“…The bio-oil product decreased at pyrolysis temperatures of 450 to 550 °C due to the decrease of the organic and specific products and secondary cracking of volatiles at temperatures above 500 °C [18]. Above this temperature, the bio-oil yield decreased with the conjunction of releasing more gas products due to secondary cracking [19]. It was concluded that the optimum temperature for bio-oil production was 450 o C in the present experimental conditions.…”

Pyrolysis of palm kernel shell in a fixed-bed reactor was studied in this paper. The objectives were to investigate the effect of pyrolysis temperature and particle size on the products yield and to characterize the bio-oil product. In order to get the optimum pyrolysis parameters on bio-oil yield, temperatures of 350, 400, 450, 500 and 550 °C and particle sizes of 212-300 µm, 300-600 µm, 600µm-1.18 mm and 1.18-2.36 mm under a heating rate of 50 °C min -1 were investigated. The maximum bio-oil yield was 38.40% at 450 °C with a heating rate of 50 °C min -1 and a nitrogen sweep gas flow rate of 50 ml min -1 . The bio-oil products were analysed by Fourier transform infra-red spectroscopy (FTIR) and gas chromatography-mass spectroscopy (GCMS). The FTIR analysis showed that the bio-oil was dominated by oxygenated species. The phenol, phenol, 2-methoxy-and furfural that were identified by GCMS analysis are highly suitable for extraction from the bio-oil as value-added chemicals. The highly oxygenated oils need to be upgraded in order to be used in other applications such as transportation fuels.

Bio-Oil Production from Fast Pyrolysis of Cotton Stalk in Fluidized Bed Reactor

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.

Renewable Sustainable Energy 6, 053142 (2014); 10.1063/1.4900550 Pyrolysis kinetics of de-oiled cakes by thermogravimetric analysisDe-oiled cakes, a source of biomass in the form of agriculture residue, could be an ideal source for the production of bio-fuels that can be substituted with conventional fossil fuels. In this study, pyrolysis of mahua de-oiled cake (Madhuca indica) was carried in a semi-batch reactor at the temperatures of 350, 400, 450, 500, 550, and 600 C. The optimum temperature at which maximum yield of 41.36% (by weight) liquid product obtained was 550 C. Empirical formula of the bio-oil was established as CH 1.379 N 0.0576 S 0.004 O 0.614 . The thermal degradation of mahua de-oiled cake was studied in inert atmosphere from ambient temperature to a temperature of 600 C at a heating rate of 25 C min À1 . The chemical composition of bio-char was investigated by using SEM-EDX and its heating value was determined to be 26 MJ/kg. Characterization showed that the bio-oil obtained can potentially be valued as fuel and chemical feedstock.
