Descripción
Benzene, toluene, and xylene (BTXs) are the major commodity chemicals serving a wide range of industries with large global economic impact and are currently obtained exclusively from petroleum feedstock. Alternative renewable sources from biomass are raised as a solution to satisfy the pressing needs for a fully sustainable bio-commodities industry. For this reason, the chemistry of materials has focused on the synthesis of catalysts that can transform biomass into renewable chemical compounds of interest. In this work, the SBA-15 material was modified with Al to incorporate a specific Br/Le acid sites ratio to make a low-cost tailor-made catalyst for the aromatization reaction of furanic dienes and dienophiles from renewable biomass sources. In order to correlate the catalytic activity of materials with their structure and nature, the solids werecharacterized by several techniques such as XRD, TEM, ICP, N2 physisorption and FT-IR of adsorbedpyridine. The goal of this work was to maximize the production of p-xylene (PX) by fine-tuning the Alcontent in SBA-15 and optimizing the reaction conditions. The presence of Lewis (Le) and Brønsted (Br) acid sites in Al-SBA-15 materials with different Al contents was determined and the catalysts were evaluated in the aromatic reaction of 2,5-dimethylfuran with ethylene. The optimal combination of Le sites, to produce the first cycloaddition, and Br sites, for subsequent dehydration, was achieved with the Al(1.28)SBA-15 catalyst. After optimization of main reaction parameters (i.e., pressure, temperature and reagents and catalyst concentrations), a 42% yield of p-xylene was achieved and maintained even after three consecutive re-cycles of solid catalyst. Finally, the possible extended scope of this catalytic system for producing toluene and trimethylbenzene from the corresponding starting reactants was also evaluated.
