Spotlight on hydrogen
Driven by climate-related concerns, interest in hydrogen for its potential to play a significant role in decarbonization is surging. An increased urgency to get on track with decarbonization targets set by governments and corporations for the next few decades has…
An electrochemical process for producing and recycling VRFB electrolytes
Electrochem Technologies & Materials Inc. (Montreal, Canada; www.electrochem-technologies.com) has recently patented its process for the production and recycling of all vanadium electrolytes (VE) used in vanadium redox flow batteries (VRFBs). This electrochemical technology offers a sound and profitable alternative to…
A more sustainable alternative for producing egg-white protein
Egg white is one of the most important protein ingredients for the food industry, with a market of 1.6-million ton/yr in 2020 and projected to grow in the future. Searching for sustainable alternatives to animal-based proteins has been of growing…
Demonstration plant will convert waste biomass into emissions-free hydrogen
A new demonstration plant near Bakersfield, Calif. will produce carbon-negative “green” H2 from woody biomass waste, such as agricultural residues from orchard trees and walnut shells. Developed by Mote, Inc. (Los Angeles, Calif.; www.motehydrogen.com), with engineering partners Fluor Corp. (Irving,…
This new thermoplastic elastomer has a large impact resistance
Thermoplastic elastomers (TPEs) are typically copolymers of a plastic and a rubber that have both thermoplastic and elastomeric properties. The best-known TPEs include styrenic block polymers, which contain molecular blocks of polystyrene (which is hard) and polydiene (which is rubbery).…
Renewable dimethyl ether plant planned
Engineering design is underway for a new plant for making renewable dimethyl ether (rDME) from biogas produced by agricultural digesters or derived from landfills. Project developer Oberon Fuels (San Diego, Calif.; www.oberonfuels.com) is basing the new plant on its existing…
Chementator Briefs
Drive & Charge The R&D teams from Holcim Ltd. (Zug, Switzerland; www.holcim.com) and Magment GmbH (Oberhaching, Germany; www.magment.co) have developed a unique concrete with high magnetic permeability, which enables electric vehicles to recharge wirelessly while in motion. Known as inductive…
Reducing the carbon footprint of quicklime production
Decomposing limestone (CaCO3) into quicklime (burnt limestone; CaO) releases significant CO2 emissions, both from the combustion of fuel needed to heat the kiln to temperatures over 1,000°C, and by the release of CO2 from the reaction itself (CaCO3 → CaO…
Technology Profile: Allyl chloride production
Allyl chloride (3-chloropropene; Figure 1) is primarily used almost exclusively as a chemical intermediate in the production of epichlorohydrin. A three-carbon epoxide, epichlorohydrin is used in the manufacture of epoxy resins prevalent in coatings, adhesives, and plastics. Epichlorohydrin is also…
