A study on catalytic pyrolysis of biomass with Y-zeolite based FCC catalyst using response surface methodology

► Reaction temperature was the most significant independent variable. ► Higher WHSV increases the organic liquid yield. ► Coke formation decreases at higher temperatures (>500 °C) and WHSV (>2 h−1). ► Decarboxylation reaction decreases at higher temperatures. ► Viscosity of the bio-oils increases with increase in temperature.
