Abstract
Wild reed was pyrolyzed over two nanoporous SBA-15 catalysts with different acid characteristics: Si-SBA-15 and Al-SBA-15. Al was grafted on Si-SBA-15 to increase the acidity and enhance the catalytic activity. Fast pyrolysis was carried out using a pyrolysis-gas chromatography/mass spectrometry system at 550°C for real-time analysis of the products. Significant improvement of the product bio-oil quality was attained by catalytic reforming over nanoporous Al-SBA-15. The fraction of total oxygenates was reduced because of the decrease in the fraction of ketones, aldehydes, and carboxylates, which deteriorate the fuel quality of bio-oil. On the other hand, the fractions of furans and aromatics, which are the chemicals with high value-added, were increased by the catalytic reforming. The catalytic activity of Al-SBA-15 was considerably higher than that of Si-SBA-15 because the incorporation of Al increased the catalyst acidity.
