Catalytic Conversion of Undaria Pinnatifida Over Nanoporous Materials Using Py-GC/MS
Catalytic pyrolysis of Undaria Pinnatifida was carried out over a nanoporous Al-SBA-15 catalyst for the first time. Pt nanoparticles were added to Al-SBA-15 to generate a Pt/Al-SBA-15 catalyst. The effect of the addition of the Pt nanoparticles on the catalytic pyrolysis was investigated. For rapid product analysis and catalyst evaluation, a pyrolysis-gas chromatography/mass spectrometry was used. The characteristics of the catalysts were analyzed using X-ray diffraction, nitrogen adsorption–desorption, transmission electron microscope, NH3 temperature programmed desorption, and inductively coupled plasma optical emission spectrometer. Compared to the non-catalytic pyrolysis, catalytic pyrolysis over Al-SBA-15 produced a higher-quality bio-oil with a high stability and a low oxygen content. When Pt/Al-SBA-15 was used, compared to Al-SBA-15, the improvement of bio-oil quality was more profound; the yield of high-value-added aromatics increased, while the yields of acids and oxygenates decreased.
