When scaling up new processes involving complex feedstocks, such as biomass, well-defined mixing is key. Guidelines presented here will help to efficiently move biomass hydrogenation reactions from the laboratory to commercial-scale operations One of the most promising pathways to biomass-based,…
Liquid-liquid extraction (LLE) is a separation technique that exploits differences in the relative solubility of compounds of interest (the solute) in two immiscible liquids — most often an aqueous phase and an organic solvent. This one-page reference reviews basic information…
Chlorum Solutions LLC (São Paulo, Brazil) will use thyssenkrupp nucera AG & Co. KG (Dortmund, Germany) technology for its next two chlor-alkali plants in Brazil. The company has ordered two skid mounted plants with BM2.7 electrolysis technology from the supplier…
Batch reactors are widely used throughout the chemical process industries (CPI), and the basic design has not radically changed for many decades. Nevertheless, precise temperature control of batch processes continues to be a common problem. Now, a new design of…
The startup company RenewCO2 (Piscataway, N.J.; www.renewco2.com) has developed a catalyzed electrochemical process for selectively producing monoethylene glycol (MEG) in a single step using byproduct carbon dioxide from other processes as feedstock. MEG is important industrially because it is the…
Magnesium metal is important for several emerging potential sustainability-related applications, including carbon capture, low-carbon cement and energy storage. These potential applications are driving efforts to efficiently produce magnesium hydroxide, the raw material for manufacturing Mg metal. It is possible to…
An emerging electrolyzer technology for renewable hydrogen production is the anion-exchange membrane (AEM), which provides efficiency and cost benefits over other electrolyzer configurations. Until now, most AEM installations have been small, as the membrane assemblies’ size and durability limited the…
Catalysts by AM In late September, BASF SE (Ludwigshafen, Germany; www.basf.com) introduced X3D, a new additive-manufacturing (AM; 3D printing) technology for shaping catalysts. Catalysts produced with this technology feature an open structure, resulting in a reduction of the pressure drop…
Scientists at the U.S. Dept. of Energy’s Brookhaven National Laboratory (BNL; Upton, N.Y.; www.bnl.gov) and collaborators at Cold Spring Harbor Laboratory (CSHL; Laurel Hollow, N.Y.; www.cshl.edu) have genetically engineered a strain of duckweed (Lemna japonica) to produce high yields of…
Hollow silica particles (HSPs) are materials of interest for thermal insulation applications because of their very low thermal conductivity, but the particles pose health hazards and the powder is impractical to use, so scientists have been trying to incorporate HSPs…
