Investigation of lump coal agglomeration in a non-pressurized reactor

Campbell, Q.P.; Bunt, J.R.; De Waal, F. (Elsevier, 2010)

The overall aim of this research was to investigate the agglomeration phenomenon of large coal particles (8 cm3 blocks) of three South African non-swelling coals (based on FSI) under various laboratory conditions. The coals ...
An understanding of the porosity of residual coal/char/ash samples from an air-blown packed bed reactor operating on inertinite-rich lump coal

Bunt, J.R.; Waanders, F.B.; Nel, A.; Dreyer, L.; Van Rensburg, P.W.A. (Elsevier, 2012)

The thermal treatment of coal causes a development of internal porosity of the resultant char due to the changes in the coal char pores, i.e. the opening of original closed pores, the formation of new pores, and an ...
