“…The gas yield decreased first and increased noticeably compared to the non-catalyst test [29]. However, Zhou [30] studied catalytic pyrolysis of rice husk by mixing with zinc oxide and it was observed that the use of catalyst decreased the bio-oil yields. In this experiment, Na + presented in the catalyst is very small and it can penetrate into the rice husk textures to react with cellulose, hemicellulose and lignin under heating.…”

“…Zinc oxide (ZnO) catalyst was used for catalytic pyrolysis of rice husks to produce bio-oil in a fixed-bed reactor. ZnO catalyst decreased the amount of undesired oxygenated compounds in bio-oils [63]. Boric oxide (B 2 O 3 ) selectively eliminated 50%-80% of the hydroxyl and methoxy groups in the bio-oil produced from empty palm oil fruit bunch and oil palm fronds in a fixed-bed reactor at 400 • C [58].…”

Abstract:The massive consumption of fossil fuels and associated environmental issues are leading to an increased interest in alternative resources such as biofuels. The renewable biofuels can be upgraded from bio-oils that are derived from biomass pyrolysis. Catalytic cracking and hydrodeoxygenation (HDO) are two of the most promising bio-oil upgrading processes for biofuel production. Heterogeneous catalysts are essential for upgrading bio-oil into hydrocarbon biofuel. Although advances have been achieved, the deactivation and regeneration of catalysts still remains a challenge. This review focuses on the current progress and challenges of heterogeneous catalyst application, deactivation, and regeneration. The technologies of catalysts deactivation, reduction, and regeneration for improving catalyst activity and stability are discussed. Some suggestions for future research including catalyst mechanism, catalyst development, process integration, and biomass modification for the production of hydrocarbon biofuels are provided.

“…It is important to note that bio-oil was not dried before IR spectrum so the peak around 3353 cm −1 may contain some contamination of water content. Alkanes are found Gercel [45] and Zhou et al [46] in the literature. The bio-oil obtained from the fast pyrolysis of cotton stalk is in the homogenous phase and dark brown in color.…”

Fast pyrolysis was used to convert waste biomass into bio-oil, which has a benefit of storage and transportation with the potential as a fossil oil substitute. Pakistani cotton stalk was pyrolyzed in a bench-scale bubbling fluidized bed reactor. The effect of reaction conditions such as temperature and feed size on the bio-oil, char and gas yields was investigated. The optimal pyrolysis temperature for the production of bio-oil was 490 • C which gave the maximum yield (36 wt%) of product at feed size of 1.0 mm. Bio-oil yield increased with the increase in temperature, while the yield of char decreased. The various properties of bio-oil attained under these pyrolysis conditions were defined. Chemical composition of bio-oil was determined using FTIR and GC-MS analysis, and major chemical compounds were phenols, carboxylic acids, ketones, aldehydes, furans and sugars.
