The technology of fluidized bed coal combustion (FBC) and its advantages over conventional coal burning systems is now well established and is extensively reported in the literature. There is also some emphasis in literature about the suitability of Lafia-Obi coal in FBC. However, there is little.

Two Nigerian coals, Lafia-Obi and Chikila were blended in the mass ratio of 70:30 with imported American and Polish coking coals. Proximate analysis, free swelling index, Ruhr dilatometer and Gieseler plastometer were used in assessing the coking qualities of both the single coals and the blends. The results show that.

Mar 31, 2016 . Jauro and Chukwu  investigated three Nigerian coals (Onyeama, Lafia-Obi, and Garin Maiganga) to determine their suitability in developing formed coke for use as blast furnace coke. Parameters that were used include the shatter index expressed as percentage stability and friability and mecum index.

Feb 21, 2013 . The youngest sediment is the Maastrichtian Lafia Formation. One sediment of interest is the Agwu Formation. The Coniacian Agwu Formation consists mainly of black shale, sandstones, and local seams of coal. Around the Obi/Lafia area, this Formation is coal-bearing and has been shown to fall within the.

Petrographic studies and proximate analysis of coal samples from Lafia-Obi, Chikila and Lamza deposits of the Benue Trough, were used in the ranking and preliminary assessment of the coking potential. Vitrinite reflectance measurements show that the Lafia-Obi is of high volatile A rank, while both the Lamza and Chikila.
This, combined with petrography and Rock-Eval pyrolysis were used in assessing the hydrocarbon generating potentials of the coal samples. Lafia-Obi coals were found to have a percentage vitrinite reflectance (%R o ) values of 0.91-1.08 %, maximum temperature for hydrocarbon generation (T max ) of 449-455 oC and a.
implementation and maintenance of imported mining equipment proved troublesome and hurt production. (Godwin, 1980). Coal exploration in Nigeria started as far back as 1916. Available data show that Coal (mainly sub-bituminous steam Coals except for the Lafia-Obi bituminous Coking Coal) occurrences in Nigeria.
General Background There is a large deposit of coal in the middle belt and eastern part of the Nigeria which remains underexploited. The coal reserves in Nigeria are estimated to be in excess of 2.5 billion tonnes. Available data show that Nigerian coals are mainly sub-bituminous steam except for the Lafia-Obi bituminous.
