In adsorption processes using steam to regenerate activated carbon, the carbon’s physical characteristics can greatly impact efficiency and optimization Processes using activated carbon as an adsorbent (Figure 1) can be ideal candidates for regeneration using hot fluids like CO2, CH4,…
Recycling vehicle tires is complicated because the rubbers used (including butadiene and polyisoprene) are highly cross-linked, and because pyrolysis-based recycling of the rubbers generates environmentally hazardous compounds like benzene and dioxins. Now, researchers at the University of North Carolina at…
A proprietary molten-salt electrolysis (MSE) process originally designed for battery manufacturing has now been re-optimized for North America’s first operational cobalt-refining plant. The DirectPlateTM MSE technology developed by Xerion Advanced Battery Corp. (Kettering, Ohio; www.xerionbattery.com; see Direct molten-salt electroplating cuts…
Biogas — produced from anaerobic digestion of organic matter — contains a mixture of gases, with methane and carbon dioxide as the predominant components. To use biogas as a fuel source, purification of the gas is typically needed to remove…
The ability to economically produce large scales of graphene will help to enable many high-performance applications, from smart packaging materials and medical devices to safer gas storage. A new process demonstrated at Southwest Research Institute (SwRI; San Antonio, Tex.; www.swri.org)…
