Coking. Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke. Coke consists almost entirely of hydrocarbons. The porosity gives it a high surface area, which makes it burn faster (as ...
Metallurgical coke is used in iron and steel industry processes (primarily in blast furnaces) to reduce iron ore to iron. Over 90 percent of the total coke production is dedicated to blast furnace operations. Foundry coke comprises most of the balance and is used by foundries in furnaces for melting metal and in the preparation of molds.

The resource endowment structure of being coalrich and oilpoor makes China's production of coalbased ammonia and urea, with a low production cost and a good market, a competitive advantage. However, the process suffers from high CO2 emissions and low energy efficiency and carbon utilization efficiency due to the mismatch of hydrogentocarbon ratio between raw coal and chemicals. Based on ...
In this study, the composition of tars collected during a sixday underground coal gasification (UCG) test at the experimental mine 'Barbara' in Poland in 2013 was examined. During the test, tar samples were taken every day from the liquid product separator and analysed by the methods used for testing properties of typical coke oven (coal) tar. The obtained results were compared with each ...
1. Introduction. With the continuous growth of crude oil production and the expansion of the refining industry, the production of petroleum coke as a byproduct of the delayed coking process in refineries is also increasing dramatically, reaching million tons in 2021 [1].Petroleum coke accumulating in large amounts not only occupies valuable land resources but also produces particulate ...

Figure 3 represents the ECE process, in which the starting material is the parent coke, and the final product is then exfoliated and separated coke (CKd). The ECE process contains four steps ...
As to the coke products obtained by copyrolysis of coal and biomass, quite different morphological characteristics are observed. During the copyrolysis process, the fine particles of coal are fully adsorbed on the surface of biomass coke, and in close contact with the volatiles, which can be clearly seen that a large amount of coal, particles ...
A similar dependence is the coefficient of thermal expansion of the obtained needle coke samples in the temperature range of 250480 °C, while the lowest CTE for the sample obtained with the addition of 10 wt % polystyrene at 300 °C is × 10 6 °C 1. Thus, polystyrene acts as a modifying agent, which obviously provides the ...
In chemical industry: Benzene. .from the carbonization (heating) of coal, which produces coke, combustible gas, and a number of byproducts, including benzene. Carbonization of coal to produce illuminating gas dates back in England to the very early years of the 19th century. The process is still employed in some countries, but more use is..

During the processing of coal to get the coke, coal tar and coal gas is obtained. Volatile constituents of the coal including water, coalgas, and coal tar are driven off by baking in an airless furnace or oven (kiln ) at temperatures as high as 1, 0 0 0 o C .
Examples are sunlight, air. Exhaustible Natural Resources: The amount of these resources in nature is limited. They can be exhausted by human activities. Examples of these resources are forests, wildlife, minerals, coal, petroleum, natural gas, etc. Here, we will learn about some exhaustible natural resources like coal, petroleum, and natural gas.
Chromatography/mass spectrometry (GS/MS) was used to study toluenesoluble (TS) and pyridinesoluble (PS) fractions obtained from coal liquefaction residue by solvent extraction. It was found that the toluenesoluble fraction, containing mainly polycyclic aromatic hydrocarbons with 24 rings, is a good feedstock for making needle coke. The pyridinesoluble fraction cannot be used for these ...
