Analysis of Carbon Contents and Heavy Metals in Coal Samples Using Calibration-free LIBS Technique

open access: yesJournal of Spectroscopy, 2022
We report a compositional analysis of four coal samples collected from different mines in Pakistan and one Chinese brand. The coal samples were pelletized in the form of a disc and irradiated with a focused laser beam of fundamental (1064 nm) and second (

Reduction of Sulfur and Ash from Tabas Coal by Froth Flotation [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2007
Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high

Evaluating net life-cycle greenhouse gas emissions intensities from gas and coal at varying methane leakage rates

open access: yesEnvironmental Research Letters, 2023
The net climate impact of gas and coal life-cycle emissions are highly dependent on methane leakage. Every molecule of methane leaked alters the climate advantage because methane warms the planet significantly more than CO _2 over its decade-long ...
