Fate of sulphate removed during the treatment of circumneutral mine water and acid mine drainage with coal fly ash: Modelling and experimental approach
Madzivire, Godfrey; Gitari, Wilson; Vadapalli, V.R. Kumar.; Ojumu, Tunde V.; Petrik, Leslie (Elsevier, 2011)The treatment of acid mine drainage (AMD) and circumneutral mine water (CMW) with South African coal fly ash (FA) provides a low cost and alternative technique for treating mine wastes waters. The sulphate concentration ... -
The production of hydrogen through the use of a 77 wt% Pd 23 wt% Ag membrane water gas shift reactor
Baloyi, Liberty N.; North, Brian C.; Langmi, Henrietta W.; Bladergroen, Bernard Jan; Ojumu, Tunde V. (Elsevier, 2016)Hydrogen as an energy carrier has the potential to decarbonize the energy sector. This work presents the application of a palladium-silver (PdeAg) membrane-based reactor. The membrane reactor which is made from PdeAg ... -
Synthesis of zeolites Na-P1 from South African coal fly ash: effect of impeller design and agitation
Mainganye, Dakalo; Ojumu, Tunde V.; Petrik, Leslie (MDPI, 2013)South African fly ash has been shown to be a useful feedstock for the synthesis of some zeolites. The present study focuses on the effect of impeller design and agitation rates on the synthesis of zeolite Na-P1 which are ... -
Waste minimization protocols for the process of synthesizing zeolites from South African coal fly ash
Du Plessis, Pieter W.; Ojumu, Tunde V.; Petrik, Leslie (MDPI, 2013)Production of a high value zeolite from fly ash has been shown to be an avenue for the utilization of South African fly ash which presently constitutes a huge disposal problem. The synthesis of zeolites Na-P1 and analcime ...
