1. 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

2. Invasão de fluidos de perfuração e fluxo reverso de óleo em reservatórios de arenito e de carbonato / Invasion of drilling fluids and oil backflow in sandstone and carbonate reservoirs
As recentes descobertas do pré-sal no Brasil trouxeram novos desafios para as atividades de explotação de petróleo. Perfuração em formações carbonáticas apresentam grandes diferenças em relação a perfurações em rochas areníticas. Enquanto arenitos são mais homogeneos, rochas carbonáticas podem apresentar significativas variações em relaç�

3. Alternativas técnico produtivas para o aproveitamento do gás natural da camada pré-sal / Technical productive alternatives to the use of natural gas in pre-salt layer
The Brazilian reserves of oil and natural gas will present a significant growth from the development of the reserves of the pre-salt layer. According to estimates prepared by the EPE and the EIA, the next twenty years, the supply of natural gas will exceed demand. As the transportation sector natural gas has great importance in the formation of the cost of e

4. Estudos em adsorÃÃo de gÃs natural: armazenamento, transporte e purificaÃÃo / Studies of Natural Gas Adsorption: Storage, Transport and Purification
The use of vessels filled with activated carbon to store and transport natural gas (NG) at moderate pressures (about 3.5 MPa) and ambient temperature (about 298 K) has been studied as a potential alternative to compressed natural gas storage at high pressures (ca. 20 MPa). The present study provides an experimental investigation of charge and discharge cycle

5. MODELAGEM MATEMÁTICA DE DERRAMES CRIOGÊNICOS E DE INCÊNDIOS EM POÇA NO TRANSPORTE MARÍTIMO DE GÁS NATURAL LIQUEFEITO (GNL) / MATHEMATICAL MODELING OF CRYOGENIC SPILLS AND POOL FIRES IN THE LIQUEFIED NATURAL GAS (LNG) MARITIME TRANSPORTATION
Gás Natural Liquefeito (GNL) vem sendo transportado desde 1959 em navios metaneiros, elos essenciais na movimentação do GNL entre as locações de produção e consumo. Este trabalho apresenta modelagens para: (i) mecânica do derrame e espalhamento de fluido criogênico no mar, decorrente de punção no casco desses vasos, e (ii) subsequente incêndio de

6. Integrated dispatch of thermoelectric generation and production and transport of natural gas with Newton s method / Despacho integrado da geração termeletrica e da produção e transporte de gas natural com metodo de Newton
O gás natural é um combustível fóssil que pode ser utilizado tanto na indústria como no comércio, residências e veículos. Uma aplicação importante do gás natural é como fonte primária para geração de energia elétrica em usinas termelétricas. Seu uso possibilita uma maior estabilidade ao Sistema Elétrico Brasileiro, pelo fato de depender men

7. Avaliação da remoção de sulfeto de hidrogênio do gás natural em uma coluna de absorção
Natural gas, although basically composed by light hydrocarbons, also presents in its composition gaseous contaminants such as CO2 (carbon dioxide) and H2S (hydrogen sulfide). Hydrogen sulfide, which commonly occurs in oil and gas exploration and production activities, besides being among the gases that are responsible by the acid rain and greenhouse effect,

8. Desenvolvimento e caracterização de nanocompósito de resina epóxi com nanopartículas de sílica para revestimento de dutos para transporte de petróleo
The use of polymer based coatings is a promising approach to reduce the corrosion problem in carbon steel pipes used for the transport of oil and gas in the oil industry. However, conventional polymer coatings offer limited properties, which often cannot meet design requirements for this type of application, particularly in regard to use temperature and wear

9. Síntese e caracterização de NiO-CGO para anodo e eletrólitos sólidos e base de Céria para SOFC
The direct use of natural gas makes the Solid Oxide Fuel Cell (SOFC) potentially more competitive with the current energy conversions technologies. The Intermediate Temperature SOFC (IT-SOFC) offer several advantages over the High Temperature SOFC (HT-SOFC), which includes better thermal compatibility among components, fast start with lower energy consumptio

10. Evaluation of the Fluid Dynamic Properties and Kinetic Study by Pressurized Differential Scanning Calorimetry (PDSC) of Ethanolic Biodiesel Derived from Used Frying Oil / Avaliação das Propriedades Fluído-dinâmicas e Estudo Cinético por Calorimetria Exploratória Diferencial Pressurizada (PDSC) de Biodiesel Etílico Derivado de óleo de fritura usado
The present work aimed at investigating the biodiesel issuing from the transesterification of used frying oil with ethanol, via alkaline catalysis. Such investigation covers its thermo-oxidative stability during heating (thermal analysis and rheological properties) as well the kinetic profiles of the samples in the best oxidative induction time by the techni

11. Regulator conflicts in natural gas transport / Conflitos regulatórios no transporte de gás natural
This dissertation regards to the principal regulator conflicts in natural gas transport (movement) area in Brazil, especially with reference to the limit that exists between the regulator competency of Petroleum National Agency, Natural Gas and Biofuels (PNA) and Regulator State Agencies. This broaching was made in according to the legislation, doctrine, jur

12. O princípio constitucional da redução das desigualdades regionais e o transporte de gás natural / The constitutional principle of regional inequalities reduction and the natural gás transport
In a country of continental dimensions as Brazil, one of the top challenges to its economic growth is the logistic related to energetical demand supply. We live now in the era of environmental protection and, in this new context of priorizations, it passes trough the search for alternative energies for the energetic matrix, due the petroleum elevated costs i
