Catalytic co-pyrolysis of waste particle board and polyproplylene over nanoporous Al-MCM-41 catalysts.

Catalytic co-pyrolysis of particle board, a waste wood biomass, and polypropylene (PP), a petroleum-based plastic, was carried out with a mixing ratio of 1:1 over a representative mesoporous material, Al-MCM-41 catalyst. The Si/Al ratios of the Al-MCM-41 catalysts were controlled at 20 and 80 to investigate the effect of the acidity of the catalyst. The characterization of the catalyst was performed by X-ray diffraction, N2 adsorption-desorption, and NH3 temperature-programmed desorption.

Pyrolysis and co-pyrolysis of Laminaria japonica and polypropylene over mesoporous Al-SBA-15 catalyst.

The catalytic co-pyrolysis of a seaweed biomass, Laminaria japonica, and a typical polymer material, polypropylene, was studied for the first time. A mesoporous material Al-SBA-15 was used as a catalyst. Pyrolysis experiments were conducted using a fixed-bed reactor and pyrolysis gas chromatography/mass spectrometry (Py-GC/MS).

Catalytic conversion of waste particle board to bio-oil using nanoporous catalyst.

Unlabelled: The catalytic pyrolysis of waste wood including the particle board was examined by pyrolysis gas chromatography/mass spectrometry (Py-GC/MS) to produce bio-oil. Three different catalysts with a nanoporous structure, Al-MCM-48, Meso-MFI, and Pt-Meso-MFI, were used and their performances were compared. When MCM-48 was used, the quality of the bio-oil product was better than that prepared by non-catalytic pyrolysis but the improvement was limited due to its weak acid sites.
