Effect of mineral matter removal on pyrolysis of wood sawdust from an invasive species
(Taylor, 2016-02)
Kinetics of the pyrolysis of wood sawdust from the invasive species Parkinsonia aculeata, untreated and demineralized by a mild acid treatment, is comparatively investigated in order to examine the effect of the removal ...
Cellulose-Lignin interactions during slow and fast pyrolysis
(ELSEVIER, 2015-07-01)
The interactions between lignin and cellulose during the slow pyrolysis of their blends were studied by means of Thermogravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM). Fast pyrolysis was studied using ...
