CO2 is the main greenhouse gas in Earth's atmosphere, and has been causing global warming since the industrial revolution. Therefore, technologies to mitigate carbon emissions have attracted extensive research. Shale gas reservoirs could serve as potential sequestration space for CO2. This paper aims to gain insight in the CO2 adsorption behavior a...

Chemical-looping combustion (CLC) is a promising technology that utilizes metal oxides as oxygen carriers for the combustion of fossil fuels to CO2 and H2O, with CO2 readily sequestrated after the condensation of steam. Thermally stable and reactive metal oxides are desirable as oxygen carrier materials for the CLC processes. Here, we report the pe...

Thermal regeneration of spent activated carbons (SACs) is widely used in industry. However, low specific surface areas (SBET) of regenerated activated carbons (RACs) are achieved after thermal regeneration, constraining the adsorption of contaminants. Herein, a green chemical mixture of K2CO3 and KCl compared to conventional activating agents was u...

This paper reports the overall reaction mechanism of JP-10 pyrolysis obtained in large-scale reactive molecular dynamics simulations employing the force field of ReaxFF CHO-2008. The C B4 > B2 > B5 > B1 > B6 > B7 that will not be significantly affected by temperature. The obtained aromatic hydrocarbons in simulations and the increasing C/H ratio w...

To further increase combustion efficiency and reduce nitrogen oxide pollution caused by tannery wastes, three raw materials, including tannery sludge, chrome-tanned buffing dust, and chrome shavings, were burned together in a dual-bed model reactor under various conditions. In addition, a thermogravimetric analysis of co-combustion of three tannery...

Chemical looping (CL) technology using an oxygen carrier (OC) offers a versatile platform to convert various fuels (e.g., CH4, coal, and biomass) to value-added products (e.g., heat, syngas, and H2) in a clean and efficient approach. Currently, the migration and transformation mechanisms of lattice oxygen in spinel OCs were not extensively investig...

The development of processing techniques for the extraction of rare earth elements and critical minerals (REE/CM) from acid mine drainage precipitates (AMDp) has attracted increased interest in recent years. Processes under development often utilize a standard hydrometallurgical approach that includes leaching and solvent extraction followed by oxa...
