1. 1H NMR and Chemometric Methods to Estimate the Octane Number in Brazilian C Gasolines
Brazilian gasoline type C can be purchased with octane number as the main difference. This quality parameter directly affects the price. Intermediate formulations may not be easily distinguished from conform samples due to similarity in visual appearance and physicochemical properties. The use of anhydrous ethanol as an additive also influences the octane va

2. Determination of Methanol in Gasoline and Ethanol Fuels by High-Performance Liquid Chromatography
Gasoline and ethanol fuels have been adulterated with methanol in Brazil. Methanol is not permitted in concentrations greater than 0.5 vol% due its toxicity but its lower price stimulates the adulteration. A new approach for quantitative analysis of methanol in gasoline and ethanol fuels is reported employing high-performance liquid chromatography coupled wi

5. Introdução de misturas de GNV e hidrogênio (Hidrano) em veículos convencionais no Brasil e seus impactos econômicos, ambientais e energéticos / Introduction of CNG and hydrogen (HCNG) for conventional vehicles and its economic, environmental and energy impacts
Several strategies have been proposed to introduce hydrogen in the economy specifically in the transport sector in order to reduce environmental impacts of conventional fuels. One of the strategies implies in adding hydrogen to compressed natural gas (HCNG), making use of the existing refueling stations and natural gas fleet. Thus the costs and time for the

6. Produção de cana-de-açúcar para obtenção de etanol hidratado no Rio Grande do Sul : uma análise utilizando dinâmica de sistemas
Brazilian use of sugar cane ethanol in its energy matrix has been gaining international recognition. With a growing fleet of flex fuel vehicles, Brazil has been building an each year greater demand for ethanol. Nevertheless, consumption levels throughout the country are not homogeneous. Far from sugar cane production centers and with one of the nations highe

7. Elasticidades de curto e longo prazos da demanda por Ãlcool hidratado no Brasil
Since March 2003, with the launch of flex fuel cars, consumption of hydrated alcohol again grows strongly in Brazil. The option of the consumer choice, holder of this technology, which allows the use of hydrated alcohol, gasoline or any mixture of proportion between the two in a single tank of fuel, leads to take as main variable the price of fuels (hydrated

8. O Etanol e a Gasolina sÃo Substitutos Perfeitos? / The Etanol and the Gasoline are Perfect Substitutes?
The relative domestic prices behavior for fuels (relationship among price of ethanol and gasoline) was analyzed accord to panel monthly ones on 27 Brazilian units during the period from July 2001to February 2008. They released by ANP and through Box-Jenkins methodology. It was empirically verified that relative prices seem to follow a first-order autoregress

11. Um Estudo de Politicas e Práticas do uso do GNV no transporte público urbano do Brasil / A study on policies and practices concerning the use of natural gas vehicle for the urban public transport in Brazil
The use of Natural Gas Vehicle has had a fast increase lately. However, in order to have a continuous success this Program needs to develop converting devices of Otto-cycle engines, gasoline or alcohol, to the use of NGV (Natural Gas Vehicle) that presents low cost, maintaining the same original development of the vehicle and low level of emissions, consider

12. A desregulamentação e o desempenho do complexo sucroalcooleiro no Brasil.
This work analyzed the evolution of the relation between the sugar and alcohol complex and the State from 1975 to 2002, when there was a change from public intervention, marked by Proálcool, to a new situation, in which deregulation is proposed. We attempted to interpret the main political and economical stipulators of the process, as well as describe the w
