“…A incorporação destas nanopartículas em matrizes poliméricas é devido as suas características e propriedades favoráveis como: (i) menor custo de produção, (ii) menor densidade em comparação com partículas metálicas, (ii) facilidade de preparo de nanopartículas com tamanho e distribuição controlada e (iv) elevada biocompatibilidade [14,15] . Além da característica magnética, estes compósitos apresentam semelhança química com o petróleo (constituído principalmente por hidrocarbonetos saturados, hidrocarbonetos aromáticos, resinas e asfaltenos [16][17][18][19] ). Esta semelhança química torna estes materiais potenciais removedores de petróleo da água.…”

Resumo: A produção de biodiesel foi incentivada pelo desejo de se obter fontes energéticas de origem diferente do petróleo. Este processo, contudo, gera grandes quantidades de glicerina como subproduto. Assim, novas aplicações devem ser encontradas para esta glicerina evitando o colapso da cadeia nacional produtiva de glicerina animal. Uma aplicação mais nobre para esta glicerina, proveniente da indústria de biodiesel, é a produção de resinas alquídicas. Estas resinas podem ser utilizadas como matrizes de compósitos para recuperação de ambientes aquáticos impactados por acidentes de derrames de petróleo. Outra aplicação para estes materiais é na remoção e limpeza de águas produzidas e águas de refinaria, visando a atender a legislação ambiental. Neste trabalho, nanocompósitos espumados magnetizáveis foram preparados pela inserção de nanopartículas magnetizáveis em uma matriz de resina alquídica, obtida a partir da glicerina oriunda do óleo de mamona. Os materiais produzidos foram caracterizados por FTIR-ATR, DRX e SAXS. Além disso, a força magnética destes materiais foi estudada bem como a capacidade de remoção de petróleo derramado sobre água. Os resultados são animadores, pois demonstram a obtenção de um nanocompósito que possui força magnética relativa superior à da maguemita pura. Além disso, este nanocompósito é capaz de remover massas de petróleo cerca de 300% superiores às massas do material usado. Estes materiais, portanto, consistem em uma potencial ferramenta para a recuperação de ambientes aquáticos impactados por acidentes de derramamento de petróleo.

Magnetic Foams Useful in the Environmental Recovery ProcessesAbstract: The biodiesel production was encouraged since the entire world is looking for new energy sources. However, the biodiesel process produces large amounts of glycerin as byproduct. Therefore, innovative uses for this new glycerin source must be sought so as to avoid the collapse of the animal glycerin chain. In this context, the production of resins is interesting due to the likeness between these polymers and the petroleum, with these resins being promising as spill cleanup agents. In the present work, magnetic foams were prepared with insertion of maghemite nanoparticles into in a polymer generated from the glycerin, and were characterized using FTIR-ATR, WAXD and SAXS techniques. In addition, the magnetic force and the oil removal capability of these materials were also studied. The results are encouraging because nanocomposites were obtained which possess magnetic forces larger than for pure maghemite. Furthermore, this nanocomposite is able to remove a petroleum mass around 300% larger than the used mass of the composite, which means that the composite may be important for avoiding environmental disasters owing to the oil spill on the water.

“…The global database on chemical composition and physical properties of oils 3,4 , created at the IPC SB RAS, includes now above 20,000 oil sample descriptions. Information for database was collected from above 600 different sources, for instance [5][6][7][8][9][10][11][12] , Distribution of viscous oils depending on rock age and occurrence depth has been studied in 13,14 . The purpose of this paper is to analyze the spatial distribution of viscous oils and to study the spatial changes in their chemical composition.…”

The spatial distribution of viscous oils which are considered as an important reserve for oil-production in future were studied on base of information from global database on oil physical and chemical properties. Changes in chemical composition of viscous oils in different basins and continents were analyzed as well. It is shown, on average, viscous oils are sulfur-bearing, low paraffin, highly resinous oils with an average content of asphaltenes and low content of the fraction boiling at 200 ï‚°C. Study results of viscous oils peculiarities of Canada, Russia and Venezuela are given. The analysis results can be used to determine the optimal layouts and conditions of oil transportation, to improve the search methods of geochemical exploration, and to solve other problems in the oil chemistry.

In the article, the author summarizes information about the extraction of hard-to-recover oil in various Arctic zones — Russian, Scandinavian and North American. Various estimates of the Arctic hydrocarbon reserves are presented, but the Russian Arctic occupies a leading position in terms of its reserves. The number of deposits in the Russian sector exceeds the number of deposits in the North American and Scandinavian sectors of the Arctic by 4 and 8 times, respectively. For Russia, the Arctic has become one of the main driving forces of the growth of the Russian oil and gas industry in the coming decades. The problems of stabilization and growth of the level of development of hard-to-recover oil in modern conditions of oil production are indicated. Based on the analysis of information from the database of the Institute of Petroleum Chemistry, consolidated information on the development of hard-to-recover oil production in the Arctic zone of Russia, in particular, in the European and Siberian parts of the macroregion, on the physico-chemical properties of hard-to-recover oil, conditions of occurrence and spatial distribution. It has been established that heavy and viscous oils of the Siberian part of the Arctic are characterized by lower viscosity values, low concentrations of asphaltenes, sulfur and metals compared to similar European Arctic oils. The solidification temperature is in the negative temperature range. The established differences determine the features of the development, production and transportation of heavy and viscous oils at critically low temperatures. The article may be of interest to companies in the oil and gas sector net monitor Arctic projects and prospects for their implementation.
