Author:Engelbrecht, AS; North, Brian C; Oboirien, BO; Everson, RC; Neomagus, HWPJDate:Nov 2011The gasification of two high-ash coals were studied using a pilot scale fluidised bed gasifier using oxygen enrich air and steam as the gasification agents. The results of the tests show that the fixed carbon conversion and calorific value ...Read more
Author:Oboirien, BO; North, Brian C; Sadiku, ERDate:Sep 2013Fluidised bed gasification (FBG) is a clean coal technology suitable for power and fuel generation from low grade coals. However, the resulting bottom ash presents some disposal challenges to the power plants and the environment. The production ...Read more
Author:Oboirien, BO; Engelbrecht, AD; North, Brian C; Du Cann, VM; Verryn, S; Falcon, RDate:Oct 2009The gasification characteristics of three South African bituminous coals were investigated in a bubbling fluidised bed reactor. The three coals are similar in rank, but two are inertinite-rich coals and the third has high vitrinite content. ...Read more
