The momentum continues for sustainability projects, as successful sustainability programs are found to be essential for business success Last month, this column discussed the continuing momentum of sustainability…
The CO2 electrochemical reduction reaction (CO2RR) has intrigued scientists for decades as a way to make fuel and chemicals from the greenhouse gas CO2. Prior research identified copper as a CO2RR catalyst, and has revealed the active sites where electrocatalysis…
Rotary kilns, essential in catalyst production, require diligent maintenance. Key considerations are presented here Rotary kilns are essential to catalyst production, facilitating the thermal treatment conditions necessary to help ensure that catalysts can meet performance expectations as efficiently as possible.…
The market for lithium-ion batteries continues to grow, driven by demands for consumer electronics, renewable energy storage and electric vehicles. The manufacture of these batteries is itself energy-intensive, with production steps that typically involve creating a slurry for a wet-coating…
Hydrogen can be a zero-emissions fuel source, but its storage and transportation are costly and problematic, limiting its widespread use. Liquid organic hydrogen carriers (LOHCs), in which hydrogen atoms are chemically bound to liquid hydrocarbons via reversible hydrogenation reactions, offer…
A “plug-and-play” microbial technology enables the recovery of additional copper from low-grade ores when used alongside traditional sulfuric-acid heap-leach methods. Working synergistically within the existing heap-leach infrastructure, the unique microbial communities that have been cultivated by Endolith (Westminster, Colo.; www.endolithmining.com)…
A new gasification process designed for the disposal of biosolids is also capable of destroying per- and polyfluoroalkyl substances (PFAS) contaminants, which are typically very resistant to conventional treatment processes. Aries Clean Technologies (Franklin, Tenn.; www.ariescleantech.com) recently validated its fluidized-bed…
Innovative burner and combustion systems optimize combustion, improving safety, effectiveness and efficiency while lowering emissions In burner and combustion operations, chemical processors must balance emissions and safety requirements with achieving optimal system performance in a cost-effective way. Further, many chemical…
Pneumatic conveying uses air to either push (positive pressure) or pull (negative pressure) solid material through a conveying line. The characteristics of the solid materials being conveyed play a significant role in how the pneumatic conveying system is designed and…
Bulk-solid waste materials present unique handling challenges. Presented here is a discussion on how to navigate those challenges, along with some characterization strategies to avoid them Across industry sectors, solid waste materials are common and highly varied. The complexities of…
