Biomassza-alapú energiák innovációjának genomikai megközelítései AgEcon
Marothy, Gergely; Kondorosi, Eva; Bíró, Tibor.
A genomika valódi eszköz a biomassza-alapú energiák innovatív kutatása területén, egyes részterületei (metagenomika, transzkriptomika) ténylegesen alkalmazhatók a biomassza-alapanyag optimalizálása során, illetve a biomassza-konverzió hatékonyságának javításában, ezáltal a megújuló energiatípusok előállítási költségeinek csökkentésében. ------------------------------------------------ Genomics is a useful tool in innovative research into biomass energy. Certain fields of genomics (metagenomics, transcriptomics) have a practical application in biomass optimisation and in improving the efficiency of biomass, and can thus help reduce the costs of renewable energy production.

Energetic potential of bamboo culms for industrial and domestic use in Southern Brazil Ciência Rural
Balduino Junior,Ailton Leonel; Balduino,Thalles Yurgen; Friederichs,Gustavo; Cunha,Alexsandro Bayestorff da; Brand,Martha Andreia.
ABSTRACT: This study aimed to determine the energetic quality of the Bambusa vulgaris culms for combustion (in natura) and as a charcoal. Five individuals (culms) of Bambusa vulgaris of 3 years of age were analyzed, gathered in the city of Florianópolis, Santa Catarina. In the in natura culms it was determined the moisture content freshly gathered (39%); basic density (0.624gcm-3); the chemical composition (total extractive content (16.26%) and lignin content (25.76%)); the proximate chemical composition (volatiles content (82.25%); fixed carbon content (15.26%) and ash (2.49%)) and gross calorific value (4571kcalkg-1). In the charcoal, produced in the laboratory, the determined properties were the gravimetric yield (36.40%);the apparent density...

Energy balance and CO2 emission in mechanized biomass harvesting in pine stands under thinning Anais da ABC (AABC)
RODRIGUES,CARLA K.; LOPES,EDUARDO S.; SILVA,DIMAS A.; FIGUEIREDO FILHO,AFONSO; PELISSARI,ALLAN L..
Abstract: Biomass is an important component of the Brazilian energy matrix, with a potential contribution of co-products from thinned forests. The aim of this work was to evaluate the energy balance and CO2 potential emission in mechanized biomass harvesting operations in Pinus taeda stands at 9 and 10 years-old and under thinning, searching to support the use of co-product biomass from thinning as a renewable energy source. Thinning was carried out through cut-to-length harvesting method, in which large logs for sawmill and small logs for energy were produced. In addition, tops, needles, barks, and branches were considered as co-products. The balance between consumed energy and emitted CO2 by machines for thinning in relationship to the energy and CO2 in...

Wood and charcoal quality from planted forest in Minas Gerais State, Brazil PFB - Pesquisa Florestal Brasileira
Protásio, Thiago de Paula; Goulart, Selma Lopes; Neves, Thiago Andrade; Trugilho, Paulo Fernando; Ramalho, Fernanda Maria Guedes; Queiroz, Lívia Mara Rodrigues de Souza Brites.
The objective of this study was to evaluate the wood and charcoal quality of young Eucalyptus spp. trees, and to verify the influence of age and clone on the energy performance of these fuels. It was sampled the clones 1277 and 0321 of Eucalyptus spp. in two ages (46 and 58 months). The characteristics determined in the wood were: chemical molecular and elementary, basic density, carbon stocks and lignin by volume, the energy density and heating values (higher and lower). The charcoal was produced in an electric furnace (muffle) with the final temperature of 450 °C. It was conducted the mass balance and carbonization energy, beyond the immediate evaluation of the chemical composition, apparent density and calorific value of charcoal. The clone 1277, at the...
