The experimental evaluation of nitrogen transformation in South African coal chars and the concomitant release of nitrogenous species
(North-West University, 2018)The effect of typical South African (SA) coal properties on nitrogen functional transformation and release were examined in the course of pyrolysis in a fluidised bed (FB) and drop-tube furnace (DTF). Chars were generated ... -
Transformation of nitrogen functional forms and the accompanying chemical-structural properties emanating from pyrolysis of bituminous coals
(Elsevier, 2018)Characterisation of simultaneous changes in nitrogen functionalities and condensed aromatic crystallites during pyrolysis of bituminous coals was conducted. X-ray photoelectron spectroscopy (XPS) was utilised to determine ...
