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 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…
For novel process technologies, each development stage brings new safety obligations. This guide provides a practical framework for navigating safety responsibilities from early R&D to commercialization Developing new process technologies — especially those involving hazardous materials or operations at high…
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…
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…
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…
The barrier-management approach to process safety can help organizations better understand and proactively address the risk inherent in their operations Facilities in the chemical process industries (CPI) have many barriers in place to prevent or limit the effects of a…
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)…
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…
Water contamination from per- and polyfluoroalkyl substances (PFAS) compounds is one of the most significant environmental and health issues globally. In particular, effectively breaking the carbon-fluorine bonds that are paramount to the stability and persistent nature of PFAS is extremely…
