Extraction of Ge and synchronous activation of humic acid in germanium bearing lignite via oxidation leaching

Fuel Processing Technology
Germanium-bearing lignite was a crucial source for Ge extraction; however, existing methods focus on extracting Ge from lignite by-products, which overlooked its abundant organic matters.

Catalytic Hydroconversion of Model Compounds over Ni/NiO@NC Nanoparticles

Molecules
The conversion of lignite into aromatic compounds by highly active catalysts is a key strategy for lignite valorization. In this study, Ni/NiO@NC nanocomposites with a high specific surface area and a vesicular structure were successfully prepared via a ...

biogasification and combustion reactions of turkish lignites adsorption behavior and biogasification of soma lignite and co combustion of beypazari lignite with biomass

, 2012
In this study, our primary objective is to understand CBM capacity of the Soma coal basin. For this reason, porosity of the coal samples must be determined. Usually, surface area and the porosity of the materials can be calculated through the N2 physical sorption experiment, in this method entire relative pressure range (10-8 to 1) can be analyzed ...
