| Production of biomass from native prairie species offers the opportunity to produce energy and chemicals while providing substantial ecological services in the Northern Great Plains. This paper analyzes the application of rapid pyrolysis to produce bio-oil, which has the potential for use as a low-grade fuel oil or as a source for extraction of valuable chemicals. Yields of bio-oil, the quantities of extractable chemicals, and chemical prices drive the economics of this concept, which has a more extensive track record utilizing wood chips. A spreadsheet model was developed to determine gross margins available to defray costs to extract and refine such chemical products as hydroxyacetaldehyde, phenol, formic acid, acetic acid and various resins.... |

| O mundo busca fontes alternativas de energia, bem como aproveitamento de resíduos industriais considerados poluentes. Este trabalho avaliou a utilização da massa seca da parte aérea de sorgo biomassa e de capim elefante na forma in natura e acrescidas de óleos residuais (glicerina e bio-óleo) para geração de energia. Para tanto, foi implantado um experimento no delineamento inteiramente ao acaso com três repetições, composto por 10 tratamentos: sorgo biomassa, capim elefante e as misturas destas biomassas com duas concentrações de bio-óleo e duas de glicerina. Foi avaliada a umidade, voláteis, cinzas, carbono fixo e poder calorífico superior (PCS). Os dados foram submetidos à análise de variância e as médias dos tratamentos foram agrupadas pelo teste de... |

| Thermochemical conversion of lignocellulosic biomass via fast-pyrolysis technique has become an interesting alternative to produce valuable bio-based products, such as the bio-oil. This alternative, for instance, can increase even more the profitability of such well-consolidated pulp and paper industries by turning it into more energetically self-sufficient processo Besides bio-oil, the fast-pyrolysis process results in many byproducts with high economic and environmental benefits. Biochar is one of these byproducts, and it can be activated by physical and chemical methods to use for water treatment and for environmental remediation. This study investigates the activation of biochar obtained from the fast-pyrolysis of wood biomass. The biochar was... |
