description Publicationkeyboard_double_arrow_right Part of book or chapter of book 2023 FrancePublisher:Array Ketzer, João Marcelo; Viana, Adriano; Miller, Dennis; Augustin, Adolpho; Rodrigues, Frederico; Praeg, Daniel; Cupertino, José;O presente capítulo faz uma introdução geral sobre o tema hidratos de gás naturais, i.e., que ocorrem nos sedimentos, apresentando os tipos existentes, como se formam, os principais gases envolvidos, a sua importância econômica e ambiental (incluindo mudança climática e como geohazards), além de suas ocorrências naturais no mundo. A seguir é apresentado um breve histórico dos estudos e da exploração de hidratos de gás no Brasil, seguido de uma descrição das ocorrências naturais confirmadas no país, no leque do Amazonas (Bacia da Foz do Amazonas) e no Cone de Rio Grande (Bacia de Pelotas). Por fim é apresentada uma breve comparação entre as duas ocorrências e uma discussão sobre o desenvolvimento futuro da exploração de hidratos de gás no país. This chapter starts with an introduction of the topic of natural gas hydrates, presenting the main existing types, how they form, the main gases involved in their formation, their economic and environmental (including climate change and as geohazards) importance, in addition to their worldwide natural occurrences. Also included is a brief history of the study and exploration of gas hydrates in Brazil, and a description of the two confirmed occurrences in the country: The Amazon fan (Foz do Amazonas basin) and the Rio Grande Cone (Pelotas Basin). The chapter ends with a brief comparison between the two occurrences and a discussion about the future development of the exploration for gas hydrates in the country. National audience

So, fast pyrolysis is the purpose of several researches all over the world for the production of bio-oils that can enrich the energetic supply. However, bio-oil has heterogeneous properties due to the biomass characteristics and to the operational conditions of the pyrolysis process. The present review aims to evaluate the state of art of the bio-oil production, their properties and their principal energetic ways of utilization. (Résumé d'auteur)

Verificou-se o aumento das temperaturas, ligeiramente maiores em Rennes, do que em Presidente Prudente e a geração de ilhas de calor urbanas (ICU), decorrentes do processo de urbanização nas duas cidades. This paper aims to analyze and compare thermal characteristics of urban climate of two middle size cities: Rennes (France) and Presidente Prudente (Brazil), by registering air temperature (network pointes and mobile transect) and surface data obtained by using Landsat7 satellite thermal images. Results shows that temperature grows faster in Rennes than Presidente Prudente and urban heat island generation (UHI) by different cities urbanization processes.
