Hydrothermal Carbonization of Biomass Waste for Solid Biofuel Production: Hydrochar Characterization and Its Application in Blast Furnace Injection

open access: yesRecycling
Hydrothermal carbonization (HTC) technology converts biomass into a carbon-rich, oxygen-containing solid fuel. Most studies have focused on hydrochar produced under laboratory conditions, leaving a gap in understanding the performance of industrially ...

Kinetics of the Reduction of Iron Ore Pellets with Hydrogen: A Parametric Experimental and Modeling Study

open access: yesMetals
The direct reduction of iron ore by hydrogen is a serious candidate for reducing greenhouse gas emissions in the iron and steelmaking industry by replacing traditional blast furnace technology. The reduction kinetics are key to this process.

Alkaline carbonates in blast furnace process [PDF]

open access: yes, 2014
The production of iron in blast furnaces is a complex of physical, chemical and mechanical processes. The input raw materials contain not only metallic components, but also a number of negative elements.

Effect of Flow Rate and Partial Pressure of Oxygen on Desulfurization of KR Slag

open access: yesMetals
KR (Kanbara Reaction) desulfurization slag is a solid waste that is not sufficiently utilized. This is because the KR desulfurization slag contains 1–2.5% sulfur, which is directly used in steel smelting to increase the sulfur content in molten steel ...

The Optimal Technological Development Path to Reduce Pollution and Restructure Iron and Steel Industry for Sustainable Transition [PDF]

open access: yes, 2018
China is the world’s largest iron and steel producer and Jing-Jin-Ji (Beijing-Tianjin-Hebei) region accounts for nearly 1/3 of the national iron and steel production, while it is facing serious air pollution.

Comprehensive study of rheological and surface properties of the selected slag system in the context of its internal structure [PDF]

open access: yes, 2016
Rheological (dynamic viscosity, flow curves) and surface properties (surface tension) of real slag system were experimentally investigated. Measurements of dynamic viscosity were performed with use of the high-temperature viscometer Anton Paar FRS 1 ...

Forward and inverse problems in fundamental and applied magnetohydrodynamics

open access: yes, 2012
This Minireview summarizes the recent efforts to solve forward and inverse problems as they occur in different branches of fundamental and applied magnetohydrodynamics. As for the forward problem, the main focus is on the numerical treatment of induction

Towards Zero-waste Mineral Carbon Sequestration Via Two-way Valorization of Ironmaking Slag [PDF]

open access: yes, 2014
A three-stage process was developed to transform blast furnace slag (BFS) into two valuable products: precipitated calcium carbonate (PCC) and zeolitic materials. The conceptualized process aims to simultaneously achieve sustainable CO2 sequestration and

Centrifugal ironmaking. [PDF]

open access: yes
A process for producing liquid iron from iron ore is being developed on the pilot plant scale that avoids the use of high grade metallurgical coal and the agglomeration of iron ore concentrates. The use of a centrifuge furnace provides the maximum surface area for reaction between layers of molten iron oxide and solid carbon.
