Low-temperature plasma process supports direct recycling of battery cathodes
Direct battery-recycling methods, such as re-lithiation — where depleted lithium is replenished directly onto cathodes via a solid-state reaction — hold many benefits over indirect methods, such as those relying on hydrometallurgy or pyrometallurgy, where cathodic structures are destroyed in…
Process for cellulose-derived pigments scales up to hundreds of tons/yr
A process for making pigments from cellulose for use in cosmetics, food and coatings applications has scaled up from a 1-ton/yr pilot unit to a process capable of generating multiple-hundreds of tons per year in a toll-manufacturing setting. The cellulose-derived…
Unique support boosts single-atom indium catalysis of CO2-to-methanol reaction
Synthesis of methanol from carbon dioxide is among the key goals for net-zero-CO2 production of chemicals and fuels. Previous investigation has suggested that indium oxide could serve as an effective catalyst for this reaction, but the structural details of the…
Fundamentals of Reactor and Vessel Design
This article made available to you by: This article provides an overview of the engineering, design and operational considerations associated with reactors and vessels, bridging the gap between theoretical design codes and applied process engineering Pressure vessels and reactors are…
Editor’s page: From ‘automated’ to ‘autonomous’
The continued and expanding use of digitalization technologies in the process industries have pushed facility operations from “automated” — featuring distributed control systems, programmable logic controllers, safety instrumented systems and others — toward “autonomous” operations, where technologies like machine-learning, open-software-defined…
Electrochemical-redox process expands recycling potential for LFP batteries
Lithium-iron-phosphate (LFP) batteries offer a compelling combination of performance characteristics for stationary energy storage, including improved safety and longevity, when compared to other lithium battery chemistries, such as nickel- and cobalt-based formulations. However, there are limited recycling pathways dedicated to…
Rotating bioreactor scheme accelerates production of high-value products
A team of researchers at Iowa State University (ISU; Ames; www.iastate.edu) have developed a new bioreactor concept that streamlines production of value-added bioproducts at smaller scales by integrating three process steps (fermentation, product extraction and separation) into a single, compact…
Modular, low-cost ammonia-production system is designed for intermittent energy
Ammonia is a critical input for agricultural fertilizers, but NH3 production is plagued by volatile prices, difficult global logistics and high CO2 emissions. A new NH3-production system from the startup TalusAg (Austin, Texas; www.talusag.com) addresses these challenges with a modular…
Customizing Bulk-Solids Mechanical Conveyors for the CPI
For effective mechanical conveying of bulk solids in the chemical process industries (CPI), equipment should be tailored to the specific needs of the solids-handling application The sheer diversity of bulk-solid materials encountered across the chemical process industries (CPI), including agricultural…
Waterless technology uses supercritical CO2 to recycle textile waste
Textile waste is one of the fastest-growing waste streams globally, and there are limited options available to efficiently recycle end-of-life textiles into useful materials. A new recycling approach developed by Renasens (Stockholm, Sweden; www.renasens.com) utilizes supercritical CO2 to recover intact…
