Resumo: | Gas hydrates are solids formed by crystal structures similar to ice, which may form when the water is in contact with low weight molecular gases (such as H2S, CO2, NH3 and/or light hydrocarbons), under certain conditions of temperature and pressure. Several studies show that gas hydrates may be a wide source of natural gas in the future, especially considering the fact that oil production tends to decline due to the high cost involved, which makes the interest in alternative sources, such as natural gas derived from unconventional sources, grow. However, in order to make gas hydrate exploitation possible, it's necessary to know how they are formed and what are the conditions that provide stability and dissociation. Different apparatus have been used to obtain gas hydrate. In this scenario, the present paper aims to use a unique system called Pilot Plant Synthesis of Gas Hydrates to synthesize different hydrates, with different compositions, in various reaction conditions. It is noticed that the present study was based on the synthesis of hydrates with its precipitation of at larger scales. The methane hydrates were characterized by X-ray diffractometer, Gas Chromatograph and Gas Chromatography Isotope Ratio Mass Spectrometer. |

Diversos estudos mostram que os hidratos de g?s poder?o ser uma vasta fonte de g?s natural considerando, especialmente, o fato da produ??o de petr?leo estar propensa a diminuir, em raz?o do elevado custo desta atividade, o que faz crescer o interesse por outras fontes, como o g?s natural derivado de fontes n?o convencionais. Entretanto, para que a explora??o do g?s do hidrato seja poss?vel, faz-se necess?rio conhecer a maneira como estes s?o formados e quais s?o as condi??es que propiciam a sua estabilidade e dissocia??o. Diferentes aparatos j? foram utilizados para a obten??o dos hidratos de g?s at? os dias de hoje. Neste cen?rio, o presente trabalho se prop?e a utilizar um sistema in?dito (denominado Planta Piloto de S?ntese de Hidratos de G?s) para sintetizar diferentes hidratos de g?s, com diferentes composi??es dentro de variadas condi??es reacionais. Salienta-se que este estudo foi baseado na s?ntese de hidratos de metano, com a precipita??o dos mesmos em maiores escalas. Os hidratos de metano foram caracterizados atrav?s da difratometria de raios-X, na cromatografia gasosa e cromatografia gasosa acoplada ? Espectrometria de Massa de raz?o isot?pica.Made available in DSpace on 2015-04-14T13:59:14Z (GMT).
