Behaviour of calcium-containing minerals in the mechanism towards in situ CO2 capture during gasification
(Elsevier, 2008)Mineral matter transformation and the behavior of mineral matter in the coal during gasification, provide more information on the suitability of a specific coal source for combustion or gasification purposes. Therefore, ... -

Coal and coal ash characteristics to understand mineral transformations and slag formation
(Elsevier, 2009)A knowledge of the composition and structure of minerals in coal is necessary in order to understand the mineral transformations and agglomerate or slag formation during combustion or gasification. Coal ash fusibility ... -
Coal particle chemical transformational behaviour after thermochemical conversion in a fixed bed
(Elsevier, 2016)This paper examines the chemical transformational behaviour that coal particles undergo during conversion in deep packed beds, typically found in industrial combustion and gasification operations. Experiments were performed ... -
The influence of calcium lignosulphonate addition on non-isothermal pyrolysis and gasification of demineralised bituminous coal fines
(Elsevier BV, 2022)Amorphous calcium lignosulphonate (CaLS), a by-product of the paper industry, was evaluated as an adhesive to bind demineralised bituminous coal fines in various weight percentage ratios. Sequential acid (HCl, HF, ... -
Pipe reactor gasification studies of a south african bituminous coal blend. Part 1. Carbon and volatile matter behaviour as function of feed coal particle size reduction
(Elsevier, 2009)The Sasol-Lurgi fixed-bed dry-bottom (FBDB) MKIV gasifiers are proven to be robust as far as acceptable coal properties are concerned, in particular its ability to accommodate a range of particle size distributions (PSD) ... -
Viscosity predictions of the slag composition of gasified coal, utilizing FactSage equilibrium modelling
(Elsevier, 2009)Agglomeration of ash particles provides the desired porosity of the ash bed for adequate agent (steam and oxygen) flow and distribution, whereas excessive slagging inside the gasifier can cause channel burning, pressure ...
