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 ...

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.

Effects of Lignite Properties on the Hydroliquefaction Behavior of Representative Turkish Lignites
Energy Sources, 1992This paper reports on the conversion and yield data obtained for hydroliquefaction of 11 different Turkish lignites in tetralin, anthracene, and creosote oils with or without catalyst at 440{degrees}C and 80 bar that were correlated with the lignite properties obtained from proximate, ultimate, and petrographic analyses.

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.

The rates at which lignite is solubilized by the extracellular products of aPenicillium fungus designated as RWL-5, four substrains isolated from RWL-5 andStreptomyces flavovirens were examined. The effects of lignite surface oxidation were also examined. Comparison of data generated from studies with the two microorganisms suggested thatS. flavovirens

The first demonstration that samples of lignite at a depth of 10 m are considerably enriched in bacteria is reported. According to direct microscopy, the abundance of bacteria was about 107 cells/g. About 70% of cells had intact cell membranes and small size, which points to their anabiotic state.
