Mesoporous materials produced from zeolite HBeta, (MMZHBeta) with different Si/Al ratios were synthesized and applied for the first time to the catalytic pyrolysis of Geodae-Uksae 1, a new energy crop discovered in South Korea. The non-catalytic pyrolysis and in-situ catalytic pyrolysis of Geodae-Uksae 1 were tested rapidly using a pyrolyzer-gas chromatography/mass spectrometry/ flame ionization detector/thermal conductivity detector. The main pyrolyzates of Geodae-Uksae 1 consisted of levoglucosan, acetic acids, furans, and phenolics, which were upgraded efficiently into furans and aromatics using the MMZHBeta catalysts. Between the MMZHBeta catalysts, MMZHBeta (25) produced larger amounts of furans and aromatics than MMZHBeta (300) owing to its higher acidity. The increase in the catalyst to biomass ratio (from 2/1 to 6/1) and reaction temperature (from 500 to 600 °C) enhanced the formation of aromatics.
