title: Catalytic pyrolysis of waste mandarin over nanoporous materials.
abstract: Catalytic pyrolysis of waste mandarin was performed using nanoporous catalysts. AI-MCM-41 and Meso-MFI, which had different acid characteristics, were used. In addition, the characteristics of Pt/Meso-MFI were compared with those of Meso-MFI. To analyze the characteristics of the catalyst samples, Brunauer-Emmett-Teller surface area, temperature programmed desorption of NH3, and N2 adsorption-desorption analyses were performed. In addition, pyrolysis gas chromatography/mass spectrometry was used to facilitate the direct analysis of the pyrolytic products. The products obtained from catalytic pyrolysis contained a greater amount of valuable components than did those obtained from non-catalytic pyrolysis, indicating that catalytic pyrolysis improved the quality of the bio-oil. Additionally, valuable products such as furan and aromatic compounds were produced in greater quantities when Meso-MFI was used. When Pt/Meso-MFI was used, the amounts of furan and aromatic compounds produced increased even further.
