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 ... -
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 ... -
Product evaluation and reaction modelling for the devolatilization of large coal particles
(North-West University, 2012)A fundamental understanding of the process of devolatilization requires extensive knowledge of not only the intrinsic properties of the parent coal and its subsequent formed products (tars, gases and chars), but also its ... -
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 ...
