTG showed also a second peak with a shoulder (Fig. 3B), as expected (mainly due to the presence of BC; Soares et al, 1997). On the other hand, the AE and AN + AE mixtures, but not the AN mixtures, displayed an endothermic peak with a noticeable weight loss at about 600-700°C ( Fig.…”

“…Their characteristics are summarized in Table 1. Samples with no pore former exhibited mass gain due to oxidation of SiC particles [19]. Burning of carbon was responsible for loss in mass in samples containing pore former [20]; % mass loss and bulk porosity increased with increase in fractional volume of the pore former.…”

“…Figure 7 presents the TPO/TG-DTG plots of the spent NiW/Al, NiW/AT2 and NiW/AT10 catalysts. The weight loss in the TG profiles, corresponding to the most intense DTG peak centred at 460°C can be assigned to lose of the sulfur atoms from oxo-sulfide species whereas the second weight loss (DTG peak centred at *700°C) is characteristic of coke oxidation [42]. Table 5 compiles the weight loss corresponding to the decomposition of metal sulfide species and oxidation of coke.…”

This work showed that the use of Al 2 O 3 -TiO 2 as carriers has a positive effect on the activity of supported NiW catalysts in the hydrodesulfurization of dibenzothiophene and 4,6-dimethyldibenzothiophene carried out in a batch reactor at 320°C and total H 2 pressure of 5.5 MPa. Two Al 2 O 3 -TiO 2 mixed oxides with Al/Ti atomic ratios of 10 and 2 were synthesized by sol-gel method together with the pure Al 2 O 3 synthesized as reference support. For NiW/ Al 2 O 3 -TiO 2 and NiW/Al 2 O 3 catalysts, a metal load of 17 and 5.5 wt% of W and Ni were considered respectively. It was found that both Al 2 O 3 -TiO 2 -supported catalysts exhibited higher activity than alumina-supported one. The catalyst with a largest TiO 2 content (NiW/AT2) demonstrated to be 23 % more active with respect to NiW/Al 2 O 3 . Solids were characterized by temperature-programmed reduction (TPR), high resolution transmission electronic microscopy and X-ray photoelectronic spectroscopy (XPS) techniques. A decrease in support-metal interaction (from TPR) was observed when Ti content increased, which could lead to a higher amount of NiWS phase (from XPS). Besides, a slight increase in the slabs length in WS 2 was observed for titania-containing catalyst with respect to NiW/Al 2 O 3 , indicating that the dispersion can still be optimized. The atomic ratio Al/Ti = 2 of the NiW/Al 2 O 3 -TiO 2 catalyst proved to be a potential substitute for current catalysts for sulfur reduction in ultra-clean diesel.
