Trace metals in sediments from the "Ria de Huelva"
(Gordon and Breach Science, 1991)
The Ría de Huelva is an estuarine zone into which flow the Odiel and Tinto rivers, polluted by trace metals. Total contents of Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Pb, Cd and Hg were determined in the < 630 and < 63 μm ...

Oxidative degradation of a novel AMP/AEP blend designed for CO2 capture based on partial oxy-combustion technology
(Elsevier, 2018-10)
Solvent degradation and volatile compound emissions are two of the major concerns about the deployment of carbon capture technologies based on chemical absorption. In this context, partial oxy-combustion might reduce the ...

Influence of the Stoichiometric Ratio on Tar Composition during Fluidized Bed Gasification
(EUBCE, 2017)
Fluidized bed gasification is a promising technology for the energetic valorization of biomass and wastes. However the presence of heavy tars limits the use of the gas to applications where the gas is not cooled. Several ...

Ignition behavior of single coal particle in a fluidized bed under O2/CO2 and O2/N2 atmospheres: A combination of visual image and particle temperature
(Elsevier, 2014)
Single coal particle ignition behavior was studied in a two-dimensional (200 mm × 20 mm × 400 mm) fluidized bed under O2/N2 and O2/CO2 atmosphere with O2 volume concentration in the range of 0–40%, by a combination of ...
