Enhancement of biofuel quality via conventional and catalytic co-pyrolysis of bamboo with polystyrene in a bubbling fluidized bed reactor: Coupled experiments and artificial neural network modeling

•Effect of operating parameters and catalysts on co-pyrolysis of bamboo/PS (80/20) blend was investigated.•Synergistic effect of co-pyrolysis was proved via theoretical and experimental values of various properties.•Co-pyrolysis reduced the O content and improved HHV of oil under PS-derived H2-donor.•Dolomite was the most effective catalyst in improving HHV and pH of oil among catalysts.•ANN with 15 neurons in the hidden layer was the best model for fitting experimental data.
