Bituminous coal is found in veins in sedimentary layers and is one of the two mineral sources of fuel. When processed at a smelter or magma smelter, one unit of bituminous coal produces 9 units of coke. If done at a regular smelter, this processing requires one pre-existing unit of fuel (either charcoal or coke), leaving a net production of 8 fuel.

The results showed that compared with bituminous coal, the pore structure of lignite coal changed more obviously, which was manifested as follows: significant increases in porosity, pore diameters, and pore area; a larger transformation from micropores and transition pores to mesopores and macropores.
The co-firing of bituminous coal with woody biomass provided an available approach for cutting carbon emissions. In this work, a study on the application of high blending ratios of biomass with coal in co-firing was experimentally conducted in a lab-scale drop tube furnace (DTF) to reduce CO 2 emissions and control deposition and corrosion …

Anthracite coal is the highest-quality coal, with high carbon content and low moisture. It burns efficiently, producing intense heat and minimal smoke, making it ideal for open fires. Bituminous coal is a mid-grade coal with higher carbon content than others but produces more emissions. Choose anthracite for cleaner and longer-lasting open fires.
Bituminous is the most abundant rank of coal. It accounts for about 50% of the coal produced in the United States. Bituminous coal is formed when a sub bituminous coal …
Pulverised coal samples and its combustion products were analysed for major element using Axios instrument (PANalytical) with a 2.4 kWatt Rh X-ray Tube. Further, the same set of samples were analysed for trace element using LA-ICPMS instrumental analysis. LA-ICP-MS is a powerful and sensitive analytical technique for …
One subbituminous coal from Fukang (FK) colliery in the southern Junngar Basin and another bituminous coal from Malan (ML) colliery in the northwest Qinshui Basin were collected, which were drilled for cylindrical cores with 25 mm in diameter and 50 mm in length approximately. ...

A coal fire is one of the most serious disasters in coal mining. To improve the efficiency of an inert gas for extinguishing the fire, the adsorption behavior of coal in CO2/N2 mixed gas was investigated in this study. Proximate analysis, ultimate analysis, solid-state 13C nuclear magnetic resonance spectroscopy (NMR), X-ray photoelectron …

Studying on the pore size distribution of coal is vital for determining reasonable coalbed methane development strategies. The coalbed methane project is in progress in the southern Junggar Basin of northwestern China, where high volatile bituminous coal is reserved. In this study, with the purpose of accurately characterizing …
Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. Bituminous: …
Bituminous coal is perhaps the most popular fuel for rotary kilns. It is quite abundant in many parts of the world, occurs in sedimentary rock formations, and is often located …

In a group of deep coal seams, mining of upper multilayers generates cyclic loading–unloading stresses in bottom layers, improving their permeability and enhancing coalbed methane gas drainage. In this study, the respective repeated mining stress path was introduced into the seepage test. A high-resolution 3D X-ray microscopy imaging …

High-volatile bituminous coal samples were reacted in deionized water with supercritical CO2 (ScCO2–water) under simulated in situ pressure and temperature conditions (8 MPa and 40 °C) in unconfined stress state for 14 days, in order to characterize potential CO2–water–coal reactions. Micro-structural changes were identified pre- and …
Bituminous coal is formed when a sub bituminous coal is subjected to increased levels of organic metamorphism. It has a carbon content of between 77 and 87% on a dry ash-free basis and a heating value that is much higher than lignite or sub bituminous coal. On the basis of volatile content, bituminous coals are subdivided into low-volatile ...
