Abstract
Fibrous silica BEA zeolite (FBEA) was synthesized by microemulsion method and tested for benzene methylation. The FESEM and N2physisorption verified that the FBEA exhibited a dendrimeric silica fiber morphology with large surface area and high ratio of mesopores and micropore volume. While the FTIR pre-adsorbed pyridine revealed that the FBEA possessed low Brönsted acid sites compared to commercial beta zeolite. The catalytic testing at 300 °C showed that FBEA was catalytically active towards benzene methylation to produce toluene with 97.8% conversion and 55.5% yield. It is suggested that the fibrous morphology might increase the mesopores volume and reduce the acidity, hence, improves the benzene alkylation reaction.
