Building off of a process to efficiently manufacture graphene (see Chem. Eng., April 2022, p. 9), a team of researchers from Rice University (Houston, www.rice.edu) have uncovered that the process can be easily altered to also produce a nearly pure…
The efficiency and cost effectiveness of modularity provides advantages for small- and large-scale projects When the right conditions exist, the benefits of modular construction — from laboratory scale to large scale — are plentiful and allow single-source, cost-effective and efficient…
‘Turquoise’ hydrogen processes generate H2 without releasing CO2. Presented here are the opportunities and challenges for producing hydrogen by methane pyrolysis Hydrogen-producing processes are classified using a color scheme according to their carbon footprint (Table 1; [1–3]). So-called “turquoise hydrogen”…
The Vilsmeier reagent (VR), [(CH3)2 NCHCl]Cl, is necessary for producing a large range of pharmaceuticals, but it is unstable in air and is made from the toxic precursor phosgene (COCl2). A new flow-reactor system has been developed by Akihiko Tsuda,…
Coolbrook Oy (Helsinki, Finland; www.coolbrook.com) has successfully completed the first phase of large-scale pilot testing (photo) for its RotoDynamic Technology at the Brightlands Chemelot Campus in Geleen, the Netherlands. During 2023, Coolbrook has been running a test program to demonstrate…
Unipar (São Paulo, Brazil) is modernizing its chlor-alkali plant at the Cubatão plant in Brazil by incorporating electrolyzers from thyssenkrupp nucera AG & Co. KGaA (Dortmund, Germany; ). To modernize the plant, the Brazilian chemical company, a leader in the…
Electrolyzers are typically associated with the production of “green” hydrogen from water and renewable electricity, but a new device borrows from traditional electrolyzer principles to convert CO2 into propane. A team of researchers from the Electrochemical Energy Materials and Devices…
Construction is underway by AIR Co. (Brooklyn, N.Y.; www.aircompany.com) for a commercial demonstration plant capable of converting captured carbon dioxide into fuel-grade paraffins, as well as ethanol and methanol, in a single step. The facility will be a larger version…
Researchers at the Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu) have developed a new class of materials — enzyme foams. Normally, foaming modifies the enzyme structure and enzymes lose their biocatalytic activity. The new protein foams, however, are said to…
Covestro AG (Leverkusen, Germany; www.covestro.com) has developed a chemolysis process for recycling polycarbonate back into monomers. In laboratory trials, the process has been shown to recycle waste streams with more than 50% polycarbonate content into monomers, closing the loop to…
