Kinetic model for thermal dehydrochlorination of poly(vinyl chloride)
(Elsevier, 2010)
In this paper, a novel method for calculating degradation kinetics is presented. The method has been applied to the thermal dehydrochlorination of two different samples of PVC. It has been observed that this dehydrochlorination ...

Thermal decomposition of dolomite under CO2: insights from TGA and in situ XRD analysis
(Royal Society of Chemistry, 2015)
Thermal decomposition of dolomite in the presence of CO2 in a calcination environment is investigated by means of in situ X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The in situ XRD results suggest that ...

New insights into surface-functionalized swelling high charged micas: Their adsorption performance for non-ionic organic pollutants
(Elsevier, 2017)
The major components of the wastewater from the petroleum refineries are benzene, toluene and phenol and one of the techniques applied to the treatment of effluents is sorption using organo-functionalized clay. The materials ...

On the relevant role of solids residence time on their CO2 capture performance in the Calcium Looping technology
(Pergamon Press, 2016)
The multicycle CO capture performance of CaO derived from natural limestone and dolomite has been investigated by means of thermogravimetry under realistic Calcium-Looping conditions, which necessarily involve high CO ...

The role of carbon nanotubes on the stability of tetragonal zirconia polycrystals
(Elsevier, 2018-10)
The effect of single walled carbon nanotubes (SWNT) at zirconia grain boundaries on the stability of a tetragonal zirconia polycrystalline matrix has been explored in as–sintered composites and after low–temperature ...

Effect of the crystal chemistry on the hydration mechanism of swelling micas
(Elsevier, 2017)
Swelling and dehydration under minor changes in temperature and water vapor pressure is an important property that clays and clay minerals exhibit. In particular, their interlayer space, the solid-water interface and the ...
