Everything added to bad quality by the high content of sulphur, particularly in diesel, which overcomes widely the established international levels. To diversify energy sources, to avoid degraded climatic change and to draw social rejection to polluting energy, become important challenges so that science and technology contribute to a sustainable development, well-known and supported by the citizens.
