Chemical and structural characterization of char development during lignocellulosic biomass pyrolysis
(Elsevier, 2017)
The chemical and structural changes of three lignocellulosic biomass samples during pyrolysis were investigated using both conventional and advanced characterization techniques. The use of ATR-FTIR as a characterization ...
Evaluation and prediction of slow pyrolysis products derived from coals of different rank
(Elsevier, 2017)
When coal is heated slowly (<10 °C/min), as in the Lurgi Fixed Bed Dry Bottom (FBDB) gasification process, products formed in the pyrolysis region of the gasifier include gas liquor, condensable tar, oil and non-condensable ...
The effect of acid demineralising bituminous coals and de-ashing the respective chars on nitrogen functional forms
(Elsevier, 2017)
An opportunity presented itself to compare changes in nitrogen functional forms brought by the acid treatment of South African bituminous coals and their respective chars. X-ray photoelectron spectroscopy (XPS) was used ...
Coal-derived low smoke fuel assessment through coal stove combustion testing
(Elsevier, 2017)
A study was undertaken to investigate the production of low smoke fuel from coal currently used in low-income households in South Africa. Pyrolysis of large coal lumps was studied as a possible production method, and an ...
