Engineered microbes convert C1 feedstocks into longer-chain chemicals
Researchers at the University of South Florida (USF; Tampa, Fla.; www.usf.edu) have developed a microbial metabolic pathway that allows enzymatic conversion of one-carbon compounds into multi-carbon intermediate chemicals. The bioconversion process, which takes place in genetically engineered bacteria, could enable…
Driving Toward a Hydrogen-based Economy
Technology developments are progressing towards large-scale production of ‘green’ hydrogen, along with improved methods for storage and transportation The world has an important opportunity to tap into hydrogen’s vast potential to become a critical part of a more sustainable and…
Laboratory Measurements Aid Process Efficiency
New laboratory instruments simplify the collection of accurate and consistent measurements to increase productivity and product quality Efficiency and optimization are key words when it comes to all aspects of chemical processing and the laboratory is no different. Like most…
Integrated e-waste processing facility nears completion
Although it contains many valuable metals, electronic waste (e-waste) is an exceedingly difficult material stream to process, and the vast majority of e-waste is not recycled. EnviroLeach Technologies Inc. (Vancouver, B.C.; www.enviroleach.com) is currently preparing to start up a first-of-its-kind…
This multifunctional photocatalyst splits water with visible light
Oxysulfide semiconductors have narrow bandgaps — a property that makes them suitable photocatalysts for water splitting under irradiation with visible light (640 nm wavelength). That’s because the electronegative sulfide ions negatively shift the valence band edges of the corresponding oxides.…
The outlook for hydrogen as an energy carrier
Many countries are now making rapid advances in hydrogen energy technologies and strategy, and the rest of the world has much to learn from their experience, according to a new report — Advancing Hydrogen — compiled by a team from…
These magnetic ‘nanosprings’ decompose microplastics
Microplastics — a subgroup of plastics with an effective diameter less than 5 mm — are ubiquitous pollutants. They adsorb organic and metal pollutants that are ingested by aquatic organisms, and accumulated all the way up the food chain. Using…
New research solves debate over water-gas shift reaction mechanism
The water-gas shift reaction (WGS; in which water vapor is reacted with carbon monoxide over a copper-chromium-iron-oxide catalyst to yield hydrogen and CO2) is of paramount importance to the chemical industry, as it is a primary route to producing H2…
New oxocatalyst demonstrated for vinyl chloride monomer production
Recently, Tosoh Corp. (Tokyo, Japan; www.tosoh.com) has applied a new, proprietary oxocatalyst in the oxychlorination process for making ethylene dichloride (EDC) from ethylene, HCl, and O2 in its vinyl chloride monomer (VCM) manufacturing process. The performance boost anticipated from simulation…
Commercial debut for an upgrading process
After four years of project development and execution, the new PolyFuel unit at Petrobrazi petroleum refinery in Romania has been started-up and is fully functional since April 2019. Based on the PolyFuel technology licensed by Axens (Rueil-Malmaison, France; www.axens.net), the…
