“…As the particle-size grew, so did the yield of bio-char. Enhanced particle-size initiates a temperature gradient, that limits the heat transfer rate, will increase reaction completion time, favoring secondary reactions, and lowering bio-oil output [53]. These findings were supported by bearings in the literature [5456] addressing the effect of particle-size in pyrolysis.…”

Global economic development has a direct link to energy usage. The growth in energy usage implies a rise in gross domestic product (GDP). Crude oil will account for 31.23 percent of global energy consumption in 2020, compared to 6.83 percent for hydroelectricity, 4.30 percent for nuclear, 27.18 percent for coal, and 24.70 percent for natural gas. Crude oil prices climbed sharply and fluctuated in an unpredictable manner, causing the rate of economic growth to fluctuate. In a typical scenario, oil reserves will disappear over the next 40-50 years [1]. In any case, renewable energy is making strenuous efforts to replace fossil fuels and close the energy deficit.

“…It is observed that agriculture residues has found as practical choice to produce bio-oil [33,58]. Madhu et al [59] performed the fast pyrolysis of cotton shell in a fluidized bed reactor at a laboratory scale. The maximum bio-oil and char yield of 51.2% and 18.4%, respectively obtained at a temperature of 450℃.…”

The production of biofuel from agricultural crop residue via fast pyrolysis is becoming a popular option. It can help to build a robust renewable fuel market and ensure environmental sustainability. In this study, the widely available maize straw was used for the production of bio-oil in a fluidized bed reactor at a pilot scale. The effect of pyrolysis parameters such as temperature, biomass particle size, and carrier gas flow rate on the production of bio-oil, char, and syngas was investigated. The maximum bio-oil yield of 44.6 wt.% was achieved at a pyrolysis temperature of 500℃. The physicochemical properties of bio-oil were determined, and the heating value was found to be 18.5 MJ/kg. Furthermore, the chemical composition of maize straw bio-oil was analyzed by GC-MS and FTIR. The compounds such as phenol (22.83%), carboxylic acids (27.36%), ketone (19.14%) alcohols (2.09%), esters, furfural, hydrocarbon and aromatic compounds, etc. were identified in the bio-oil. The cost analysis of the developed system showed that the cost of production of bio-oil from maize straw was 0.47 US$/L and the calculated payback period was 1.47 year.

“…According to Şensöz et al (2006) and Haykiri-Acma (2006), there is a significant effect of particle size on the char, oil and gas yield in the pyrolysis of bagasse, hazelnut shell and rice husk. In addition, based on the research by Demirbas (2004) and Madhu et al (2015) the moisture content of the feedstock will affect the efficiency of the thermal pyrolysis reaction and hence the quality of the bio-oil produced. If it is too high, the moisture content in the bio-oil will also be high, and that not only will decrease the caloric value, but also will corrode the piping and other material system related to the facilities.…”

Pyrolysis process offers solution to utilise huge quantity of biomass to produce fuel for energy needs. This paper describes the development of a new model for waste cotton shell pyrolysis. This model calculates the minimum fluidisation velocity for various sand particles for better fluidisation. Cotton shell wastes were subjected to pyrolysis at atmospheric pressure under inert gas atmosphere in a fluidised bed setup to determine the effect of operation parameters. The sand particle size 0.71 mm offered better fluidisation and is more economical as it utilises low hydrogen flow rate. The maximum yield of bio-oil 51 wt% can be obtained under the operation parameters of 450ºC pyrolysis temperature, 1 mm particle size at sweep gas flow rate of 1.75 m 3 /h. In addition, the characterisation study of the bio-oil has been done for its physical and chemical analysis with gas chromatography mass spectroscopy. The elements and its derivatives found in the GC-MS analysis are used as a feed stock for chemical industries.
