摘要: Abstract Zeolites Y, ZSM-5, beta, mordenite and LTL were converted into hierarchical meso-microporous catalysts applying the surfactant templating strategy resulting materials utilised as for esterification aldol condensation reactions production of second generation biofuels platform chemicals from biomass derived molecules. The relationship between catalytic performance accessibility active sites in zeolites was examined using FTIR spectroscopy adsorbed pyridine, 2,4,6-trimethylpyridine 1,3,5-triisopropylbenzene. It found that oleic acid can be enhanced by presence strong their improved accessibility. In reaction, furfural conversion over also increased compared to parent zeolites. However, K-forms studied exhibited a higher selectivity toward desired reaction products comparison with H-forms. Overall, mesostructured demonstrated an result increasing zeolite sites.
