“…1). This reaction has been studied with pure reactants and in the presence of toluene or water as solvent and solid acids such as commercial Amberlyst 15 resin 23, montmorillonite clay catalysts 24, zeolite ZSM‐5 in both Na‐ and H‐forms 25, and carbon‐based acids as catalysts 26. A DES yield of 64 % was obtained with an Al 3+ ‐montmorillonite catalyst and toluene as solvent after 8 h of reaction 24.…”

Esterification of Succinic Acid Using Sulfated Zirconia Supported on SBA‐15

Catalytic esterification of succinic acid with ethanol to obtain diethyl succinate (DES), a nontoxic plasticizer, is reported. Three sulfated zirconias supported on SBA‐15 [SZ‐SBA‐15(X)] with Si/Zr molar ratios (X) of 10, 20, and 30 were synthesized and characterized. N2 adsorption/desorption isotherms and X‐ray diffraction patterns evidenced preservation of the ordered mesoporous structure of the catalysts after incorporation of Zr. Yields of DES greater than 85 % were obtained at the final reaction time by using SZ‐SBA‐15(10) and SZ‐SBA‐15(20) catalysts, which were higher than those achieved with Amberlyst 36. Reuse of the SZ‐SBA‐15(20) catalyst showed that, even though the structure of the support was preserved, decreases in sulfur concentration and in the DES yield occurred.

Utilization of zeolite catalysts in biomass exploitation: a minireview

2023

View full text Add to dashboard Cite

This minireview discusses the use of zeolites as catalysts in all stages of lignocellulose biomass (LCB) valorization process. A summary of some synthesis and characterization methods for zeolitic materials is provided. Utilization of various active sites of zeolites is explored with the focus on Brønsted and Lewis acid sites and the importance of hierarchical structures in the processes involving bulky biobased molecules. Zeolites modified by top-down methods, specifically desilication with various basic reagents, are good candidates for applications in LCB valorization. Some novelty methods such as a dry milling for incorporating metal nanoparticles into zeolite structure are mentioned. An overview of studies utilizing zeolites in processes such as catalytic pyrolysis of LCB, acid-catalyzed hydrolysis and reactions of platform molecules (ethanol, furans, glycerol, bio-hydrocarbons, lactic acid, succinic acid, levulinic acid, sorbitol, xylitol) is discussed. Special attention is dedicated to reactions of biomass-derived alcohols and value-added chemicals produced from them, e.g., esters. The most successful industrial zeolite application—fluid catalytic cracking—is also summarized for comparison. Challenges of zeolite stability in reactions carried out in liquid water conditions, as well as possibilities of catalyst stabilization, e.g., with extra-framework aluminum, or hydrophobization of the surface, are explored.
