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 ... -
The effect of mineral addition on the pyrolysis products derived from typical Highveld coal
(2014)Mineral matter affect various coal properties as well as the yield and composition of products released during thermal processes. This necessitates investigation of the effect of the inherent minerals on the products derived ... -
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 ... -
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 ... -
Ionizing radiation as imaging tool for coal characterization and gasification research
(North-West University, 2012)In this study, imaging with ionizing radiation was evaluated as a research technique in coal research. Part of the evaluation was to conduct a thorough literature survey as well as a preliminary investigation into coal ... -
Low-smoke fuel production via low temperature pyrolysis of lump coal
(North-West University (South Africa) , Potchefstroom Campus, 2016)Coal is used on a large scale in the Kwadela Township, Mpumalanga, South Africa with the means to fulfil the basic energy requirements of low-income households. Energy within the coal is utilised via combustion thereof in ... -
The molecular structure of selected South African coal-chars to elucidate fundamental principles of coal gasification
(2015)Advances in the knowledge of chemical structure of coal and development of high performance computational techniques led to more than hundred and thirty four proposed molecular level representations (models) of coal ... -
Pyrolysis product evaluation and prediction of coals of different rank
(North-West University (South Africa) , Potchefstroom Campus, 2016)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 tars, oils and non-condensable ... -
