Lignite, thermally-modified and Ca/Mg-modified lignite for phosphate remediation [PDF]

open access: yesScience of The Total Environment, 2021
Aqueous phosphate uptake is needed to reduce global eutrophication. Negatively charged adsorbent surfaces usually give poor phosphate sorption. Chemically- and thermally-modified lignite (CTL) was prepared by impregnating low-cost lignite (RL) with Ca2+ and Mg2+ cations, basified with KOH (pH ̴ 13.9), followed by a 1 h 600 °C pyrolysis under nitrogen ...

Study and Numerical Simulation on Explosion Propagation Characteristics of Lignite Dust [PDF]

open access: yesE3S Web of Conferences, 2020
In order to reveal the explosion propagation law of lignite dust in 20L spherical explosion test device, the dust diffusion behavior and explosion propagation characteristics of lignite were studied by experiment and numerical simulation. The propagation

Economic Resilience of German Lignite Regions in Transition [PDF]

open access: yes, 2019
This paper recalls the development of the German lignite regions Rhineland and Lusatia since 1945 to allow for a better understanding of their situation in 2019. We analyze their economic resilience, defined as adaptive capacity, using Holling’s adaptive

Thermal desorption of mercury from lignite in a high-temperature furnace and in power plant mills

open access: yesInternational 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 ...

Early maturation processes in coal. Part 1: Pyrolysis mass balances and structural evolution of coalified wood from the Morwell Brown Coal seam [PDF]

open access: yes, 2009
In this work, we develop a theoretical approach to evaluate maturation process of kerogen-like material, involving molecular dynamic reactive modeling with a reactive force field to simulate the thermal stress. The Morwell coal has been selected to study
