Coal combustion by-products such as fly ash (FA), brine and CO2 from coal fired power plants have the potential to impact negatively on the environment. FA and brine can contaminate the soil, surface and ground water through ...

The title imino–phosphine compound, [PdCl2(C26H22NP)] - CH3CN, was prepared by reaction of N-[2-(diphenylphosphanyl) benzylidene]-2-methylaniline with dichlorido(cycloocta- 1,5-diene)palladium(II) in dry CH2Cl2. The ...

In this study, high phase purity of zeolite A was prepared from coal fly ash precursors. The molar regime of both the clear solution extract and unseparated fly ash slurry was adjusted to achieve the right composition for ...

Several studies have been carried out on the production of biodiesel using different heterogeneous catalysts but this study has been able to demonstrate the prospect of utilizing South African class F fly ash as a raw ...

South Africa is largely dependent on the combustion of coal for electricity production; Eskom’s coalfired power stations consume approximately 109 million tons of coal per annum, producing around 25 million tons of ash, ...
