1. INDUSTRIAL PLANT FOR PRODUCTION OF Spirulina sp. LEB 18
ABSTRACT Biorefineries based on microalgae produce biofuels and co-products with added value. Microalgae mainly require water, carbon dioxide and sunlight for growth. The bioproducts of the cultivation of these microorganisms can be fully used in a microalgae photobiorefinery. The objective of this work was to study the behavior of physico-chemical variables

2. A GENERIC TACTICAL PLANNING MODEL TO SUPPLY A BIOREFINERY WITH BIOMASS
ABSTRACT The supply chains which bring biomass to biorefineries play a critical role in biofuel production. Optimization models can help decision makers to design more efficient chains and minimize the cost of biomass delivered to the refineries. This article based on a French national research project on biomass logistics considers one refinery, able to pro

3. Characterization of biomasses from the north and northeast regions of Brazil for processes in biorefineries
Abstract 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 con

4. OPTIMIZATION OF PRODUCTION OF 5-HYDROXYMETHYLFURFURAL FROM GLUCOSE IN A WATER: ACETONE BIPHASIC SYSTEM
Abstract5-Hydroxymethylfurfural (HMF) is considered to be an important building block for biorefineries and has a high potential for the production of chemicals and fuels. Production of HMF from glucose was studied using phosphoric acid as catalyst, in a water:acetone system with volume ratio of 1:2 and NaCl. An experimental design was applied to examine the

5. Catalytic Transformations of Ethanol for Biorefineries
Brazil e Estados Unidos são os maiores produtores mundiais de bioetanol e a principal aplicação desse álcool é como combustível. Como o etanol brasileiro é o mais barato do mundo, há um interesse crescente no seu uso como precursor nas biorefinarias para síntese de moléculas maiores. O bioetanol pode ser usado na produção direta de olefinas como

6. Proposta de um modelo conceitual de biorrefinaria com estrutura descentralizada
A busca por segurança energética tem feito com que a maioria dos países empenhe-se na busca por fontes alternativas de energia, procurando mitigar problemas econômicos, sociais e ambientais. Espera-se que a biomassa, disponível de forma geograficamente dispersa, venha a tornar-se um dos principais recursos renováveis na produção de alimentos, materia

7. Use of a biofuel obtained from the fast pyrolysis of sugarcane trash in an Otto engine / Uso de biocombustivel da pirolise rapida da palha de cana em um motor de ciclo Otto
In September 2002 the state of São Paulo promulgated the Law Nº 11241 by which was codified the gradual elimination of fire as a method to remove trash from the sugar-cane fields before harvestig. Large amounts of sugar-cane trash with an important energy potential will be available as a result of this law. New technologies to harvest and process this biom
