Drastic Enhancement Of Co2 Adsorption Capacity By Negatively Charged Sub-Bituminous Coal, Hussein R. Abid, Stefan Iglauer, Ahmed Al-Yaseri, Alireza Keshavarz

Research outputs 2014 to 2021

Climate change is a key problem of the 21st century. Climate change is mainly caused by anthropogenic CO₂ emissions, and one solution to this problem is to capture and store CO₂ in deep coal seams, where it is immobilized by adsorption to the coal surface. Here we propose to modify the coal with methyl orange (MO), a typical dye that is also a major pollutant of the hydrosphere and removed thereby. Thus, raw and MO-modified coals were characterized to investigate their thermal stabilities, textural properties, carbon contents, surface characteristics, and CO₂ adsorption on the coal samples was …
