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, ... -

The behaviour of potassium and sodium species during the thermal treatment of a demineralized Highveld coal
(North-West University, 2011)A series of experiments was conducted to investigate the potential influence of pre- and post adding of catalysts to a demineralized coal char. The catalysts were chosen according to yield better catalytic activity and be ... -
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 ... -
Comparison of industrial wastes as binder in the agglomeration of coal fines
(North-West University (South Africa)., 2021)The industries that consumed the most coal in South Africa, in 2015, were electricity generation, 53%, basic iron and steel manufacturing, 20%, and synthetic fuel and chemical industries, 10%, with the rest being used in ... -
Evaluation of the gasification reactivity of Highveld coals for application in the coal to liquids process
(North-West University (South Africa) , Potchefstroom Campus, 2017)Coal is a very heterogeneous substance with widely varying properties from one source to another, requiring continuous analysis to determine the properties and reaction behaviour of coals as new sources become mined. There ... -
Fluidised bed gasification of high-ash South African coals : an experimental and modelling study
(2014)South Africa has large coal reserves and produces approximately 74% of its primary energy from coal. Coal gasification using moving bed gasifiers is one of the most important coal utilisation technologies, consuming ± ... -
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, ... -
Investigation of coal agglomeration in a non-pressurized gasifier
(North-West University, 2008)The gasification process is vital to various applications, such as the manufacture of products in the petrochemical industry, for example chemicals, diesel and petrol. The importance of gasification to the coal industry ...
