Abstract

Highlights: The qualities of thermal and catalytic bio-oils (from durian rind) were compared. High-surface-area amorphous microporous silica-alumina catalyst was prepared. Silica-alumina catalyst promoted the formation of hydrocarbon at 400 °C. Silica-alumina catalyst enhanced the formation of aromatic compounds at 600 °C. Deoxygenation degree of bio-oil produced with silica-alumina at 600 °C reached 94%. Abstract: Silica-alumina catalyst was prepared and used in the catalytic fast pyrolysis of durian rind in a drop-type two-stage reactor. The effects of catalytic temperature (400 °C–600 °C) and catalyst-to-durian rind ratio (1:30–3:30) were evaluated. Bio-oil yield was increased with increased catalytic temperature due to considerable dehydration process, but it was reduced with high catalyst loading due to the overcracking of organics into light gases. Silica-alumina catalyst possessed good selectivity and the products changed according to the temperature. The major components in bio-oil were hydrocarbons, furan derivatives, and aromatic compounds at 400 °C, 500 °C, and 600 °C, respectively. The hydrogen and carbon contents of bio-oil were reduced with high catalyst loading due to the overcracking of organics, and the deoxygenation process became unfavorable. The silica-alumina catalyst worked well in catalytic fast pyrolysis of durian rind, and the condition may be adjusted based on the desired products.
