Hydroconversion of Heptane over Pt/Al-Pillared Montmorillonites and Saponites. A Comparative Study

Pillared montmorillontes from unusual antiperspirant aqueous solutions: Characterization and catalytic tests

“…This fact could be related to acidic character of the catalyst at 350°C. Previous studies reported that I/C ratios were higher than 1 and lower than 3 for other pillared clays [45]. These data indicated that the pillared clays could be a potential candidate for this type of reaction.…”

“…This might be related to the strength of protonic sites in zeolites and the shape of the pores [43,44]. Compared to other pillared clay minerals prepared from different sources, the isomer selectivity was in the same range of 50% [45] (see Fig. 11).…”

Pd–Al pillared clays as catalysts for the hydrodechlorination of 4-chlorophenol in aqueous phase

“…Pd was introduced in the Al-PILC by two different methods: wet impregnation, a method reported to produce Pt-Al pillared clays [39,40] and wet ion-exchange, a method previously described in the literature to obtain Rh-Al pillared clays [41]. In this work, the content in Pd tested was within the 0.5-5 wt% range, which is the most commonly used in the literature [39,[42][43][44][45].…”

Hydrodechlorination of 4-chlorophenol in water using Rh–Al pillared clays

“…They are constituted by a two-dimensional network of interconnected micropores while the stacking of the clay lamellas creates mesopores, pillared clays possessing a bimodal pore structure [31]. Al-pillared clays have been used as supports of a great diversity of noble and transition metals and their use in different catalytic systems is extensively reported in the literature: Ni for hydrogenation of benzene [32], Pt for hydrogenation of adipic ester [33] or hydroconversion of heptane [34], Ru for hydrogenation of 1-butene [35], Ag for reduction of NO with NH 3 or C 2 H 4 [36] and even bimetallic systems as Pd-Fe for dehalogenation of aryl halides [37].…”
