“…The highest average mass losses occurred in the ranges of 300-400°C and 400-500°C, corresponding to a variation of 37.94 and 6.29% in wood weight, respectively, totaling 44.23%. This finding can be explained by the fact that the peak mass loss for cellulose occurs at a higher temperature than that of hemicelluloses, as cellulose requires a great amount of energy for chain depolymerization and degradation of monomers (Liao, 2003;Fernandez et al, 2019).…”

“…Regarding the potential for charcoal production, the results of the present study demonstrate the low contribution of cellulose to charcoal yield. Moreover, other studies have shown that the residual mass of cellulose ranges from 5 to 10wt.% at 450°C (Yang et al, 2007;Shen and Bridgwater, 2010;Fernandez et al, 2019). Lignin does not have a specific degradation peak, because its thermal decomposition occurs over a wide range of temperatures, that is, its degradation occurs at a slow and steady rate.…”

“…The thermogravimetric analysis (TGA) accompanies the of the sample as a function of time, it being possible to determine the temperature when the thermal degradation starts and when it is most intense. Also provide the amount of residue is produced at a certain temperature, being of this important tool when you want to select species for energy purposes (Carneiro et al, 2013;Araújo et al, 2016;Azizi et al, 2017;Martinez et al, 2018;Fernandez et al, 2019).…”

Thermal profile of wood species from the brazilian semi-arid region submitted to pyrolysis. CERNE, v. 25, n. 1, p. 44-53, 2019. HIGHLIGHTS We analyzed native and endangered species of the Brazilian semi-arid region. The thermal profile of the species was questioned for energy generation. Mimosa tenuiflora and Poincianella pyramidalis were the most suitable wood species for sustainable charcoal production. The energy characteristics will allow the efficient management of the species in mixed plantations for this purpose.

The steel industry represents about 7% of the world’s anthropogenic CO2 emissions due to the high use of fossil fuels. The CO2-lean direct reduction of iron ore with hydrogen is considered to offer a high potential to reduce CO2 emissions, and this direct reduction of Fe2O3 powder is investigated in this research. The H2 reduction reaction kinetics and fluidization characteristics of fine and cohesive Fe2O3 particles were examined in a vibrated fluidized bed reactor. A smooth bubbling fluidization was achieved. An increase in external force due to vibration slightly increased the pressure drop. The minimum fluidization velocity was nearly independent of the operating temperature. The yield of the direct H2-driven reduction was examined and found to exceed 90%, with a maximum of 98% under the vibration of ~47 Hz with an amplitude of 0.6 mm, and operating temperatures close to 500 °C. Towards the future of direct steel ore reduction, cheap and “green” hydrogen sources need to be developed. H2 can be formed through various techniques with the catalytic decomposition of NH3 (and CH4), methanol and ethanol offering an important potential towards production cost, yield and environmental CO2 emission reductions.

“…At present, researchers have extracted bio-oil from microalgae (Brennan et al 2010), manure (Fini et al 2011), oil seeds (Kong et al 2019; Kong et al 2018; Kong et al 2017), short rotation forestry wood (Prayogo et al 2014; Van et al 2010), corn stover (Raouf et al 2010), rice husks (Zheng et al2010), and other materials ( Van et al 2010;Sanna et al 2011). Many innovative techniques for producing bio-oil from biomass have been developed, mostly including thermochemical techniques such as hydrolysis, pyrolysis and liquefaction (Fernandez et al 2019; Van et al 2008; Van et al 2006;Demirbas 2001;Önal et al 2011), with pyrolysis as the most widely used technology. In the absence of air, pyrolysis converts organic matter into a solid biochar, a condensable bio-oil and non-condensable small molecule gases (Goyal et al 2008; Akhtar et al 2010).…”

The "green" production of bitumen has raised increasing interest in recent years to reduce the environmental, energy and petro-based concerns. Bio-oil, prepared by biomass pyrolysis, can be used as substitute for petro-based bitumen in bitumen or bitumen-based coatings, for its similar properties of good adhesion and anti-corrosion characteristics. Although biomass is a renewable and widespread chemicals resource, its value-added utilization is still difficult. Several studies have qualitatively demonstrated the use of bio-bitumen in practical applications. The present study investigates the effects and properties and the incorporation of bio-bitumen shown to improve the performance of traditional petro-bitumen to some extent. Bio-bitumen was prepared from biomass pyrolysis oil and applied to self-adhesive and doped hot-melt sheets. Resulting
