Thermal desorption of mercury from lignite in a high-temperature furnace and in power plant mills
International Journal of Coal Science & Technology, 2022 In this article, the binding forms of two lignite samples are determined by thermal desorption using a high-temperature furnace. Each mercury compound, such as HgCl2, has a specific binding strength whose decomposition requires a certain thermal energy ...

Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1910 Abstract In 1863, Heer and Pengelly published in the ‘Phil. Trans.’ an account of these lignite-beds and their flora. Heer classed the lignite as Lower Miocene, considering it equivalent to the Aquitanian of Prance and to the Hamstead Beds of the Isle of Wight.
