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…
A less expensive way to make graphene
A team from RMIT University (Melbourne, Australia; www.rmit.edu.au) and the National Institute of Technology, Warangal (Warangal, India; www.nitw.ac.in) has developed a cost-effective and eco-friendly way of producing graphene using a eucalyptus polyphenol solution extracted from eucalyptus bark. RMIT’s professor Suresh…
Chementator Briefs
Solar desalination Researchers at Rice University (Houston, Tex.; www.rice.edu) working on nanophotonics-enabled solar membrane distillation (NESMD) have found that concentrating sunlight on small areas of the desalination membrane leads to a non-linear improvement in performance in vapor pressure, which forces…
Microbial electrolysis produces hydrogen from organic waste
A modular, fuel-cell-like assembly featuring specially developed microbial communities is capable of producing pure hydrogen from a wide range of organic wastes. Developed by startup company Electro-Active Technologies (Oak Ridge, Tenn.; https://electroactive.tech), the microbial electrolysis system is now in the…
Bowl-shaped electrode enhances CO2 reduction
An international group of scientists has created a bowl-shaped electrode that can efficiently convert CO2 into carbon-based fuels and chemicals. The group includes scientists from the University of Bath (Bath, UK; www.bath.ac,uk), Fudan University (Shanghai, China; www.fudan.edu.cn), and the Shanghai…
Pilot plant slated for a H2-based process to make DRI from iron-ore fines
The use of direct reduced iron (DRI; sponge iron) and hot briquetted iron (HBI) is expected to continue to grow due to the need to reduce greenhouse gas emissions and the growing number of electric arc furnaces (EAFs) in service…
Poly-diketoenamines could allow closed-loop plastics recycling
Conventional plastics are difficult to recycle because end-of-life processing generally is either energy-intensive or alters the physical properties of the materials. A team of researchers from the Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) and the University of California at…
MOFs that mimic leaves for enhanced performance
Chemists from the research group of Stefania Grecea at the University of Amsterdam’s (UvA; the Netherlands; www.uva.nl) Research Priority Sustainable Chemistry have devised a way to enhance the practical performance of metal-organic frameworks (MOFs). By using leaves from the black…
Thermal insulation mimics polar-bear hair
Scientists from the University of Science and Technology of China (Hefei; https://en.ustc.edu.cn), led by professor Shu-Hong Yu, have developed a thermal insulator that mimics the structure of individual polar-bear hairs, and have scaled toward a material made of many hairs.…
A solvent-extraction approach for desalination of high-salinity brines
Hypersaline industrial wastewater brines are difficult to treat. Current approaches for removing salt from such brines — such as evaporative distillation and reverse-osmosis (RO) — are problematic because evaporation is highly energy-intensive and RO cannot handle salt levels present in…
