Study of Catalytic Pyrolysis of Chlorella with y-Al2O3 Catalyst

摘要：

　　Chlorella samples were pyrolysed in a fixed bed reactor with γ-Al2O3 or ZSM-5 molecular sieve catalyst at 600℃.Liquid oil samples was collected fi om 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-A12O3 shows a lower acidity.The γ-A12O3 catalyst shows promise for production of high-quality bio-oil from algae via the catalytic pyrolysis.
