Magnetic Fe2O3/carbon hybrids were prepared in a two-step process. First, acetic acid vapor interacted with iron cations dispersed on the surface of a nanocasted ordered mesoporous carbon (CMK-3). In the second step, the primarily created iron acetate species underwent pyrolysis and transformed to magnetic iron oxide nanoparticles. X-ray diffraction, Fourier-transform infrared, and Raman ...

Ironmaking Process - an overview | ScienceDirect Topics

The sponge iron reaction (SIR) is a chemical process based on redox cycling of an iron-based contact mass, the first cycle is a conversion step between iron metal (Fe) and wuestite (FeO), the second cycle is a conversion step between wuestite (FeO) and magnetite (Fe 3 O 4). In application, the SIT is used in the reformer sponge iron cycle (RESC) in combination with a steam reforming unit.

Metallurgic Processes | Boundless Chemistry

Steel is made primarily in a two-step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.

Apr 30, 2014· Notice that the 12 C output in the sixth step goes back into the process as an input in the first step. The last step in this process has an alternate outcome: 15 N + H → 16 O + γ 16 O + H → 17 F + γ 17 F → 17 O + e + + ν 17 O + H → 14 N + 4 He. The 14 N created in the fourth step of this second process can be inputted into the ...
