Author:Oboirien, BO; Engelbrecht, AD; North, Brian C; Eramus, RM; Falcon, RDate:Sep 2011The mineral-char interaction can occur during the gasification of high-ash coals in fluidized-bed gasifiers when the melted minerals cover the char surface by penetrating into the cracks and pores of the char. In addition to the physical ...Read more
Author:Oboirien, BO; Engelbrecht, AD; North, Brian C; Du Cann, VM; Verryn, S; Falcon, RDate:Apr 2011The 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 a high vitrinite content. ...Read more
Author:Oboirien, BO; Engelbrecht, AD; North, Brian C; Du Cann, VM; Falcon, RDate:Nov 2012In this study, the textural properties of chars generated from a vitrinite, high ash coal in a fluidised bed gasifier under air-blown, oxygen-blown and oxygen-enriched conditions were determined by detailed petrographic analysis. The char ...Read more
