“…Unfortunately, in 2014/2015, low rainfall affected energy production, leading to the current energy crisis. Given this environmental crisis, lignocellulosic materials have become a potential alternative as energy source and inputs to human activities (Dhillon & Wuehlisch, 2013;Rodrigues, 2011). Furthermore, residues from the biomass must have proper destination, in order to prevent environmental damage due to the unbalance caused by inappropriate disposal.…”

Characterization of biomasses from the north and northeast regions of Brazil for processes in biorefineries

In search for renewable energy sources, the Brazilian residual biomasses stand out due to their favorable physical and chemical properties, low cost, and their being less pollutant. Therefore, they are likely to be used in biorefineries in the production of chemical inputs to substitute fossil fuels. This substitution is possible due to the high contents of carbohydrates (>40%), low contents of extractives (<20%), ashes (<8%) and moisture (<8%) found in these residual biomasses. High calorific values of all residues also offer them the chance to be used in combustion. A principal components analysis (PCA) was performed for better understanding of the samples and their hysic-chemical properties. Thus, this study aimed to characterize biomasses from the north (babassu residues, such as mesocarp and endocarp; pequi and Brazil nut) and northeast (agave and coconut) regions of Brazil, in order to contribute to the preservation of the environment and strengthen the economy of the region.Keywords: bioproducts; biorefinery; hysic-chemical properties; lignocellulosic residues.Practical Application: The Production of Sustainable Biofuels from the Residues and Wastes of Brazil principally of north of the country with technologies to help reduce the need for fossil diesel imports, improving the security of energy supply. Therefore rapid analytical methods can be used to analysis biomass and waste feedstocks pointing out the more promising candidates.

Fuel, Elsevier, 2013, 108, pp.812-823. 10.1016/j.fuel.2013 The gasification reactivity of high-heating-rate chars in single and mixed atmospheres of H 2 O and CO 2 C. Guizani ⇑ , F.J. Escudero Sanz, S. Salvador t r a c tGasification reactivity of high heating rate chars (HHR chars) in steam, carbon dioxide and their mix tures was investigated in a new macro TG experimental device. The higher reactivity of the HHR chars was highlighted by a comparison with reference chars prepared at a low heating rate (LHR chars). It was found that the char reactivity in a mixed atmosphere of steam and carbon dioxide can be expressed as the sum of the individual reactivities obtained in single atmosphere gasification experiments. This result was not dependent on the pyrolysis heating rate. In addition, gas alternation gasification experi ments for both HHR chars and LHR chars showed that gasifying the char with CO 2 up to 30% of con version does not affect its reactivity to H 2 O. Altogether, the results tend to indicate that the two reactant gases H 2 O and CO 2 react on separate active sites when mixed atmospheres are used, and that CO 2 does not affect the char structure to favor or inhibit the char H 2 O gasification reaction.

“…Biomass used for heat production costs between 26 and 156 €/MWh, which is competitive with fossil fuels, the price of which range from 52 to 234 €/MWh. In the UK, it is estimated that wood-based energy could reduce 2.7 Mt CO2 emissions/year if it displaces the energy from fuel oil for a furnance with a heat capacity of 30 MWh (Dhillon and von Wuelhlisch 2013).…”

This study was done to determine the effects of beech sawdust torrefaction on pellets obtained in the laboratory. Torrefied beech (Fagus sylvatica L.) sawdust was used to make pellets. This species was chosen based on the existence of a market for such micro-briquettes. Rigorous comparisons between torrefied and non-torrefied pellets were conducted. It was found that treating the sawdust had both beneficial and non-beneficial effects, but the total effect is positive. Economical elements were also considered, emphasizing the use of wood biomass as fuel. Theoretical and experimental aspects are taken into consideration, the experimental results being used to validate the theoretical model. The experiments performed demonstrate that heat treatment can add value if it meets certain parameters, such as a maximum temperature of 260 °C for 5 min. Heat treatment of beech sawdust in the form of pellets or briquettes was shown to be a simple, viable, effective treatment because the heating process improves the calorific value and other relevant properties of the torrefied sawdust.
