Kinetics of the low-temperature pyrolysis of walnut shell
The walnut shell with particle size less than 0.154 mm pyrolysis mass loss behaviour was studied at different heating rates (5, 10, 20, 30, 40?C/min) using pyris1 thermogravimetric analysis (TGA) instrument. Results showed that the activation energies of walnut shell pyrolysis under the different fractions decomposed were centred on 134?172 kJ/mol by Ozawa method and Kissinger?Akahira?Sunose ...

Characterisation of humic acid maturation by fluorescence spectroscopy and thermal analysis during composting of olive mill waste
Humic acids isolated from different stages of olive mill waste composting were investigated by Elemental analysis, Fluorescence spectroscopy and by Differential Scanning Calorimetry (DSC). The Elemental composition of these humic acids indicates an increase in aromatic structures during the composting. Indeed, the fluorescence results showed an increase in condensed aromatic ring systems. ...

Microstructural characterisation of keratin fibres from chicken feathers
Natural fibres have recently attracted scientists' attention because of their advantages from the environmental standpoint. However, almost all the research has been directed towards cellulose from vegetal sources without taking into account other potentially interesting compounds like keratin, which can be found in feathers, wool, nail or hair. In spite of its strength, low density and ...
