Bio-oils can be transformed into transportation fuels and valuable chemical products by means of catalytic processing. The conversion of bio-oil obtained from soybean shell over high alumina, SiO2-Al2O3 active matrices formulated to facilitate the pre-cracking of bulkyhydrocarbon molecules in FCC resid processing, isstudied in this work. Results are compared against thoseobtained when Y zeolite was incorporated to the matrices in order to reproduce commercial typical FCC catalysts and evaluate the effect of the main catalyst components. The results suggest that the matrix in FCC catalysts may play a key role in the conversion of bio-oils into hydrocarbons. The addition of Y zeolite to form compound catalysts with silica-alumina matrices improves bio-oil deoxygenation and reduces coke yield significantly. Another consequence was that the selectivity to olefins decreased and the selectivity to aromatics increased for hydrocarbons in the gasoline boiling range. The matrices favor primary deoxygenation and cracking reactions on the bio-oil components, while the zeolite promotes the conversion of intermediate olefinic products into aromatics. The composition of the matrices does not show a significant influence on the selectivity to the liquid products.
