Thermogravimetric study of coal-based reduction of oolitic ...

2015-10-10  The increase in the C/O molar ratio (i.e., content of coal) led to the increase of the contact surface area (between oolitic iron ore and coal) and the concentration of CO in the reactor, providing more active sites and stronger driving force for the iron oxide reduction. Therefore, the peak reduction rate was higher at a higher C/O ratio.

Effect of Coal Combustion Products in Reducing Soluble ...

2013-11-29  Phosphorus (P) management in agriculture is crucial for both environmental health and future availability of P resource. Application of P as fertilisers (organic or inorganic) often results in either P accumulation in soil or loss to water bodies, rendering them unavailable to crops. In this study, the mobility of inorganic (KH2PO4 (PP)) and organic (poultry manure

2013-3-24  The study examined the effectiveness of various coal combustion products (CCPs) [fly ash (FA), fluidized bed combustion ash (FBC), and flue gas desulfurization gypsum (FGD)] on phosphorus (P) adsorption in soils using batch sorption studies. The results indicated that P adsorption increased with increasing application rates of CCPs. The effect of CCPs in
