New evaporative crystallizer design accelerates direct-air carbon capture
A novel crystallizer has shown promise in lowering costs for direct-air capture (DAC) of CO2 emissions. In recent work published in Nature Chemical Engineering, a research team from the University of Toronto; www.utoronto.ca), led by mechanical and industrial engineering professor…
Field-trials upcoming for salt-based thermal-energy storage demonstration program
Field trials are expected to begin shortly for a high-temperature thermal-storage demonstrator built by AED Energy (London, U.K.; www.aedenergy.com). The field trials follow the successful completion of a test program of the demonstrator at AED’s London facility. The test program,…
Electrochemical route to extracting lithium ions from ‘black mass’ could lead to more efficient battery recycling
Black mass is the powdered material resulting from shredding end-of-life lithium-ion vehicle batteries. For effective recycling, lithium must be efficiently separated from this material, but conventional methods, such as smelting at high temperatures or dissolving in strong acids, require large…
Project reveals insights about catalysts for microwave-assisted methane dehydroaromatization
Several situations, including when takeaway capacity is limited at remote oil-well sites, result in methane flaring. To avoid wasting that resource, several strategies have been explored to convert methane onsite into commercially useful liquid chemicals. One of the approaches is…
A superconducting magnet for hydrogen liquefaction is demonstrated in Germany
A first-of-its-kind demonstration unit is showcasing hydrogen liquefaction using magnetocaloric cooling, a process that demands much lower energy consumption than conventional methods used in industry. A joint venture between Magnotherm Solutions GmbH (Darmstadt, Germany; www.magnotherm.com) and Helmholtz-Zentrum Dresden-Rossendorf (HZDR; Dresden,…
Novel chlorine-resistant membranes set new standards for reverse osmosis
A unique class of chlorine-resistant membranes is set to enhance the performance of processes requiring zero liquid discharge. NALA Membranes (Morrisville, N.C.; www.nalmembranes.com) has developed highly stable and durable membranes based on sulfonated polysulfone materials that overcome many of the…
‘Preorganization’ strategies allow polymer degradation through self-deconstruction
Designing plastics that can be broken down easily after their use phase have often required a trade-off between stability and ease of deconstruction. Recent research by scientists at Rutgers University (New Brunswick, N.J.; www.rutgers.edu) opens a path to resolve that…
Enzymatic splitting process cuts cost and energy consumption for fatty-acid manufacturing
Fatty acids are indispensable ingredients in a broad range of high-value products, including pharmaceuticals, cosmetics, food additives, industrial lubricants and many more. Current commercial production plants usually employ a thermal fat-splitting process that is often not economical for small- and…
Measurement and modeling point the way toward optimization of mechanochemical recycling
The widely used plastic polyethylene terephthalate (PET) can be depolymerized by reacting it with sodium hydroxide (NaOH) under strong mechanical impact from metal spheres in a ball mill. This type of mechanochemical route to recycling could alleviate some of the…
Two studies point the way to cleaner syngas-to-hydrocarbons processes
The production of commercially important hydrocarbons from synthesis gas (syngas; mixtures of H2 and CO) using the Fischer-Tropsch (F-T) process is a key strategy for making fuels and chemicals from a range of non-petroleum feedstocks. But F-T processes are relatively…
