“…Hydrocracking of FT waxes, i.e. , long paraffinic chains (C 21 ), 51 provides high-end middle distillates with low sulphur and aromatics content. 52 Regarding the catalysts, NiMo and NiW supported on solid acids are particularly well suited for producing middle distillates.…”

“…HC is a catalytic cracking process whereby the C-C bonds in aromatics and olefins, i.e., long hydrocarbon chains, are broken by the addition of H2 to yield naphthenes and alkanes. 49,50 Hydrocracking of FT waxes, i.e., long paraffinic chains (>C21), 51 provides high-end middle distillates with low sulphur and aromatics content. 52 Regarding the catalysts, NiMo and NiW supported on solid acids are particularly well suited for producing middle distillates.…”

“…52 Regarding the catalysts, NiMo and NiW supported on solid acids are particularly well suited for producing middle distillates. 52 However, Pd and Pt-loaded catalysts, which have high hydrogenation/dehydrogenation activity for heavy hydrocarbon cracking, could also be used owing to the sulphur-free nature of FT waxes 51,53,54 . Thus, we considered a platinum-based catalyst supported on amorphous silica-alumina in this work.…”

Modulation of the acidity of a vermiculite and its potential use as a catalytic support

et al. 2020

View full text Add to dashboard Cite

The modulation and characterization of the acidity of a vermiculite was carried out, which was modified by delamination by means of hydrothermal and acid treatments with the subsequent incorporation of AlZr and AlCe species to modulate the acidity. The effect of these species was evaluated regarding the structural (XRD, XPS and IR), textural (N 2 sortometry), and acidity properties (NH 3 -TPD, NH 3 -DRIFTS and CO adsorption at low temperature). The catalytic performance was studied in the dehydration-dehydrogenation reactions of 2-propanol and the hydro-conversion of decane, which generate important information about the acidity properties such as the type, number and strength of acidic sites. The correlation between the number, type and acid strength with the catalytic behavior allowed to establish the important effect regarding the nature of the mineral, its method of delamination and the nature of the incorporated cation, thus generating tools for controlled processes for the potentiation of the acidity of new supports from raw vermiculite.
