Vitrinite confirms the discovery of very high-quality coking coals at the wholly-owned Karin Basin deposit (EPC 1241) within Queensland's Bowen Basin. Initial test work has returned Maximum Fluidity results of up to 30,000 ddpm with RoMax of up to 0.95 and Crucible Swell Numbers of up to 9.

Vitrinite Reflectance - an overview | ScienceDirect Topics

Vitrinite reflectance measurements were obtained for almost all of the samples. However, for a high proportion of samples, the readings come from a small number of phytoclasts, and in some cases, from only a single plant entity. It is clear that plant and tissue types are the main control over the values obtained rather than thermal history.

Vitrinite is one of the primary components of coals and most sedimentary kerogens.Vitrinite is a type of maceral, where "macerals" are organic components of coal analogous to the "minerals" of rocks.Vitrinite has a shiny appearance resembling glass (vitreous). It is derived from the cell-wall material or woody tissue of the plants from which coal was formed.

Vitrinite reflectance, like all maturity indicators, is a trend tool. A valid data set should consist of 10–20 vitrinite reflectance sample analyses spanning a depth range of a minimum of 4000–5000 ft (approximately 1200–1500 m). Mean reflectance values of the in situ vitrinite population from each sample should be plotted on a log scale ...

Hardgrove grindability index (HGI) - SlideShare

A type of woody kerogen that is relatively uniform in composition. Since vitrinite changes predictably and consistently upon heating, its reflectance is a useful measurement of source rock maturity. Strictly speaking, the plant material that forms vitrinite did not occur prior to Ordovician time.

In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.: 620 Hydrocarbons are examples of group 14 hydrides.Hydrocarbons from which one hydrogen atom has been removed are functional groups called hydrocarbyls. Hydrocarbons are generally colourless and hydrophobic with only weak odours. Because of their diverse molecular structures, it is difficult ...

Vitrinite

Oct 07, 2019· Vitrinite reflectance is the proportion of incident light reflected from a polished vitrinite surface. Vitrinite is a maceral (an organic component) of coal. As vitrinite is heated in the earth during burial, it systematically changes its reflective properties.

Metallurgical Use of Heat Altered Coal: A Case Study

HUMINITE AND VITRINITE. The humic macerals in the samples are dominated by low-reflectance humic materials. In terms of the definitions of ICCP (1971), the low reflectance forms should be referred to huminite. However, this material becomes vitrinite at higher levels of rank, and the use of huminite is considered by many authors to be confusing.

GeoImage™ Measurement System features point counting module.

Vitrinite is a common type of organic matter whose reflectance increases with increasing temperature and it is widely used in the hydrocarbon exploration industry as an indicator of the temperature of hydrocarbon source rocks. The reflectance is measured with a microscope under oil immersion and using photomultiplier, and is expressed as a percentage in terms of reflection of the incident ...
