Robust and Reversible Supramolecular Adhesive via Dynamic Covalent Bond Crosslinking‐Induced Assembly of Metal‐Coordinated Nanoparticles

Advanced Science, EarlyView.
A supramolecular polymer network is constructed through the assembly of metal‐coordinated nanoparticles induced by the crosslinking of dynamic covalent disulfide bond. The resulting supramolecular adhesive exhibited excellent adhesion performance, including strong adhesion strength, exceptional solvent resistance, and distinct reversible adhesion ...

Interface wetting behavior between iron and coke during the carbon dissolution process in a blast furnace

工程科学学报, 2020
Good gas permeability is an essential factor for the smooth operation and high performance in the lower part of the blast furnace. Under the present low carbon blast furnace smelting conditions, the coke layer is thinner, and the proportion of the molten

Loss of Height Pressure in a Layer of Granular Materials

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2019
During the air blown in the furnace, from the vents to the loading mouth, the gases lost from the initial pressure depend on several factors, such as the care and the granulation mixed with ores and coke from the layers of care.

Quantification of the Existence Ratio of Non-Adhesion Grain Boundaries and Factors Governing the Strength of Coke Containing Low-Quality Coal

Journal of Thermal Science and Technology, 2012
“Non-adhesion grain boundaries” are formed when low-quality coal grains do not adhere to other grains in the carbonization process because of the low dilation of coke.

Numerical Study on Combustion Behavior of Semi-Coke in Blast Furnace Blowpipe-Tuyere-Combustion Zone

Metals, 2022
Injecting low-cost semi-coke is critical to reducing blast furnace production costs. The combustion behavior of the co-injection of semi-coke and undersized coke powder is still rarely studied. In this work, a three-dimensional CFD mathematical model was

Statistical models of diffusion and aggregation for coke formation in a catalyst pore [PDF]

, 2004
We simulated models of diffusion and aggregation in long pores of small widths in order to represent the basic mechanisms of coke deposition in catalysts' pores. Coke precursors are represented by particles injected at the pore entrance.
