The influence of various potassium compound additions on the plasticity of a high-swelling South African coal under pyrolyzing conditions
(Elsevier, 2015)The influence of the anion attached to a potassium cation on the decrease of plastic properties of a high swelling vitrinite-rich medium rank B South African coal was investigated by adding potassium hydroxide (KOH), ... -
Matrix forming excipients from natural origin for controlled release matrix type tablets
(Elsevier, 2011)Since excipients from renewable sources are attractive due to their sustainable mass production, this study aimed at investigating the use of gel and whole leaf materials from Aloe vera and Aloe ferox to produce controlled ... -
The transient swelling behaviour of large (-20 + 16 mm) South African coal particles during low-temperature devolatilisation
(Elsevier, 2014)In order to predict coal behaviour during certain utilisation processes, and to improve and develop coal conversion technologies, it is important to understand the swelling behaviour and plastic properties of coal. X-ray ...
