Lowering Si Content in Pig Iron by Powder Injection into Blast Furnace

Blast Furnace Granular Coal Injection Project

Blast Furnace Granular Coal Injection System Demonstration Project

The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a sufficiently large scale to prove commercial worthiness and generate data for design, construction, operation, and technica...

The Study of Ion Adsorption by Amorphous Blast Furnace Slag

In this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. For this reason, various experimental parameters such as pH, contact time and the primary ion concentration were investigated. The remaining concentrations of ions such as; Mn2+ and Fe2+ in water were measured by atomic adsorption spectroscopy. The chemical and p...

Removal of Hexavalent Chromium in Portland Cement Using Ground Granulated Blast-Furnace Slag Powder

Using ground granulated blast-furnace slag (GGBS) under different alkaline conditions, we studied the mechanisms and extents of Cr(VI) reduction and sorption and compared them to reactions with Portland cement (PC). We also investigated the effects of mixing PC/GGBS ratios on Cr(VI) dissolution after carbonating the substrates. We observed a complete sorption and reduction of Cr(VI) to Cr(III) ...
