Experimental investigation of pyrolysis process of woody biomass mixture

Experimental investigation of heating values and chemical compositions of selected fuel woods as bio-fuel sources in developing countries

“…Adansonia digitata (Ad), Terminalia ivorensis(Ti), Khaya ivorensis (Ki), Mansonia altissima(Ma)and Okoubaka aubrevillei(Oa). This study's low sulfur content (0.05 %), which is within the same range of values as that reported by Oyebanji et al [14], Chukwuneke et al [15], and Okekunle et al [16], implies a low pollutant influence on the environment. Lower pour points indicate the temperature at which a bio-oil ceases to flow due to the development of wax crystals that enhance its viscosity, but lower flash points indicate good flammability and volatility of the oil.…”

“…The data study revealed an average of 44.3 percent liquids, 30.6 percent biochar, and 25.1 percent gas, with acetic acid, formic acid, furfural, and lactic acid being the most prevalent liquid products. Using a fixed-bed tube reactor, Demirbas [15] examined the effects of pyrolysis on The prime objectives of this study are to: (i) determine experimentally the higher heating values (HHVs) of five selected fuel woods (Adansonia digitata, Terminalia ivorensis, Khaya ivorensis, Mansonia altissima, Okoubaka aubrevillei) obtained from South Western Nigeria for effective utilization as bio-fuel and (ii) investigate the chemical composition of the pyrolysis products (bio oils) of the selected fuel wood samples using a gas chromatography-mass spectrometry (GC-MS) analyzer as potential substitute for fossil fuel.. In this study, pyrolysis method is used considering its superior ability to decompose biomass at temperatures between 300 • C and 600 • C and in the absence of an oxygen-rich atmosphere.…”

Activated charcoal production from tree pruning in the Amazon region of Brazil for the treatment of gray water

“…Through the analysis of the TG/DTG curves, it is possible to verify the reduction of humidity, which graphically demonstrated by the appearance of an event in the tree pruning sample, starting at 40 ° C and finishing at around 160 °C, corresponding to the loss of water. This event is well above the boiling point of water, and according to some researchers, this is due to the fact that materials with higher ash content in their chemical composition have the maximum release of volatiles at higher temperatures (Kosanić et al, 2014;Neves et al, 2014). The tree pruning sample contains many inorganic materials (sand, silt, soil), favoring the dilution of the organic material which may cause a delay in heat transfer into the particles and hence the diffusion of volatiles during pyrolysis of biomass (Bridgwater, 2012;Pedroza et al, 2017).…”
