“…Moreover, in woody matrices, N-containing structures are more resistant to degradation with increasing temperature. According to Enders et al 2012 [ 18 ], N is highly retained in raw material wood-derived biochars, which is probably due to the formation of heterocyclic N such as pyridines and pyrroles.…”

“…The use of biochar produced from eucalyptus residues, which is an abundant material and is easy to acquire in several countries [ 18 ], can improve the destination of residues from the forestry industry. However, as reported, the temperature of pyrolysis influences the properties of biochar, which can influence the effectiveness of its use.…”

Impact of Pyrolysis Temperature on the Properties of Eucalyptus Wood-Derived Biochar

et al. 2020

Pyrolysis conditions directly influence biochar properties and, consequently, influence the potential use of biochar. In this study, we evaluated the effects of different pyrolysis temperatures (450, 550, 650, 750, 850, and 950 °C) on the hydrogen potential, electrical conductivity, ash content, yield, volatile matter content, elemental analysis, Fourier-transform infrared spectroscopy results, X-ray diffraction results, scanning electron microscopy results, specific surface area, and micropore volume of eucalyptus wood-derived biochar. The degree of linear association between pyrolysis temperatures and biochar properties was examined using the Pearson correlation coefficient. The results showed a positive correlation of the pyrolysis temperature with the hydrogen potential value, electrical conductivity, and elemental carbon. There was a negative correlation of the pyrolysis temperature with the yield, volatile matter content, elemental oxygen, elemental hydrogen, surface area, aromaticity, hydrophilicity, and polarity indexes. The Fourier-transform infrared spectroscopy data indicated an increase in aromaticity and a decrease in the polarity of high-temperature biochar. The increased pyrolysis temperature caused the loss of cellulose and crystalline mineral components, as indicated by X-ray diffraction analysis and scanning electron microscopy images. These results indicated that changing the pyrolysis temperature enables the production of biochar from the same raw material with a wide range of physicochemical properties, which allows its use in various types of agricultural and environmental activities.

“…The assessment of each mixture strictly followed the mass ratio of the three components of the ternary mixture. Literature data were used to calculate the environmental impacts for blends in categories of climate change: global warming potential (GWP; in kg CO 2 eq), acidification (in kg SO 2 eq), eutrophication (in kg PO 4 eq), and human toxicity (in kg DB eq, with DB meaning dichlorobenzene), with the functional unit of 1 kg fuel. Impacts of corn ethanol and municipal solid waste and eucalyptus BO are included in the range for more accurate comparison of systems (Tab.…”

Ternary Blends of Renewable Fast Pyrolysis Bio‐Oil, Advanced Bioethanol, and Marine Gasoil as Potential Marine Biofuel

2020

An alternative for reducing emissions from marine fuel is to blend bio-oil from lignocellulose non-edible feedstocks to diesel fossil fuels. Phase diagrams of the ternary systems were built to represent the transition from heterogeneous regions to homogeneous regions. Four homogeneous blends of bio-oil of eucalyptus-bioethanol-marine gasoil were experimentally characterized with respect to the most important fuel parameters for marine engines: water content, flash point, low heating value, viscosity, and acidity. Blends with closer properties to marine gasoil replacement, lower costs, and environmental impacts should be tested for large engines.

“…The contribution of fossil fuels to the increasing world burden of greenhouse gases has encouraged investigation of renewable sources as providers of liquid fuel (biofuel). Wood, consisting mainly of lignin, cellulose and hemicellulose, is such a source and biofuel production by wood pyrolysis is a relatively economic and environmentally friendly method of utilizing wood as an energy source (Heidari et al, 2019). However, the characteristics of wood are highly variable and it would be useful to have a method of rapidly assessing the relative biofuel yield and yields of major compounds (biofuel quality) of different wood species as a function of variables such as temperature.…”

Py-GC/MS analysis of six different species of fast growing Macaranga wood has been studied. Flash pyrolysis was conducted at different temperatures (250-850 oC) under a flow of helium followed by GC/MS analysis of the products. The total pyrolysis yields of the six different species of Macaranga were mostly between 40 and 90% within the range of pyrolysis temperature applied. Pyrolysis of the woody biomass produced compounds which are mostly derived from thermal degradation or volatilization of lignin and cellulose/hemicellulose, the original major constituents of the biomass. The Py-GC/MS technique indicated that M. gigantea was the most potential species for biofuel production and the optimum pyrolysis temperature to produce high yields of bio-oil was 450 oC.
