“…Machado et al [200] noted that both the bagasse and leaves of sugarcane have potential to be used as substrates to obtain high value-added products from their cellulosic fractions, such as organic acids, biofuels, and biopolymers. Bispo et al [203] produced bio-oil through pyrolysis of sugarcane straw. Simo et al [204] investigated anaerobic digestion of sugarcane bagasse to produce biogas while Patil and Deshannavar [205] investigated the potential of using sugarcane leaves for producing briquettes.…”

An Assessment of Potential Resources for Biomass Energy in Nigeria

Nigeria is a developing country with an insufficient supply of energy to meet the continuously growing demand. However, there are several biomass resources available within the country. This paper presents a desk review, which investigates the potential resources for biomass energy generation within the country. Energy policies to aid biomass use as an energy source within the country were also reviewed. Biomass resources identified within Nigeria include forest residues, agricultural residues, human and animal wastes, aquatic biomass, and energy crops. However, several of the resources, particularly agricultural residues, have competing uses, such as livestock feed and soil rejuvenation. An estimation of the technical energy potential of the biomass resources revealed that about 2.33 EJ could be generated from the available resources in Nigeria. Agricultural residues have an energy potential of about 1.09 EJ, with cassava, maize, oil palm, plantain, rice, and sorghum being the major contributors. Animal wastes, municipal solid waste, and forest residues have energy potentials of 0.65, 0.11, and 0.05 EJ, respectively. The potentials of wood fuel and charcoal are 0.38 and 0.05 EJ, respectively. The study found that despite the available potential and existing policies, not much has been done in the implementation of large-scale bioenergy within the country. However, there has been laboratory and research-scale investigations. The review suggests that more policies and stronger enforcement will aid bioenergy development within the country. From the review, it has been suggested that the agricultural sector needs to be developed to generate more biomass resources. More research, development, and implementation have to be carried out on biomass resources and bioenergy generation processes. The production of non-edible energy crops in marginal lands should also be considered prime to the development of bioenergy within the country.

“…It is found that the phenols are major in both area (approximately 80%) and in number (44.90% of the identified compounds). This fact occurs due to the high content of lignin present in the biomass used (MIGLIORINI et al, 2013;ZHANG et al, 2013;BISPO et al, 2016). According to Souza, et al (2012), woody materials such as peach stone are rich in lignin and cellulose and when carbonized, they are thermally degraded in ketones, alcohols, furan derivatives and phenolic compounds.…”

The peach stone is considered an agroindustrial residue originating from the industrial process of peach in halves in syrup. It does not have an adequate destination, its final disposal is incorrect and may cause contamination in the environmental compartments. In this way, the burning of this raw material as biomass enables its reuse, besides adding value to the residue. Among the processes used for the application of this residue is the carbonization process, which allows to obtain co-products with higher added value, such as pyroligneous liquid, which represents a fraction of organic compounds condensed from the smoke emitted during carbonization. The quality of the liquid depends on the process conditions and the biomass used. Therefore, the objective of this study was to characterize the sample of pyrolignous liquid obtained from the carbonization of the peach stone, on an industrial scale, qualitative and semi quantitative. Preliminary characterization (pH, conductivity, color, density and contents of tar, organic matter and acidity) and a chemical characterization by gas chromatography coupled to mass spectrometry (GC-MS) were performed. The liquid presented satisfactory results for the physico-chemical evaluations. Regarding the qualitative determination, it was possible to identify 49 compounds. Highlighting the phenols, with 44.90% of the number of compounds, mainly methoxyphenols. These are compounds with significant added value and industrial importance, indicating their use as raw material in the production of polymer resins, among other purposes.

“…From this last step, the ideal pyrolysis temperature was determined to obtain better bio-oil yields. Therefore, the maximum temperature selected to carry out pyrolysis in this study was set at 700°C, aligned with findings in the literature on green coconut fiber pyrolysis (Almeida et al 2013;Bispo et al, 2016).…”

The great potential of bio-products generated from agro-industrial residues from the biomass processing, as is the case with the green coconut fibers (Cocos nucifera L. var. dwarf), makes Brazil stand out in the field of transformation of these residues, mainly due to its high biodiversity and favorable climatic conditions. In this work, residual green coconut fibers were used in the production of bio-oil by pyrolysis. The bio-oil was fractionated using preparative liquid chromatography (PLC) in silica using solvents of different polarities: hexane, hexane/toluene, toluene/dichloromethane, dichloromethane/acetone, and methanol. Bio-oil and its fractions were analyzed by gas chromatograph /quadrupole mass spectrometer (GC/qMS). The concentration of each compound was carried out by multiplying the percentage area of the corresponding peak by the mass yield of the respective fraction. PLCof bio-oil increased the number of compounds identified by about 170% compared to the original bio-oil (non-fractionated), besides allowing the isolation of nonpolar compounds (mostly hydrocarbons) from polar compounds (mainly phenols, aldehydes, and ketones). Anotheradvantage of PLC was the increase in the number of hydrocarbons identified in the fractions, as opposed to the crude bio-oil analysis. Among the major compounds, phenols can be highlighted, besides furfural derivatives and hydrocarbons, which indicates the potential use of bio-oil mainly for industrial purposes.
