2. Aplicação de processo adsortivo para dessulfurização de combustíveis utilizando fibra de coco como adsorvente
RESUMO A presença de compostos orgânicos contendo enxofre nos combustíveis é um dos contribuintes da poluição atmosférica, pois quando entram em combustão nos motores, emitem poluentes derivados do enxofre, como os óxidos (SOx), que afetam negativamente a saúde humana e o meio ambiente. A remoção do excesso de enxofre presente na gasolina pode se

3. Evaluating the Electrochemical Characteristics of Babassu Coconut Mesocarp Ethanol Produced to Be Used in Fuel Cells
The aim of the present study is to assess the potential of ethanol deriving from the mesocarp of babassu coconut to be used in fuel cells. Babassu ethanol was generated through hydrolysis and fermentation processes. The Pt, PtRh and PtRu electrodes were prepared in carbon Vulcan XC72R through the reduction method and applied as electrocatalysts in ethanol ox

4. 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

5. Obtention and characterization of coconut babassu derivatives
Babassu (Orbignya sp.) is a palm with extraordinary socioeconomic and ecologic importance found in humid tropical areas in Brazil, especially in frequently burned and degraded landscapes. There are several uses for babassu oil; however, its potential for providing other industrial products remains unexploited, due to the lack of scale and production structur

6. Avaliação do processo adsortivo utilizando mesocarpo de coco verde para remoção do corante cinza reativo BF-2R
This work used green coconut mesocarp as a bioadsorbent to remove Reactive Gray BF-2R dye. A 2³ factorial design was used to evaluate the influence of the variables adsorbent mass, particle size and stirring speed on the adsorptive process. Kinetic and adsorption equilibrium studies were performed. Results showed that the kinetic equilibrium was reached aft

7. MESOCARP OF GREEN COCONUT (Cocos nucifera) AND TATAJUBA SAWDUST (Bagassa guianensis Aubl) AS ADSORBENTS IN AQUEOUS / MESOCARPO DE COCO VERDE (Cocos nucífera) E PÓ DE SERRAGEM DA TATAJUBA (Bagassa Guianensis Aubl) COMO ADSORVENTES EM MEIO AQUOSO
Neste trabalho, a eficiência de dois resíduos agrícolas, serragem de madeira e mesocarpo de coco verde, como adsorventes para íons de metais (Ni2+, Cu2+) e dois corantes têxteis (vermelho e violeta brilhante Remazol) foi investigada. Os teores de umidade, carboidratos, proteínas, gorduras, cinzas e fibras de ambas as matrizes naturais foram medidos. Os

8. MESOCARPO DO COCO VERDE (Cocos nucífera) COMO ADSORVENTE PARA OS CORANTES: TURQUESA REMAZOL E AZUL REMAZOL / MESOCARP GREEN COCONUT (Cocos nucifera) AS ADSORBENT FOR COLOURS: Turquoise and blue Remazol
In this work the green coconut mesocarp was used as adsorbent towards two textile dyes: Turquoise Remazol and Blue Remazol. The adsorbent was triturated, washed several times with water for extraction of soluble matter, dried in oven and sieved to obtain particle size between 0.088 and 0.177 mm. Determinations of C/H/N content were performed and the obtained

9. Removal of cyanobacteria toxins from drinking water by adsorption on activated carbon fibers
Natural fibers from macadamia nut shell, dried coconut shell endocarp, unripe coconut mesocarp, sugarcane bagasse and pine wood residue were used to prepare activated carbon fibers (ACF) with potential application for removing microcystins. The ACF from pine wood and sugar cane bagasse were used to remove [D-Leucine¹]MCYST-LR from water. After 10 minutes of

10. Desempenho de biomassas na adsorção de hidrocarbonetos leves em efluentes aquosos
Removal of hydrocarbons from aqueous effluents using biosorbents was investigated. The effluent was simulated by a dispersion of gasoline (simple hydrocarbons) in water. Corn-cob, wood powder, coconut mesocarp and sugar-cane bagasse were used as adsorbents and their performance verified by means of batch experiments performed in an agitated vessel. The influ

11. AvaliaÃÃo do processo de adsorÃÃo da microcistina-LR por carvÃo ativado
Because of the increase of the number of reports of acute and chronic intoxications, as much in animals as in human beings, for toxins produced by cyanobacteria in the water, there is already a great concern on the part of the companies responsible for the treatment and distribution of drinking water. The application of adsorption process for coal activated

12. AvaliaÃÃo do processo de remoÃÃo de ferro em Ãgua de origem subterrÃnea por adsorÃÃo com materiais naturais
A presenÃa de metais em Ãguas de abastecimento da grande Recife foi evidenciada a partir de uma avaliaÃÃo preliminar. Foram encontradas concentraÃÃes de ferro superiores ao permitido pela legislaÃÃo (0,30 mg.L-1 segundo a portaria N 518 do MS). A presenÃa deste metal à funÃÃo da origem da Ãgua. Podendo ser proveniente da dissoluÃÃo de rochas
