1. Introduction. Coal is deemed to be the main energy resource and therefore plays a crucial role in social development. Inefficient and extensive coal utilisation not only causes serious waste of energy but also bring a series of environmental pollution problems [Citation 1].It is urgent to meet the requirement of energy utilisation by promoting energy conservation and carbon reduction in the ...
Cool in a desiccator and weigh. The loss in weight represents moisture. On further heating it will be found that this loss increases, but any pyrites present is apt to oxidise; therefore it is preferable, when examining coals, to treat all alike for thirty minutes, and consider the result as moisture.

Powdered activated coke (PAC) is a good adsorbent of SO2, but its adsorption capacity is affected by many factors in the preparation process. To prepare the PAC with a high SO2 adsorption capacity using JJcoal under flue gas atmosphere, six parameters (oxygencoal equivalent ratio, reaction temperature, reaction time, O2 concentration, CO2 concentration, and H2O concentration) were screened ...
The purpose of this work is to understand the semicoke explosion issues and to improve the safety in semicoke injection. It shows that the higher pyrolysis upgrading temperature is, the lower explosibility of semicoke powder has. The effects of pore structure and functional groups on explosive properties are evaluated in detail. The surface area is determined to be at least as important as ...

Coal liquefaction pitch is a type of complex polycyclic aromatic hydrocarbon with a high molecular weight and viscosity, which is produced via the extraction of coal direct liquefaction residue and can be employed as a raw material to produce needle coke in theory. 24,25 However, the high viscosity of coal liquefaction pitch makes it difficult ...
1. Introduction. The global production of crude steel was billion tons in 2020, and the average energy consumption for the blast furnace/basic oxygen furnace (BF/BOF) dominating ironmaking routine is approximately tce/t crude steel [1], [2].To date, BF is the most energyefficient metallurgical reactor, consuming the major portion of energy, mainly coal and coke, in iron and steelmaking.
Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
The invention discloses a method for determining the content of pulverized coal, coke and ironcontaining charge in blast furnace dust, which comprises the following steps: 1) determining the true density of materials; 2) preparing a separating medium; 3) carrying out centrifugal separation on the furnace dust; 4) measuring and calculating the weight percentage content of settled coal and ...
Abstract. The functional and group composition and structure of β and α 2 fractions of mediumtemperature coal pitch fraction (in powder form) are investigated by methods such as elemental analysis, electron microscopy, IR spectroscopy, ESR, Xray diffraction analysis, derivatographic analysis, and chromatography and mass spectrometry. The morphology and structure of the coke residues from ...
Next, Meng et al. [35] showed that the tensile strength of coal coke was approximately MPa, which was lower than the BioCoke, which could be due to the microstructural features of the coal coke that contained pores. ...

Cocoa powder, an unsweetened chocolate product, adds deep chocolate flavor to desserts and beverages. Cocoa powder occurs when the fat, called cocoa butter, gets removed from the cacao beans during processing. The leftover dried solids get ground into the product sold as cocoa powder.
Activated charcoal is a fine black powder made of coconut shells, coke, coal, olive pits and sawdust. These ingredients are activated at a very high temperature and so activated charcoal is porous and devoid of toxic substances which are usually present in barbecue charcoal.
FTIR analysis of coke sample from wastewater was also performed. The coking wastewater is from Yima gasification plant, Henan province. FTIR result of coke sample from wastewater suggests that C C, CH 3, C O and OH exist in coke powder, which is similar to the result of coal powder. C O and OH, these two critical function groups can be found in the coal powder and coke sample.
