Inertinite - Wikipedia
Inertinite refers to a group of partially oxidized organic (mainly plant) materials or fossilized charcoals, all sharing the characteristic that they typically are inert (i.e. not altered) when heated in the absence of oxygen. Inertinite is a common maceral in most types of coal.
惰质组 - 百度百科
惰质组(inertinite)是指植物残骸主要受丝炭化作用转化而成的煤岩显微组分组。又称丝质组。用光学显微镜观察时，它们在透射光下呈黑色。不透明，在油浸反射光下，呈白色到黄白色，有不同程度突起。
The new inertinite classification (ICCP System 1994)
2001年3月1日 · Partially fusible and infusible inertinite acts as leaning material in coal blends, but improves coke strength when finely dispersed. An optimum content of inertinite is beneficial in obtaining a coke of maximum strength and stability. The amount is rank dependent. Coke strength is also affected by the size of the inertinite in the blend [12 ...
煤的显微组分定义与分类 (ICCP system 1994)解析II:惰质体
1 惰质体 (Inertinite)概述. 1.1 惰质体的定义和分类. 起初，提出惰质体这一术语是为了简化煤岩学的术语名称，基于丝质体、半丝质体、菌类体和微粒体这4种显微组分在光学和化学工艺性质上具有相似性，而将它们组合成一个名称，称之惰质体 [1]。 顾名思义，“惰质体”这一术语表明，它比镜质体和类脂体具有明显的惰性，特别是在碳化过程中惰性尤为明显。 “ICCP system 1994”将惰质体定义为:惰质体为显微组分组，在低、中阶煤和低、中变质程度的沉积岩中，惰质体显微组分的 …
Inertinite | maceral group | Britannica
The inertinite group makes up 5 to 40 percent of most coals. Their reflectance values are usually the highest in a given sample. The most common inertinite maceral is fusinite, which has a charcoal-like appearance with obvious cell texture. The cells may be either empty or….
Observations and experiments on the origin and formation of inertinite ...
2007年4月2日 · Introduction. The ICCP define inertinite as “Inertinite is a maceral group that comprises macerals whose reflectance in low- and medium rank coals and in sedimentary rocks of corresponding rank is higher in comparison to the …
Review and update on the applications of inertinite macerals in …
Inertinite is a coal component group recognized under microscope. The origin, formation, and applications of inertinite continue to be debated. Many important achievements have been reported in the recent years. The most important advance is that the presence of inertinite macerals has been used as the most critical evidence of paleowildfires.
Characteristics and evolution of inertinite abundance and …
2021年5月20日 · Coal, especially the inertinite in it, is highly sensitive to climate changes, showing an obvious response to paleoclimate conditions, in particular, to paleo-oxygen concentration (pO2). In this study, the inertinite abundance data of typical coal-forming periods in China were systematically collected and analyzed.
Differences in Molecular Structure between Vitrinite and Inertinite …
2023年12月12日 · Vitrinite is a product of the gelification process of plant lignocellulosic tissue during coal formation. Compared with inertinite, vitrinite has a higher oxygen content and a slightly lower carbon content.
Inertinite in coal and its geoenvironmental significance ... - Springer
2024年5月14日 · Inertinite, as an important and abundant maceral group in coal, is critical for the study of palaeowildfires and their roles in the Earth’s ecosystems. Recently, there has been a significant amount of research on the relationship between palaeowildfire, palaeoclimate change and palaeovegetation evolution based on inertinite data.
