“…The results revealed that the maize straw gave the maximum bio-oil yield of 46.0%, higher than the wheat and cotton stalk at pyrolysis temperature of 500℃. Therefore, it is observed that the results of present study in terms of bio-oil quality and quantity is found better than the Ali et al [40], Sahoo et al [11] and nearly similar with Fu et al [60]. The cost economics is the most vital factor, which can help to extend the research work of fast pyrolysis of agricultural residue from laboratory to commercial scale.…”

“…The volatile matter and ash content of biomass feedstocks has the major effect on the pyrolysis product distribution. Sahoo et al [11] performed the fast pyrolysis of wheat straw at a laboratory scale i.e. 5 g/h in a fixed bed reactor.…”

“…However, pyrolysis requires medium temperature (400-600℃) and dry-loose biomass can be treated. For the conversion of agricultural biomass into fuel pyrolysis process is found most easy, efficient and economical than the other thermo-conversion methods [11]. However, the yield of these products may depend upon the process conditions such as temperature, biomass, and residence time.…”

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.

“…Although they are mostly found in lower concentrations, it is possible to produce bio-oils with somewhat higher amounts of alcohol or sugar. For instance, bio-oil produced from corrugated cardboard (47% yield) achieved 20% levoglucosan content [53], while there are also reports of alcohol levels around 40% (50% bio-oil yield) [122] and 30% (33% bio-oil yield) [91].…”

Bio-Oil: The Next-Generation Source of Chemicals

Bio-oil, although rich in chemical species, is primarily used as fuel oil, due to its greater calorific power when compared to the biomass from which it is made. The incomplete understanding of how to explore its chemical potential as a source of value-added chemicals and, therefore, a supply of intermediary chemical species is due to the diverse composition of bio-oil. Being biomass-based, making it subject to composition changes, bio-oil is obtained via different processes, the two most common being fast pyrolysis and hydrothermal liquefaction. Different methods result in different bio-oil compositions even from the same original biomass. Understanding which biomass source and process results in a particular chemical makeup is of interest to those concerned with the refinement or direct application in chemical reactions of bio-oil. This paper presents a summary of published bio-oil production methods, origin biomass, and the resulting composition.

“…Sahoo et al [66] determined the dependence of the composition and heat of combustion of pyrolysis gas on the type of biomass in use. The research findings suggest that the heat of combustion of syngas obtained from the pyrolysis of biomass with a high content of cellulose and hemicellulose is lower than that from the pyrolysis of lignin-rich biomass.…”

The development of the world economy goes hand in hand with increased energy consumption and global warming caused by greenhouse gases. These issues can be tackled by implementing promising technologies of power generation. They differ from the known ones in that new energy resources are involved, e.g., mixtures of various types of biomass, provided that hazardous gas emissions during the production process are minimized. The development of high-potential energy-efficient and environmentally friendly technologies which use biofuel in the energy industry requires scientific evidence for the mechanisms, conditions, and characteristics of physical and chemical processes during pyrolysis and gasification of biomass, including its multicomponent types. This article analyzes the world technologies and research findings in the field of biomass pyrolysis and gasification. The effect of a group of factors on the intensity and completeness of gasification and pyrolysis of biofuel compositions has been determined. These factors include the size, shape, and surface structure of biomass particles; component composition and properties of fuel mixtures; mechanism and intensity of heat supply; and the temperature field in the reactor filled with solid and gaseous products. The most effective values of these characteristics have been established.
