1.1 Bituminous And Subbituminous Coal Combustion

from coal combustion are primarily sulfur dioxide (SO 2), with a much lower quantity of sulfur trioxide (SO 3) and gaseous sulfates. These compounds form as the organic and pyritic sulfur in the coal are oxidized during the combustion process. On average, about 95 percent of the sulfur present in bituminous coal will be emitted as gaseous SO x

Bituminous type coals have just 2 subtypes call steam coal / thermal coal & metallurgical coal. Metallurgical coal also called coking coal is coal that is baked in ovens in complete absence of oxygen and at great temperatures as high as 2010°F. This type of process is what is called pyrolysis.

Bituminous Coal - an overview | ScienceDirect Topics

As for bituminous coal liquefaction technology, the R&D program of the NEDOL process started in 1984. Fig. 4.69 shows a flow diagram of the NEDOL process (Wasaka, 1999b; Wasaka et al., 2003). The NEDOL process liquefies coal by using a Fe-based catalyst and hydrotreated solvent under relatively mild reaction conditions of 430–460 °C and hydrogen pressure of 15–20 MPa.

Coal - Origin of coal | Britannica.com

Coal - Origin of coal: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms. (It should be noted that peat can occur in temperate regions [e.g., Ireland and the ...

The Roles of Coal and Coke in Steelmaking

Jul 16, 2014· Metallurgical coke, or met coke, is manufactured from blends of bituminous coal in a heated distillation process resulting in a non-melting carbon. Coke is made by one of two processes: by-product or non-recovery, also known as heat recovery. In by-product coke making, impurities are driven off the coal in order to leave nearly pure carbon.
