Abstract
Nanostructured catalysts were successfully prepared by acidification of diatomites and the regeneration of used FCC catalysts. The obtained samples were characterized by IR, XRD, SEM, EDX, MAS-NMR (27Al and 29Si), NH3-TPD and tested in catalytic pyrolysis of biomass (rice straw). The results showed that the similar bio-oil yield of 41,4% can be obtained by pyrolysis in presence of catalysts at 450°C as compared to that of the pyrolysis without catalyst at 550°C. The bio-oil yield reached a maximum of 42,55 % at the pyrolysis temperature of 500°C with catalytic content of 20%. Moreover, by catalytic pyrolysis, bio-oil quality was better as reflected in higher ratio of H/C, lower ratio of O/C. This clearly indicated high application potential of these new nanostructured catalysts in the production of bio-oil with low oxygenated compounds.
