13. Implementation of a Photovoltaic Panel to Supply Electric Cars Energy Demands
ABSTRACT The gradual shifting of the energy matrix to renewable sources is one of the main global strategies for sustainable development. According to studies, the use of electric energy by automobiles would lead to a reduction in gasoline consumption of 40.7% in 2031, accompanied by an increase in electricity consumption of 42.1% in relation to official pro

14. Fine and Coarse Aerosol at Rio de Janeiro prior to the Olympic Games: Chemical Composition and Source Apportionment
During the period from June 2012 to June 2013, the concentrations and chemical composition of PM2.5 and PM2.5-10 (particulate matter with a diameter of 2.5 μm or less and between 2.5 and 10 μm, respectively) were monitored at four sampling points in the Rio de Janeiro metropolitan area, and two of the points were in close proximity to the 2016 Olympic Game

15. CASOS INVESTIGATIVOS PARA A PROMOÇÃO DA CSCL NO ENSINO SUPERIOR DE QUÍMICA
This paper addresses a didactic activity based on computer-supported collaborative learning (CSCL) principles applied to a scientific communication course offered to undergraduate chemistry students. We investigated the dynamics of interactions among the students within the groups focusing on skills of conversation described in the Collaborative Learning Mod

16. Changes in the microbial community during bioremediation of gasoline-contaminated soil
Abstract We aimed to verify the changes in the microbial community during bioremediation of gasoline-contaminated soil. Microbial inoculants were produced from successive additions of gasoline to municipal solid waste compost (MSWC) previously fertilized with nitrogen-phosphorous. To obtain Inoculant A, fertilized MSWC was amended with gasoline every 3 days

17. Genetic Engineering In BioButanol Production And Tolerance
ABSTRACT The growing need to address current energy and environmental problems has sparked an interest in developing improved biological methods to produce liquid fuels from renewable sources. Higher-chain alcohols possess chemical properties that are more similar to gasoline. Ethanol and butanol are two products which are used as biofuel. Butanol production

18. THE BRAZILIAN EXPERIENCE WITH ETHANOL FUEL: ASPECTS OF PRODUCTION, USE, QUALITY AND DISTRIBUTION LOGISTICS
Abstract The reduction in the availability of fossil fuel increased the search for alternative fuel sources (for example, ethanol). In the Brazilian market, light duty vehicles can be fueled with gasohol (18 up to 27.5 %v/v of anhydrous ethanol in gasoline) and/or hydrous ethanol. To minimize the risk of water-induced phase separation of gasoline-ethanol ble

19. BIODEGRADATION OF EFFLUENT CONTAMINATED WITH DIESEL OIL AND GASOLINE USING CHITOSAN AS A NATURAL COAGULANT IN A CONTINUOUS PROCESS
Abstract This study evaluated the effects of aeration (constant aeration, intermittent aeration and a lack of aeration) and hydraulic retention time (HRT) (2, 3 and 4 days) on a continuous process with cell recycling, using chitosan as a natural coagulant for the sedimentation of a C1 mixed culture. This culture was used for the biodegradation of hydrocarbon

20. Emissions of Criteria and Non-Criteria Pollutants by a Flex-Fuel Motorcycle
While criteria pollutants have established emission limits for motorcycles in Brazil, aldehydes limits have not been established and conclusive studies have not been found in the existing literature, despite the growing number of motorcycles using flex fuel in Brazil. This work presents results for the emissions of criteria pollutants, such as carbon monoxid

21. Gas-Phase Polycyclic Aromatic Hydrocarbons in the Parking Lot Impacted by Light-Duty Vehicles Burning Gasoline and Ethanol Blends
In order to study the emission of vapor-phase polycyclic aromatic hydrocarbons (PAHs) by light-duty vehicles burning gasoline and ethanol blends, air samplings were performed at a parking lot in Londrina, PR, Brazil. The samples were obtained during the summer and winter 2012. The semi-volatile PAHs were collected using a cartridge packed with XAD-2 resin, e

22. MODELING STYRENE HYDROGENATION KINETICS USING PALLADIUM CATALYSTS
Abstract The high octane number of pyrolysis gasoline (PYGAS) explains its insertion in the gasoline pool. However, its use is troublesome due to the presence of gum-forming chemicals which, in turn, can be removed via hydrogenation. The use of Langmuir-Hinshelwood kinetic models was evaluated for hydrogenation of styrene, a typical gum monomer, using Pd/9%N

23. Oxidative Desulfurization of Gasoline by Ionic Liquids Coupled with Extraction by Organic Solvents
In this work, desulfurization of real fluidized catalytic cracking (FCC) gasoline was investigated in dual steps; first in oxidative desulfurization (ODS) using imidazolium and pyrrolidonium based Brønsted acidic ionic liquids (ILs) as solvent and catalyst and hydrogen peroxide as oxidant. In second step, extractive desulfurization took place using organic

24. Experimentally Validated Combustion and Piston Fatigue Life Evaluation Procedures for the Bi-Fuel Engines, Using an Integral-Type Fatigue Criterion
Abstract A relatively complete procedure for high cycle fatigue life assessment of the engine components is outlined in the present paper. The piston is examined as a typical component of the engine. In this regard, combustion process and transient heat transfer simulations, determination of the instantaneous variations of the pressure and temperature in the
