Blended Coal Coking
,
Coal is usually the most cost effective and economically sensible option for producing energy in many parts of the world. As a result, it is important for many countries to be able to convert it into a usable form, particularly for applications such as steel production. One of the ways to do this......

Henderson-Hasselbalch-Ostwald (HHO) Model
The Henderson-Hasselbalch-Ostwald (HHO) model is a thermodynamically based, equilibrium description of chemical processes. Developed over a century ago, the model is still widely used to describe the behavior of some substances in solution. By representin......
Decarburization of the surface layer of special steel
The surface decarbonization of special steel is a key process in metallurgical production. It is an important measure to improve the cleanliness, corrosion resistance and fatigue strength of the steel. On the other hand, the decarbonization process is of great importance for the subsequent processi......

The Flame Test
The flame test is an analytical technique used to identify a sample based on the characteristic color it produces when its atoms are excited by the heat from a flame. This process is used mainly in inorganic chemistry to identify metal ions in compounds that are easily vaporize......
Hydrazine reduction method
Reduction of Acetylene to Ethylene by Means of Ammonia
Introduction
The reduction of acetylene to ethylene is of great interest since many organic compounds including olefins, such as ethylene and propylene, are derived from it. The reactions involved in the conversion of acetylene to ethylene a......
Sulfur dioxide reduction method
Reduction of Sulphur Dioxide with Hydrogen
Sulphur dioxide (SO2) is a major environmental pollutant. It is produced from many sources such as coal fired power plants and industries. Its presence in the atmosphere may cause significant health problems and can also lead to acid rain. Due to the env......

Iron-Carbon-Oxygen and Iron-Hydrogen-Oxygen Equilibria
The iron-carbon-oxygen (Fe-C-O) and iron-hydrogen-oxygen (Fe-H-O) equilibria play an important role in mineral processing, thermodynamic modeling of processes, and product performance. A thorough understanding of both systems is essential for......
Austenitic essential grains of steel
Austenite is a non-magnetic and highly ductile phase of iron-carbon alloys. In metallurgy, it is sometimes referred to as gamma iron. Austenite exists at high temperatures and it is the face-centered cubic (FCC) form of iron. At temperatures below 912°C (1674°F), an iron-carbon alloy will form a......
chemical transfer reaction
Chemical Transfer Reaction
Chemical transfer reactions are chemical reactions in which an atom or group of atoms is transferred from one molecule to another. The reactions occur between an electron donor and an electron acceptor and involve the transfer of electrons from one molecule to another. ......
iodide thermal decomposition method
Iodine Dissociation Heat Analysis
The iodine dissociation heat analysis (DA) is an important analytical technique that is used in the analysis of iodine species in liquid and solid samples. This technique is based on the fact that the enthalpy of a reaction (the energy released or absorbed by the......
