Volatile Matter (Part of Proximate Analysis), Coal

Oct 07, 2019 Both volatile matter and fixed carbon are used to define coal rank in high-volatile, medium-volatile bituminous, and higher-rank coals in the U.S. classification system (ASTM method D388-12; American Society for Testing and Materials, 2013, p. 390–396). Along with moisture and ash contents, the percentage of volatile matter

Volatile Matter an overview ScienceDirect Topics

Volatile Matter. Volatile matter is defined as the gases driven off when coal is heated to 950°C (1742°F) in the absence of air under specified conditions and is consisted of short and long chain aliphatic carbon atoms (linked in open chains) or aromatic hydrocarbons (one or more six-carbon rings characteristic of benzene series) and some sulfur.

Volatility (chemistry) Wikipedia

Volatility (chemistry) Bromine liquid readily transitions to vapor at room temperature, indicating a high volatility. In chemistry, volatility is a material quality which describes how readily a substance vaporizes. In at a given temperature and pressure, a substance with high volatility is more likely to exist as a vapor, while a substance

Coal assay Wikipedia

Volatile matter. Volatile matter in coal refers to the components of coal, except for moisture, which are liberated at high temperature in the absence of air. This is usually a mixture of short- and long-chain hydrocarbons, aromatic hydrocarbons and some sulfur. Volatile matter also evaluate the adsorption application of an activated carbon.

Coal Rank an overview ScienceDirect Topics

Volatile matter and maximum vitrinite reflectance are the most important rank parameters used to determine the value of a coking coal. Table 14.1 summarises the desired properties of coking coals (Mitchell, 1999e).As shown in Table 14.1, coals of good coking quality range in their volatile matter content (VM) between 15% and 45% (dry, mineral matter free (dmmf) basis) and in their vitrinite
