Properties of high ash coal-char particles derived from inertinite-rich coal. II. Gasification kinetics with carbon dioxide
(Elsevier Science Limited, 2008)
Quantification of oxygen capture in mineral matter during gasification
(Elsevier, 2008)
It has been observed that during the transformation of minerals at higher temperatures (>1000 °C), mineral species are formed containing a high number of oxygen molecules, i.e. gehlenite (Ca2Al2SiO7), mullite (Al6Si3O15), ...
Radial variation in porosity in annular packed beds
(Elsevier, 2008)
This paper describes the results of a study of the variation in the radial direction in the porosity of annular packed beds. A comparison is made between the predictions by a number of empirical correlations found in ...
A new and innovative look at anti-insulation behaviour in building energy consumption
(Elsevier Science Limited, 2008)
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, ...
An understanding of lump coal physical property behaviour (density and particle size effects) impacting on a commercial-scale Sasol-Lurgi FBDB gasifier
(Elsevier, 2008)
Thermal processes which utilize coarse coal, such as fixed-bed gasification and chain grate stoker boilers, are dependant on a stable particle size for stable operation. During coarse coal utilization, thermal fragmentation ...
Trace element behaviour in the Sasol-Lurgi MK IV FBDB gasifier. Part 1. The volatile elements: Hg, As, Se, Cd and Pb
(Elsevier, 2008)
Coal-fired power and heat production are the largest single source of Hg in the atmosphere, and in March 2005, the US-EPA ruled regarding Hg reduction from coal utilization in the USA. Appropriate Hg pollution control of ...
Introduction to the PBMR heat transfer test facility
(Elsevier, 2008)
This paper provides an introduction to the Heat Transfer Test Facility (HTTF) that is currently being developed for PBMR (Pty.) Ltd. by M-Tech Industrial (Pty.) Ltd. in association with North-West University in South Africa. ...
