In this study was conducted on the weathering of petroleum by evaporation with aim investigating changes in chemical profile saturated hydrocarbon fraction four chromatography coupled mass spectrometry (GC-MS). The samples (AMB1, AMB2, AMB3, AMB5, AMB1Ev, AMB2Ev, AMB3Ev and AMB5Ev) were characterized respect to density, kinematic dynamic viscosity, pour point, sulfur content asphaltenes content, asphaltene total acid number salinity index. compounds analyzed GC-MS obtained fractionating...
In this work, different synthesis routes from the anode and cathode of a spent nickel metal hydride (Ni-MH) battery were studied for purpose producing ceramic precursors formation titanate (NiTiO3). The subjected to heat treatments at temperatures form NiTiO3. content Ni-MH battery’s active devices was determined by inductively coupled plasma optical-emission spectrometry. contents characterized thermogravimetry, Fourier-transform infrared spectroscopy, Raman scanning electron microscopy...
