Biocrude from biomass: pyrolysis of cottonseed cake

Fixed-bed pyrolysis experiments have been conducted on a sample of cottonseed cake to determine the possibility of being a potential source of renewable fuels and chemicals feedstocks, in two different reactors, namely a tubular and a Heinze retort. Pyrolysis atmosphere and pyrolysis temperature effects on the pyrolysis product yields and chemical composition have been investigated. The maximumm oil yield of 29.68% was obtained in N₂ atmosphere at a pyrolysis temperature of 550°C with a heating rate of 7°C min⁻¹ in a tubular reactor.
