Abstract:

Flexible technologies producing different fuels and chemicals will be needed in order to overcome new operational drawbacks for the processing of organic feedstock such as the pyrolysis oil that presents a complex composition and very heterogeneous properties depending on the nature of the feedstock and its production process. The present work focuses on the syngas production by catalytic steam reforming of the entire pyrolysis oil at low steam to carbon molar ratio (S/C). The decoupling of the evaporation of pyrolysis oil from the catalytic steam reforming allowed the optimisation of every stage and thus the overall process. The steam reforming was carried out at 850 ºC, GC1HSV ~ 1500 h­1 and S/C ratios ~ 1.0 generating ~ 1.5 m3STP/kg of synthesis gas with H2/CO molar ratio ~ 2. The prepared Ni/Al­Mg catalyst used in the present work resulted in an improved performance in comparison to a commercial naphtha reforming catalyst as the last one showed irreversible deactivation after regeneration test.
