Bio-oil can serve as an alternative fuel source or resource to extract high value-added chemicals. This paper focuses on the effect of six types of biomass (rape straw, corn straw, walnut shell, chestnut shell, camphor wood, and pine wood) and ZnCl2 catalyst on the bio-oil yield and chemicals in the bio-oil, including aldehydes, ketones, and four high-value chemicals (1-hydroxy-2-butanone, propionaldehyde, 5-HMF, 2(5H)-furanon). The results showed that the yields of bio-oil decreased when the ZnCl2 was the catalyst. The ZnCl2 promoted the production of aldehydes and ketones. The higher contents of aldehydes and ketones were obtained from camphor and pine wood, at 58.9 wt% and 42.0 wt%, respectively. The ZnCl2 catalyst exhibited an active influence on the production of 1-hydroxy-2-butanone, propionaldehyde, 5-HMF, and 2(5H)-furanon. Compared with the non-catalytic pyrolysis, the content of 1-hydroxy-2-butanone and 2(5H)-furanone in bio-oil increased by 936% and 612%, respectively. The contents of propionaldehyde and 5-HMF in catalytic bio-oil were the highest from rape straw and increased by 193% and 86%, respectively.

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.

The market demand of bio-fuel is 11,8 billion litters based on recent reported data. Hence, with the high demand of bio-fuel, the bio-fuel production utilizing rice husk can be one of the solutions. Beside, bio-oil can be produced by pyrolysis process utilizing rice husk as the feedstock. In this research, the optimization condition in producing bio-oil from rice husk by catalytic pyrolysis process was studied. The effect of catalyst type (H-β, H-Y, HZSM-5), catalyst loading (1wt%, 5wt%, 12wt%), temperature (400-500°C) and flow rate (60-100ml/min) were investigated through repetitive experiments using L9 Taguchi Orthogonal Array. The highest liquid yield of 38wt% was obtained at the optimum conditions with temperature of 500°C with nitrogen flow rate of 60ml/min and 12wt% of H-ZSM-5.
