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.

Pyrolysis Catalyst

Experiments on the catalytic pyrolysis of corn stover and catalytic reforming of pyrolysis vapors were conducted in a tubular fixed-bed reactor. The influence of reaction temperature, pyrolysis catalysts, dosage of pyrolysis catalysts and dosage of reforming catalysts were investigated. The results showed that with the increase of reaction temperature, the oil and char yields decreased and the gas yield increased. The highest-quality bio-oil was achieved at the reaction temperature of 400 °C, and dolomite showed a best performance on the biomass pyrolysis compared to other catalysts. Besides, When the dosage of pyrolysis catalyst was 1 g, the relative content of aromatic was 43.92 wt% and the relative content of acids was 47.58 wt%, and when the dosage of reforming catalyst was 2 g, the relative content of aromatic was 34.1 wt% and the relative content of acids was 58.7 wt%.

Abstract The low yield and poor fuel properties of bio-oil have made the pyrolysis production process uneconomic and also limited bio-oil usage. Proper manipulation of key pyrolysis variables is paramount in order to produce high-quality bio-oil that requires less upgrading. In this research, the pyrolysis of pig hair was carried out in a fixed-bed reactor using a calcium oxide catalyst derived from calcination of turtle shells. In the pyrolysis process, the influence of three variables—temperature, heating rate and catalyst weight—on two responses—bio-oil yield and its higher heating value (HHV)—were investigated using Response Surface Methodology. A second-order regression-model equation was obtained for each response. The optimum yield of the bio-oil and its HHV were obtained as 51.03% and 21.87 mJ/kg, respectively, at 545oC, 45.17oC/min and 2.504 g of pyrolysis temperature, heating rate and catalyst weight, respectively. The high R2 values of 0.9859 and 0.9527, respectively, obtained for the bio-oil yield and its HHV models using analysis of variance revealed that the models can adequately predict the bio-oil yield and its HHV from the pyrolysis process.

Pyrolysis Of Biomass

Due to the rapid growth of energy consumption, fossil-based fuel is at the verge of extinction. Hence, the world needs new energy to substitute for the non-renewable energy resources. Various biomass resources have been discussed by virtue of the ability of generating alternative fuels, chemicals and energy-related products. To date, the utilization of biomass is mainly thermochemical conversion which involves combustion, gasification and pyrolysis. The focus, currently, is on the catalytic pyrolysis of biomass. A variety of reactors are designed and many new catalysts for the yields of liquid products and upgrading of bio-oil are investigated. Different reactors have their own unique characteristics, and fixed bed reactor is not complicated and can be controlled easily but is difficult to upsize. Fluidized bed has a good suitability for different kinds of biomass but is more complex in structure and more difficult to control. Compared with non-catalytic pyrolysis, the quality of bio-oil improves considerably in the presence of a catalyst. Different catalysts exert different effects on the upgrading of bio-oil. HZSM-5 can reduce a vast output of acid compounds and increases hydrocarbon yields. Au/Al2O3 catalyst leads to an increase of H2 yield. All the catalysts can promote the upgrading of pyrolysis products. Optimal yields and the best quality of bio-oil can be obtained by an appropriate reactor with a proper catalyst.
