The minerals in 12U Coal are predominantly chlorite, quartz, and calcite, while the minerals in 12L Coal consist mainly of illite, quartz, chlorite, kaolinite, and mixed-layer illite/smectite (I/S). Mineral matter is generally considered to consist of all the inorganic minerals (discrete phases), as well as all elements (apart from C, H, O, N and S) that are in, or associated with, by: This review (1) describes and classifies the geological, physical, and chemical occurrences of mineral matters in coal; (2) summarizes analytical methods used to characterize the mineral matter; and (3) compares the mineral-matter composition of Illinois coals with that of other U.S. coals.

given in Table Synthetic coal ashes were produced with coals blended with different minerals, the coals with combusted at conditions essentially, identical to those found in suspension fired furnaces. The changesin the coal ash mineral matter was brought about by addition of different additives such as Na. 2. O, K. 2. O,Al. 2. O. 3, P. 2. desirable aspects associated with the mineral matter in the coal. The mineral matter may be a catalyst for some of the current or future uses of coal. Specifically, the mineral matter could have some effect on combustion and also on future synthetic fuels efforts that could provide either gaseous or liquid fuels. At more than 50 percent mineral matter, the rock would be termed a carbonaceous shale rather than coal. Most mined coals are less than 20 percent mineral matter, and many coal contracts require less than 10 percent ash yield, which is approximately (but generally less than) the actual mineral matter content of a coal. adventitious mineral matter is transformed directly to ash in the combustor, and the shape is ly, mineral matter in coal and wood is contained within the organic matrix in the form of chemically bound molecules and submicron ng does not liberate this intrinsic mineral char combustion the.
