The effect of acid washing on the pyrolysis products derived from a vitrinite-rich bituminous coal
Extensive characterization of the pyrolysis products, derived from raw and acid washed samples of a vitrinite-rich South African bituminous coal is reported. Pyrolysis experiments were carried out with use of a modified ...
The effect of added minerals on the pyrolysis products derived from a vitrinite-rich demineralised South African coal
A better understanding of the behaviour of the inorganic matter present in coal will assist in more cost-effective operations and more consistency in product yield and composition during thermal processing. In this study, ...
Chemical and structural characterization of char development during lignocellulosic biomass pyrolysis
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
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 ...
Coal-derived low smoke fuel assessment through coal stove combustion testing
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 ...
Significance of coal properties on the caking degree of coarse coal particles mined at Limpopo Province, Republic of South Africa
(Taylor and Francis, 2020)
In this paper, a comprehensive coal property (chemical, mineralogical, physical, and petrographic) study was conducted using a caking coal from South Africa, density cuts and pyrolyzed samples to understand the % coal ...
