The renewable and non-renewable exergy and CO2 costs of petroleum derived fuels produced in Brazil are evaluated using exergoeconomy to rationally distribute the exergy costs and the CO2 emitted in processes with more than one product. An iterative procedu ...
Due to the continuous development of warm mix asphalts (WMA) as alternatives to hot mix asphalts (HMA), the choice of the most favourable mixture for a given project is not necessarily straightforward. When considering greenhouse gas (GHG) emissions and en ...
Natural seeps contribute nearly half of the oil entering the coastal ocean. However, environmental fate studies generally monitor fewer than 5% of these petroleum compounds. Hence, the rates and relevance of physical, chemical, and biological weathering pr ...
We describe a mass spectra recalibration method, which enables analysis of petroleum samples with Orbitrap FTMS. In this method, the mass calibration function is estimated on the basis of mass-to-charge ratios and abundances of internal calibrants without ...
As a substantial source of greenhouse gas (GHG) emissions and energy consumption, the road construction domain has to bring a contribution to the reduction of the environmental impacts. Indeed, an important part of the energy consumption and consequently e ...
By decreasing the mixing and laying temperatures, warm mix asphalts (WMA) allow a reduction of the energy consumption as well as the emissions, thus contributing to the sustainable development. However researches are necessary for these asphalt mixtures to ...
Blends of biodiesel and petrodiesel are being used increasingly worldwide. Due to several factors, inaccurate blending of these two mixtures can occur. To test the accuracy of biodiesel blending, we developed and validated a radiocarbon-based method and th ...
Temperature variations are particularly harmful to wearing courses with asphalt mixture. During wintertime, and especially, at very low temperatures, a surface cracking may appear and propagate more or less rapidly. An experimental investigation has been c ...
An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...
The performance of the high-field Orbitrap Fourier transform mass spectrometer (FTMS) is evaluated in the context of petroleum sample analysis. Pertinent characteristics including resolving power, mass accuracy, and spectral dynamic range are tested with r ...
