Producing hydrogen via methane pyrolysis – termed ‘turquoise hydrogen’ – has thus far received less attention than ‘blue’ and ‘green’ H2, but it may offer advantages over both While the vast majority of current hydrogen production occurs by steam reforming…
‘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”…
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…
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…
Bio-acrylonitrile Site selection is underway for a glycerol-to-acrylonitrile demonstration-scale plant that will enable the production of plant-based acrylonitrile (ACN). Trillium (Knoxville, Tenn.; www.trilliumchemicals.com) is partnering with Zeton (Oakville, Ont.; www.zeton.com) to design and build the plant, known as Project Falcon.…
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,…
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…
Bioresorbable polymers — those that degrade naturally over time and can be absorbed by the body — are essential for delivering a number of advanced biomedical technologies to patients, including long-acting injectable or implanted products, regenerative scaffolds, degradable medical devices,…
Asset criticality and risk are primary among the many factors that must be considered to appropriately manage valves throughout their lifecycle Asset strategies usually define how assets will be treated in the different phases of an asset lifecycle, from acquisition…
Last month, Metso Corp. (Espoo, Finland; www.mogroup.com) introduced a hydrogen-variant of its Ferroflame LowNOx burners as part of its NextGen Pelletizing plant product range. It is a first-of-its-kind burner to run on H2 and to operate on the LowNOx combustion…
