“…Furthermore, it is noted that these samples had the most intense d 100 peak, with this being another point indicative of the presence of nickel, as this peak may be related to the transformation of nickel into its respective oxide after the calcination step. 45 Another point observed is the continuation of the characteristic peaks of SBA-15 even after impregnation of the metal and new calcination, suggesting that this support, after these operations, maintained the degree of ordering of its structure. 41…”

“…The proportion of fatty acid in WCO decreased when MeO-SBA-15 catalysts were used, as these mesoporous catalysts promote the formation of hydrocarbon through decarbonylation, cracking, and decarboxylation [2]. The ability of SBA-15 catalyst to produce aliphatic hydrocarbons was reported by Ozbay et al, who investigated the catalytic pyrolysis of banana peel waste using Al-modified SBA-15 and found that the compositions of the bio-oil catalyzed using Al-SBA-15 materials (15 wt %) contained a high aliphatic fraction up to 55.1%, while a lower fraction of aromatics at 25.1% was achieved [34]. This may be due to the larger pore characteristics of SBA-15, which facilitate the production of linear/cyclic hydrocarbons.…”

In this work, Sacha inchi (Plukenetia volubilis L.) residues were used as biomass feedstocks in catalytic upgrading pyrolysis with SBA-15, which is a substance synthesized from coal fly ash (CFA), using alkali fusion, followed by hydrothermal treatment (SBA-15-FA). The catalytic activity of fly ash-derived SBA-15 was investigated through the fast pyrolysis of Sacha inchi residues for upgrading the pyrolysis vapors using the analytical pyrolysis-GC/MS (Py-GC/MS) technique. The pyrolysis temperature was set at 500 °C and held for 30 s while maintaining the Sacha inchi residues to catalyst ratios of 1:0, 1:1, 1:5, and 1:10. In addition, the SBA-15s synthesized from chemical reagent and commercial SBA-15 were evaluated for comparison. The non-catalytic fast pyrolysis of Sacha inchi (SI) mainly consisted of fatty acids (46%), including chiefly linoleic acid (C18:2). Other compounds present were hydrocarbon (26%) and nitrogen-containing compounds (8.7%), esters (9.0%), alcohols (6.4%), and furans (3.6%). The study results suggested that the SBA-15-FA showcased a high ability to improve aliphatic selectivity (mainly C5–C20) and was found to be almost 80% at the biomass to catalyst ratio of 1:5. Moreover, the increase in catalyst contents affected the enhancement of hydrocarbons yields and tended to promote the deoxygenation reaction. Interestingly, the catalytic performance of SBA-15 derived from fly ash could be compared to that of the commercial SBA-15 in terms of producing hydrocarbon compounds as well as reducing oxygenated compounds.

“…It could be ascribed to the "cleaning" of the SBA-15 channels by dissolving very small contaminations and pore walls [39]. The slightly reduced pore size of Pd/AlF-Y series is caused by Al species existed inside SBA-15 channels [40].…”

SBA-15 was modified via post-treatment with (NH 4 ) 2 SiF 6 and (NH 4 ) 3 AlF 6 solution (NSF-T and NAF-T) and applied as support of Pd catalysts for the hydrogenation of 2-ethyl-anthraquinone (EAQ). The characterization results revealed that F could be incorporated into the framework of SBA-15 by forming Si-F bond and the amount of F increased as the molar ratio of F in treating solution to Si species in SBA-15 (F/Si) increased from 0.1 to 0.4 for NSF-T and 0.3 to 0.6 for NAF-T. At the same F/Si, the incorporated amount of F was larger with NSF-T than with NAF-T, and the latter could simultaneously create acid sites in catalysts. The hydrophobicity of catalysts could be effectively improved by incorporating F into SBA-15 supports, which favored the catalytic performance. The catalyst on SBA-15 treated by NSF with F/Si of 0.3 exhibited the high initial activity (0.24 molH 2 •gPd −1 •min −1 ) and selectivity (95.5%).
