Abstract Samples have been taken systematically from a sequence of immature lignite deposited as a large reserve in Elbistan (37° 48′ N 37° 51′E) 1.5–2 m.y. ago during the Pliocene-Pleistocene transition. The lignite has a high volatile content of 60–70% and a huminite reflectance of 0.27 ± 0.03.

Effect of lignite properties on reactivity of lignite
Energy Conversion and Management, 2001The purpose of this study is to relate the combustion reactivity of lignite to its physical and chemical properties. Non-isothermal thermogravimetry, where the sample whose temperature increased at a linear rate (40 K/min) was heated in air, has been used to investigate the combustion reactivities of 25 lignite samples originating from different areas ...

ReaxFF-based molecular dynamics simulation of the initial pyrolysis mechanism of lignite
Fuel processing technology, 2019In this paper, a series of ReaxFF molecular dynamics (ReaxFF-MD) simulations were employed to explore the characteristics of pyrolysis products, transformation behavior of major elements, and thermal decomposition mechanism of lignite.

Investigation on the lignite pyrolysis reaction kinetics based on the general Arrhenius formula
, 2020Studying the reaction kinetics can deepen the understanding of reaction mechanism and provide a relatively accurate and efficient reaction rate expression to theoretically optimize the relevant reactor. Here, the complicated lignite pyrolysis was assumed

Senckenberg Lignite: A Lignitized Wood with Apparently Original Cellulose and Lignin
Science, 1969A lignitized wood of Miocene derivation has been identified to the genus Taxodium . The cell walls of latewood tracheids are Mäule positive. A structurally intact lignin residue is obtained after incubation of the wood in 72 percent sulfuric acid.

There is no doubt that Northern Ireland's lignite deposits are of high quality and constitute a natural resource of considerable potential value in this small, peripheral part of the European Community. Whether or not one or more will be used commercially and, if so, when depends on an interacting complex of economic, social and political factors.
