“…The maximum oil yield was 27.60% occurred at 550°C with the nitrogen flow-rate of 100 cm 3 min −1 and the heating rate of 50°C min −1 . Guo et al (2011) studied the pyrolysis of rice husk and the thermal behavior of bio-oil by means of a thermogravimetric analyzer in conjunction with a Fourier transform infrared spectrometer (TG-FTIR). The bio-oil yield was 46.36% and the gas yield was 27% at 520°C.…”

Pyrolysis is an important thermochemical method to convert biomass into bio-oil. In this study, the pyrolysis of sugarcane bagasse in a CO 2 atmosphere under conventional and microwave-assisted heating is investigated to achieve CO 2 utilization. In the microwave pyrolysis, charcoal is used as the microwave absorber to aid in pyrolysis reactions. The results indicate that the yields of pyrolysis products are greatly influenced by the heating modes. In the conventional heating, the prime product is bio-oil and its yield is in the range of 51-54 wt%, whereas biochar is the major product in microwave-assisted heating and its yield ranges from 61 to 84 wt%. Two different absorber blending ratios of 0.1 and 0.3 are considered in the microwave pyrolysis. The solid yield decreases when the absorber blending ratio decreases from 0.3 to 0.1, while the gas and liquid yields increase. This is attributed to more energy consumed for bagasse pyrolysis at the lower blending ratio. Hydrogen is produced under the microwave pyrolysis and its concentration is between 2 and 12 vol%. This arises from the fact that the secondary cracking of vapors and the secondary decomposition of biochar in an environment with microwave irradiation is easier than those with conventional heating.

“…However, other problems arise when the coal is mixed with biomass. Biomass contains high amount of oxygen so that the pyrolytic oil contains quite high amount of oxygenated compound with low oil quality [21][22][23]. The use of catalysts such as zeolite may improve the oil quality by upgrading process [24][25][26].…”

The liquid product (bio-oil and aqueous) from pyrolysis of biomass such as microalgae contains a wide variety of compounds which makes it a potential source of biofuels and bio-chemicals. However, its complex composition limits its direct use as such. In this paper, fractional distillation at atmospheric conditions was explored as a technique to upgrade the quality of the pyrolyticbio-oil and aqueous liquid product (ALP) distillate fractions. By fractional distillation, the liquid product components were separated to relatively simpler distillate fractions which were then analyzed in terms of moisture, energy content, elemental and chemical compositions to assess their potential uses as fuel substitute or source of bio-chemicals. Fractional distillation of algal bio-oil resulted to 19% wt light fractions (BF1 and BF2), 7% wt middle fractions (BF3 and BF4), 51% wt heavy fraction (BF5) and 23% wt non-distillate residue. BF1 and BF2 were found to be comparable to diesel and BF6 to heavy fuel oil using van Krevelen diagram. For the ALP, the distillate fraction obtained at 150-180 o C (AF5) was found to have a heating value (about 24 MJ/kg) which is higher than methanol and wood-derived bio-oils. It was also found to contain various components such as carboxylic acids and carboxylate esters which could be further processed to produce value-added chemicals. The separation factor, β, showed that complete separation can be achieved by fractional distillation for some compounds such as high molecular weight olefins and naphthenes.
