Study of Catalytic Pyrolysis of Chlorella with γ-Al₂O₃ Catalyst

Abstract:

Chlorella samples were pyrolysed in a fixed bed reactor with γ-Al₂O₃ or ZSM-5 molecular sieve catalyst at 600°C. Liquid oil samples was collected from pyrolysis experiments in a condenser and characterized for water content, kinematic viscosity and heating value. In the presence of catalysts , gas yield decreased and liquid yield increased when compared with non-catalytic pyrolysis at the same temperatures. Moreover, pyrolysis oil from catalytic with γ-Al₂O₃ runs carries lower water content and lower viscosity and higher heating value. Comparison of two catalytic products, the results were showed that γ-Al₂O₃ has a higher activity than that of ZSM-5 molecular sieve. The acidity distribution in these samples has been measured by t.p.d, of ammonia, the γ-Al₂O₃ shows a lower acidity. The γ-Al₂O₃ catalyst shows promise for production of high-quality bio-oil from algae via the catalytic pyrolysis.
